Top heavy loads like campers and salt spreaders need more stability than a standard towing or hauling setup can give, and that is the job Timbren's Severe Service Kit was built to do. It uses a single-convoluted Aeon rubber spring that resists weight more aggressively than the standard Timbren spring, which keeps your RAM 3500 level and your ride smoother under a heavy, high-riding load. The springs have a progressive rate, so they push back harder as the load increases, and that works against squat, sway, and roll. When the camper is off or the spreader is empty, the springs sit with a gap above the frame, so the truck still rides comfortably instead of feeling stiff. There is nothing to maintain after installation, and unlike air bags there are no lines or pressure to keep an eye on. Timbren says you can install the kit and get back to work in under 30 minutes, right from your driveway. For anyone hauling a load that sits high and wants a steadier highway drive, this kit gives the rear of the truck real support.\u003c\/p\u003e\n\u003ch4\u003eSingle Convoluted Aeon Springs Engineered For Top Heavy Applications\u003c\/h4\u003e\n\u003cp\u003eThe Timbren DRTT3500D is a rear severe service SES kit engineered for 2011-2026 RAM 3500 trucks in 4WD and 2WD configurations, along with Ram 3500 Cab and Chassis models. It is built around two patented Aeon SES suspensions, which are hollow rubber springs that use a single-convoluted design made for applications like truck campers and salt spreaders. The kit is rated for 8,000 pounds of capacity. Kit height is 6.25 inches without the 1 inch spacer and 7.25 inches with it, and the two 1 inch rubber spacers are included in the box along with two steel mounting brackets and all necessary hardware. After installation, there should be a gap of 1\/2 inch to 1 1\/2 inches between the rubber spring and the vehicle frame, which is what gives you a comfortable ride when the truck is unloaded. The system needs no post-installation maintenance, and it is made of rubber rather than foam, which Timbren says holds up under all loads and in any weather. Adding this kit increases the spring rate but does not increase the truck's Gross Vehicle Weight Rating, so the load must never exceed the GVWR set by the manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026 RAM 3500 4WD\/2WD \u0026amp; RAM 3500 Cab \u0026amp; Chassis\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMade for top heavy applications such as truck campers and salt spreaders\u003c\/li\u003e\n\u003cli\u003eDoes not increase the GVWR, never exceed the manufacturer's Gross Vehicle Weight Rating\u003c\/li\u003e\n\u003cli\u003eAfter installation, there should be a 1\/2\" to 1 1\/2\" gap between the rubber spring and the vehicle frame\u003c\/li\u003e\n\u003cli\u003eRated capacity is 8,000 lbs\u003c\/li\u003e\n\u003cli\u003eKit height is 6.25\" without the 1\" spacer and 7.25\" with the 1\" spacer\u003c\/li\u003e\n\u003cli\u003eIncludes two Aeon SES rubber springs, two 1\" rubber spacers, two steel mounting brackets, and all necessary hardware\u003c\/li\u003e\n\u003cli\u003eRequires no post-installation maintenance\u003c\/li\u003e\n\u003cli\u003eManufacturer states the kit can be installed in under 30 minutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0693\/4560\/7962\/files\/Timbren_SES_Installation_Instructions_-_sku_DRTT3500D.pdf?v=1679422336\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Timbren","offers":[{"title":"Default Title","offer_id":54659454075164,"sku":"TIMDRTT3500D","price":398.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/DRTT3500D_1100x_d362cee9-85fc-4abc-b83a-8cf0d308ebfd.webp?v=1791219872"},{"product_id":"timbren-dr2500d-rear-ses-suspension-kit-2014-2026-ram-2500-4wd-2wd","title":"Timbren DR2500D Rear SES Suspension Kit | 2014-2026 RAM 2500 4WD\/2WD","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e8,600 lb rated capacity\u003c\/li\u003e\n\u003cli\u003eReduces sag, sway, and rear roll\u003c\/li\u003e\n\u003cli\u003eProgressive load support kicks in automatically\u003c\/li\u003e\n\u003cli\u003eAeon hollow rubber springs\u003c\/li\u003e\n\u003cli\u003eComfortable ride when unloaded\u003c\/li\u003e\n\u003cli\u003eNo air system to maintain\u003c\/li\u003e\n\u003cli\u003eZero post-installation maintenance\u003c\/li\u003e\n\u003cli\u003eDIY installation in under 30 minutes\u003c\/li\u003e\n\u003cli\u003eIncludes 1\" spacers, brackets, and hardware\u003c\/li\u003e\n\u003cli\u003eLifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStop The Squat When The Bed Is Full And The Trailer Is Hooked Up\u003c\/h4\u003e\n\u003cp\u003eA RAM 2500 is built for serious work, but even a heavy duty truck will squat and sway when you load it to the limit. If you pull equipment, haul material, or tow a fifth wheel for a living, that rear sag changes how the truck steers, how it brakes, and how settled it feels when a crosswind hits. Timbren's DR2500D Rear SES Kit was built for contractors, ranchers, and tow rig owners who depend on their truck every day. The Aeon hollow rubber springs stiffen as the load goes up, so the support kicks in on its own without you touching a switch or watching a pressure gauge. That progressive action works against squat, sway, and rear roll, which keeps the truck level and steady whether you are towing an RV across the country or hauling hay down the highway. When the truck is empty, a built in gap between the spring and the frame lets it ride comfortably instead of feeling stiff. Unlike air bags, there are no lines to check and no compressor to maintain, and Timbren says you can install the kit and be back to work in under 30 minutes from your driveway. For a work truck that hauls and tows on a regular basis, this is a simple way to keep the rear end under control.\u003c\/p\u003e\n\u003ch4\u003eHollow Aeon Rubber Springs With A Built In Gap For An Unloaded Ride\u003c\/h4\u003e\n\u003cp\u003eThe Timbren DR2500D is a rear SES suspension kit engineered for 2014-2026 RAM 2500 trucks in both 4WD and 2WD configurations. It is built around two patented Aeon SES suspensions, which are hollow rubber springs that deliver a progressive spring rate. As load increases, the springs push back harder, which reduces squat, sway, and roll. After installation, there should be a gap of 1\/2 inch to 1 1\/2 inches between the rubber spring and the vehicle frame, and that gap is what keeps the ride comfortable when the truck is unloaded. The kit is rated for 8,600 pounds of capacity. Kit height is 5.75 inches without the 1 inch spacer and 6.75 inches with it, and the box includes two 1 inch rubber spacers, two steel mounting brackets, and all necessary hardware. The system needs no post-installation maintenance and carries a lifetime warranty. Timbren points out that adding this upgrade increases the spring rate but does not increase the truck's Gross Vehicle Weight Rating, so the load must never exceed the GVWR set by the manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026 RAM 2500 4WD\/2WD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDoes not increase the GVWR, never exceed the manufacturer's Gross Vehicle Weight Rating\u003c\/li\u003e\n\u003cli\u003eAfter installation, there should be a 1\/2\" to 1 1\/2\" gap between the rubber spring and the vehicle frame\u003c\/li\u003e\n\u003cli\u003eRated capacity is 8,600 lbs\u003c\/li\u003e\n\u003cli\u003eKit height is 5.75\" without the 1\" spacer and 6.75\" with the 1\" spacer\u003c\/li\u003e\n\u003cli\u003eIncludes two Aeon SES rubber springs, two 1\" rubber spacers, two steel mounting brackets, and all necessary hardware\u003c\/li\u003e\n\u003cli\u003eRequires no post-installation maintenance\u003c\/li\u003e\n\u003cli\u003eManufacturer states the kit can be installed in under 30 minutes\u003c\/li\u003e\n\u003cli\u003eRear kit only, front SES kits are sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0693\/4560\/7962\/files\/Timbren_SES_Installation_Instructions_-_sku_DR2500D.pdf?v=1679421500\" target=\"_blank\" rel=\"noopener\"\u003eInstall Instructions\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Timbren","offers":[{"title":"Default Title","offer_id":54659597533468,"sku":"TIMDR2500D","price":269.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/DR2500D-ASD_1100x_1.webp?v=1791222431"},{"product_id":"carli-suspension-cs-dfsp-19-425-full-progressive-leaf-spring-kit-for-2-lift-2019-2025-ram-3500-4x4-diesel","title":"Carli Suspension CS-DFSP-19-425 Full Progressive Leaf Spring Kit –  for 2″ Lift | 2019-2025 RAM 3500 4X4 Diesel","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1-2\" of rear lift\u003c\/li\u003e\n\u003cli\u003eFull length two stage progressive spring pack\u003c\/li\u003e\n\u003cli\u003eBuilt by Deaver Spring Mfg for Carli\u003c\/li\u003e\n\u003cli\u003eSoftens initial spring rate at ride height\u003c\/li\u003e\n\u003cli\u003eMinimizes axle wrap and wheel hop\u003c\/li\u003e\n\u003cli\u003eUp to 15\" of suspension travel\u003c\/li\u003e\n\u003cli\u003eMaintains slight rear-high stance with Carli 3\" systems\u003c\/li\u003e\n\u003cli\u003eSmooth, comfortable street driving\u003c\/li\u003e\n\u003cli\u003eFor daily drivers and weekend warriors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSmooth Street Manners Without Giving Up The Weekend Trail\u003c\/h4\u003e\n\u003cp\u003eIf your RAM 3500 is a daily driver during the week and a trail rig on the weekend, the stock leaf springs are not really built for either job. Carli Suspension had Deaver Spring Mfg build these full length progressive spring packs specifically for this truck, and the goal was a balance of on and off road comfort. They use a two stage design, so the initial spring rate is softer at ride height, which is what gives you a smoother and more comfortable ride on pavement. As you load the truck or get deeper into the travel, the pack stiffens up so you still have a respectable weight capacity for work. The springs add 1 to 2 inches of rear lift, and that keeps a slight rear-high stance when you pair them with Carli's 3 inch systems. They also work to minimize axle wrap and wheel hop, which is the shudder and hop you feel when a heavy truck puts power down on a rough surface. With the factory shackle you get up to 15 inches of suspension travel, so the truck can actually use the suspension on a trail. For a diesel 3500 that has to work all week and play on weekends, this pack is built for exactly that mix.\u003c\/p\u003e\n\u003ch4\u003eTwo Stage Deaver Spring Packs Built Exclusively For Carli\u003c\/h4\u003e\n\u003cp\u003eThe Carli Suspension CS-DFSP-19-425 is a full progressive leaf spring kit engineered for 2019-2025 RAM 3500 4x4 diesel trucks with a 4.25 inch axle tube. The spring packs are full length and built by Deaver Spring Mfg specifically for Carli Suspension. They use a two stage design that softens the initial spring rate at ride height while still keeping a respectable weight capacity for the truck. The kit provides 1 to 2 inches of rear lift and maintains a slight rear-high stance when paired with Carli 3 inch systems. It minimizes axle wrap and wheel hop and is capable of 15 inches of suspension travel when used with the factory shackle. Buyers should know that these springs reduce the truck's payload to a light 3\/4-ton capacity.

The factory bottom overload spring has a very harsh spring rate, and that sudden jump in stiffness is what makes an empty or lightly loaded truck feel jarring over bumps. This mini pack replaces that leaf with a progressive overload, so the spring rate builds gradually instead of all at once. The result is a better ride quality without losing the support you count on when the truck is working. It also gives you rear lift at the same time, from 1\/2 inch up to 1-1\/4 inches depending on how many spacer blocks you run. That means you can level out a nose high stance or add a little height without buying a separate lift product. Because the mini pack bolts to your stock spring pack with new center pins that come in the box, you are keeping the factory springs rather than replacing the whole setup. For an older Ram that needs a smoother ride and a touch more height, this is a straightforward way to get both with one product.\u003c\/p\u003e\n\u003ch4\u003eProgressive Overload Mini Pack Built To Bolt Onto Stock Springs\u003c\/h4\u003e\n\u003cp\u003eThe Cognito 215-91287 Leaf Spring Mini Pack Kit is engineered for 2003-2013 RAM 2500 trucks and 2003-2025 RAM 3500 trucks. It is a replacement for the OEM bottom overload leaf and converts the stock leaf pack from a 2 stage design to a progressive leaf pack. The factory overload spring has a very harsh spring rate, while this mini pack uses a progressive overload that gives a better ride quality. Rear lift ranges from 1\/2 inch to 1-1\/4 inches, set in 3\/8 inch increments with removable spacers, depending on how many spacer blocks are used. These mini packs are only compatible with the stock spring packs, and they fasten to the stock pack using new center pins that are included in the kit.
