These air springs install between the frame and your suspension, giving your truck extra support exactly when and where it's needed. Whether you're hauling a heavy trailer, loading up gear for a job site, or prepping for a long road trip, they help keep everything level and under control. You can adjust the air pressure to suit your load, giving you a smoother ride and helping your tires wear more evenly. That added balance isn't just about comfort either, it improves braking, steering, and even keeps your headlights aimed where they should be. What really makes this setup worth it is the peace of mind it brings. You’re not just buying a part, you're making your truck more capable, confident, and ready for whatever’s next.\u003c\/p\u003e\n\u003ch4\u003eEngineered To Handle The Load When The Work Gets Heavy\u003c\/h4\u003e\n\u003cp\u003eThe Ride-Rite system features a double-convoluted air spring design that delivers consistent performance under stress and high load conditions. Rated to support between 3,200 and 5,000 pounds per pair, these air bags provide serious leveling power without modifying your truck’s factory ride height or suspension geometry. Each air spring operates independently, allowing you to correct off-center loads and maintain balance when towing uneven weight or hauling awkward cargo. The springs help reduce inter-leaf friction in your leaf pack, cutting down on wear and extending the life of your suspension. Most kits are bolt-on and use existing holes in your truck’s frame, making installation manageable with basic tools. Once installed, you'll get reduced sag, more stable handling, and better ride quality under load. Firestone also backs these kits with a limited lifetime warranty on the air springs themselves and a two-year warranty on the hardware, giving you added confidence with every mile.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e Universal\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSupports up to 5,000 lbs of load-leveling capacity, does not increase vehicle's max payload or GVWR\u003c\/li\u003e\n\u003cli\u003eDesigned to reduce suspension fatigue and protect leaf springs under heavy load\u003c\/li\u003e\n\u003cli\u003eMost kits are no-drill and use factory frame holes for faster, easier installation\u003c\/li\u003e\n\u003cli\u003eAir pressure can be adjusted manually between 5 and 100 PSI based on load\u003c\/li\u003e\n\u003cli\u003eSprings operate independently for side-to-side load adjustment and balance\u003c\/li\u003e\n\u003cli\u003eHelps prevent bottoming out when towing trailers, campers, or hauling heavy cargo\u003c\/li\u003e\n\u003cli\u003eMaintains level ride height, improving steering, braking, and headlight aim\u003c\/li\u003e\n\u003cli\u003eBuilt with commercial-grade rubber components and tested for long-term durability\u003c\/li\u003e\n\u003cli\u003eCompatible with most aftermarket air compressor kits for in-cab adjustability\u003c\/li\u003e\n\u003cli\u003eCovered by a limited lifetime warranty on air springs and a 2-year warranty on brackets and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Firestone","offers":[{"title":"Default Title","offer_id":49526489219356,"sku":"FIR2071","price":494.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/FIR2071_20_20Ride_20Rite_20Kit_20Fits_2000.jpg?v=1722355651"},{"product_id":"pacbrake-hp10355-silverado-sierra-air-spring-kit-20-22-gm-silverado-sierra-2500-3500hd","title":"PacBrake HP10355 Alpha HD Rear Air Spring Kit | 2020-2022 GM Silverado\/Sierra 2500HD\/3500HD","description":"\u003cp\u003ePacbrake Heavy Duty Rear Air Spring \/ Air Suspension Kit compatible with Chevrolet Silverado \/ GMC Sierra 2500 \/ 3500 trucks.\u003c\/p\u003e\u003cp\u003eHave you ever noticed a difference in ride control when driving empty vs. driving fully loaded?\u003c\/p\u003e\u003cp\u003eYour truck's factory suspension was designed as a compromise between capability and comfort.

The ReadyLift LOGIQ AirIQ SD1 Air Management Package gives you a clean and simple way to manage your air suspension right from your smartphone. Instead of stopping to adjust valves or dealing with bulky controls in the cab, you can fine tune your air pressure through the AirIQ Bluetooth app in seconds. That means you can easily level your truck when you hook up a trailer, load up the bed, or head out on a long trip. The system is factory assembled and tested so you can install it with confidence and know everything is designed to work together. Once installed, the compressor and management system quietly handle the work while you focus on the road ahead. For drivers who want dependable load leveling with modern convenience, this system brings air suspension control into the palm of your hand.\u003c\/p\u003e\n\u003ch4\u003eFactory Assembled Air Management System Built For Reliable Performance\u003c\/h4\u003e\n\u003cp\u003eThe ReadyLift 50-41100 AirIQ SD1 package is designed to deliver dependable air management through a compact and well organized system. At the center of the setup is the LOGIQ 275SD compressor which provides up to 150 PSI of air pressure with an output of 2.03 CFM at 0 PSI. The compressor operates on a 12 volt electrical system and features a 25 percent duty cycle at 100 PSI, making it well suited for maintaining air pressure in helper bag systems. A single channel control system manages both air springs together in a parallel configuration, allowing balanced pressure adjustments through the AirIQ Bluetooth mobile app. The package arrives pre assembled with a 20 foot wiring harness already installed, reducing installation time and simplifying the process. Included frame mounting brackets allow the system to be securely installed on a variety of truck frames. The kit also includes air line, tee fittings, wiring protection, and fuse taps to support a clean installation. With IP rated components designed to resist moisture and debris, the system is built to perform reliably in real world driving conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e Universal\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal air management system for air springs\u003c\/li\u003e\n\u003cli\u003eDesigned for load leveling air bag setups\u003c\/li\u003e\n\u003cli\u003eControls both air springs together\u003c\/li\u003e\n\u003cli\u003eBluetooth control requires AirIQ mobile app\u003c\/li\u003e\n\u003cli\u003eStandard duty compressor included in kit\u003c\/li\u003e\n\u003cli\u003e25 percent duty cycle compressor rating\u003c\/li\u003e\n\u003cli\u003ePre assembled system simplifies installation\u003c\/li\u003e\n\u003cli\u003eIncludes wiring harness and plumbing components\u003c\/li\u003e\n\u003cli\u003eRequires 12 volt electrical system\u003c\/li\u003e\n\u003cli\u003eFrame mounting space required for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/prod-da.s3.us-east-2.amazonaws.com\/T00494\/aabd5416e3fc53a14f66670adabdd19e.pdf\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"ReadyLift Air","offers":[{"title":"Default Title","offer_id":53978444464412,"sku":"RLA50-41100","price":799.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/50-41100-WEBSQUARE.webp?v=1773436757"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/collections\/GM_Duramax_Air_Springs_Thumb_1.jpg?v=1728503242","url":"https:\/\/www.alligatorperformance.com\/collections\/2020-2026-gm-duramax-66l-l5p-air-springs.oembed","provider":"Alligator Performance","version":"1.0","type":"link"}
