These bump stop drops extends the amount of available suspension travel, allowing it to compress further for increased wheel travel over any terrain. This kit also gives your air ride equipped suspension more freedom to articulate and flex, enhancing your truck's ability to traverse challenging obstacles such as rocks, ditches, and washes.

The ICON 77202 Front Splash Guard Kit gives 2020-2026 GM Silverado and Sierra 2500HD and 3500HD trucks additional sway bar clearance as the front suspension reaches full droop. Instead of trimming the factory plastic guard to make room, you can replace it with a purpose built solution designed around the clearance needs of these heavy duty trucks. Its rigid aluminum construction is considerably stronger than the original plastic component, making it better suited for demanding suspension setups and regular truck use. The semi gloss black powder coat finish provides corrosion resistance while giving the guard a clean appearance that blends naturally with surrounding components. Additionally, you do not need an ICON suspension system to take advantage of this upgrade because the kit can also be installed on trucks with stock suspension. It is a smart solution for owners who want better clearance and stronger construction without modifying the original splash guard.\u003c\/p\u003e\n\u003ch4\u003eBuilt To Solve A Full Droop Clearance Problem\u003c\/h4\u003e\n\u003cp\u003eICON developed the 77202 Front Splash Guard Kit after identifying potential interference between the sway bar and factory splash guard when increased suspension down travel brings the front end toward full extension. The replacement guard is manufactured from 1\/8 inch aluminum plate, providing a more rigid structure than the factory plastic component. Each piece is CNC laser cut to achieve precise dimensions before being brake formed into its final shape. This construction creates the clearance needed for proper sway bar movement while avoiding the need to trim the original guard. A semi gloss black powder coat finish protects the aluminum and provides a durable surface for use underneath the truck. The kit is designed for 2020-2026 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD applications and can be used with ICON suspension systems or factory suspension configurations.

The 4\" Deaver Leaf Spring Pack provides an effective solution. Cognito's 4\" Deaver Leaf Spring pack reduces rear-end bounce and axle wrap compared to using lift blocks. By utilizing a higher leaf count combined with thinner leaf material, the Deaver Leaf Springs offer a smooth ride quality for both on and off the road. The additional lift gained from the springs can also improve rear suspension sagging while towing. The springs feature military-wrapped eyelets which provides an extra layer of strength and reducing stress during extreme articulation, further enhancing your truck's capability.\u003c\/p\u003e\n\u003ch4\u003eAmerican Made Steel with Diamond-Ends and Military Wrapped Front Eyelets\u003c\/h4\u003e\n\u003cp\u003eDeaver leaf springs are well known for their high-quality USA construction, and their 4\" Leaf Spring Pack is no exception. The Deaver springs are made of high-quality steel with diamond shaped cut ends and anti-friction pads between the leafs to ensure smooth spring operation. Military wraps that form a double wrap are used for the front eyelets, enhancing strength and safety. The leaf pack is secured by the included center pins and retaining clips which assist in holding leaf springs together during abuse.\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 GM Sierra\/Silverado 2500HD\/3500HD 2WD\/4WD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWill not require cutting or welding to install.\u003c\/li\u003e\n\u003cli\u003eProvides 4 inches of rear lift over factory height.\u003c\/li\u003e\n\u003cli\u003eThinner, more numerous leafs improve ride comfort.\u003c\/li\u003e\n\u003cli\u003eMilitary-wrapped eyelets reduce stress under load.\u003c\/li\u003e\n\u003cli\u003eDiamond-cut ends and inserts allow smoother travel.\u003c\/li\u003e\n\u003cli\u003eEliminates axle wrap common with lift blocks.\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty applies to original buyer.\u003c\/li\u003e\n\u003cli\u003eBuilt in the USA using high-quality materials.\u003c\/li\u003e\n\u003cli\u003eFits 2011–2025 Silverado and Sierra 2500\/3500, 2WD and 4WD.\u003c\/li\u003e\n\u003cli\u003eProp 65 warning applies for California residents.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cognito","offers":[{"title":"Default Title","offer_id":49527502143772,"sku":"COG210-91218","price":1649.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/cog210-91218_02.jpg?v=1722352601"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/collections\/GM_Duramax_Lift_Kit_Upgrades_Thumb_1.jpg?v=1728504801","url":"https:\/\/www.alligatorperformance.com\/collections\/2020-2026-gm-duramax-66l-l5p-lift-kit-accessories.oembed","provider":"Alligator Performance","version":"1.0","type":"link"}
