You've outgrown leveling kits and you need a complete, engineered system that works with or without Adaptive Ride Control suspension. The ReadyLIFT 69-39400 replaces the 69-3940 and is the definitive no-cut 4\" SST solution for the T1 GM 1500 platform.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe Result\u003c\/strong\u003e\u003cbr\u003eFour inches of front lift achieved through heavy-duty laser-cut fabricated steel top-mount strut extensions with an offset design that corrects strut and wiper seal angles, paired with CNC-machined billet aluminum pre-load spacers. Three inches of rear lift via OE-style cast iron lift blocks with built-in axle pad locating ears and new longer U-bolts delivers a subtle, aggressive rake that looks purpose-built with the GM body lines. DOM steel tubular upper control arms with optimized ball joint pivot angles and maintenance-free TCT pivot bushings restore proper suspension geometry at the new ride height. ARC Relocation Bracket included for full Adaptive Ride Control compatibility. The 2019–2022 Chevy Silverado clears a 295\/65R20 on a 20x9 0-offset wheel — a genuine 35\" equivalent tire with no trimming required on most tread designs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVerified Fitment (OFAS Standard)\u003c\/strong\u003e\u003cbr\u003e✅ Fits: 2019–2024 Chevrolet Silverado 1500 (with or without ARC)\u003cbr\u003e✅ Fits: 2019–2024 GMC Sierra 1500 (with or without ARC)\u003cbr\u003e❌ Does NOT fit: Trail Boss, ZR2, AT4, or AT4X\u003cbr\u003e❌ Does NOT fit: 2019 Classic body style (LD or Limited — old body)\u003cbr\u003e❌ Does NOT fit: Super Cruise equipped vehicles\u003cbr\u003e❌ Does NOT fit: Single Cab — fitment and drivability not validated by ReadyLIFT\u003cbr\u003e❌ Does NOT fit: Vehicles with mono-leaf rear springs without upgrade — mono-leaf applications require U-bolt kit 67-39530UB (mono-leaf identifiable by round\/circular U-bolt at top of leaf spring)\u003cbr\u003e❌ Note: Late model 2024 and 2025 applications with round U-bolts require U-bolt part number 67-35120UB for compatibility\u003cbr\u003e❌ Note: Use of 4Auto feature is not recommended with this kit\u003cbr\u003e❌ Note: NOT intended for off-road use or abuse\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLift Height\u003c\/td\u003e\n\u003ctd\u003e4.0\" Front \/ 3.0\" Rear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront Components\u003c\/td\u003e\n\u003ctd\u003e2x fabricated steel heavy-duty strut extensions (offset design), 2x CNC billet aluminum spring pre-load spacers, 4x laser cut washers, 2x DOM steel UCAs with HD ball joints \u0026amp; TCT bushings (ARC adaptor included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear Components\u003c\/td\u003e\n\u003ctd\u003e3\" OE-style cast iron lift blocks with axle pad locating ears, new longer U-bolts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eARC Compatibility\u003c\/td\u003e\n\u003ctd\u003eYes — ARC Relocation Bracket included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eNo-cut, bolt-on installation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e69-39400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReplaces\u003c\/td\u003e\n\u003ctd\u003e69-3940\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eReadyLIFT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eWheel \u0026amp; Tire Fitment\u003c\/strong\u003e\u003cbr\u003eMax tire size varies by model year and body style:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003cth\u003eMax Tire\u003c\/th\u003e\n\u003cth\u003eWheel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2019–2022 Chevy Silverado 1500\u003c\/td\u003e\n\u003ctd\u003e295\/65R20\u003c\/td\u003e\n\u003ctd\u003e20x9 0 offset\u003c\/td\u003e\n\u003ctd\u003eSome trimming may be required depending on tread design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2019–2024 GMC Sierra 1500\u003c\/td\u003e\n\u003ctd\u003e295\/55R20\u003c\/td\u003e\n\u003ctd\u003e20x9 0 offset\u003c\/td\u003e\n\u003ctd\u003eFender flare wheel well restrictions apply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2023–2024 Chevy Silverado 1500\u003c\/td\u003e\n\u003ctd\u003e295\/55R20\u003c\/td\u003e\n\u003ctd\u003e20x9 0 offset\u003c\/td\u003e\n\u003ctd\u003eFender flare wheel well restrictions apply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eReadyLIFT wheel and tire fitment recommendations are based on Wheel Pros wheels and Nitto tires. Actual dimensions vary meaningfully by manufacturer — overall diameter, tread width, aspect ratio, and sidewall construction will differ. Every tire and wheel combination must be test fit prior to final installation. Upgrading to heavier 10-ply (Load Range E) all-terrain or mud-terrain tires will noticeably increase suspension stiffness and alter ride harshness compared to factory 6-ply (Load Range C) tires. Consult your local installer for application-specific guidance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; Engineering Notes\u003c\/strong\u003e\u003cbr\u003eThis is a complete no-cut, bolt-on system. A professional 4-wheel alignment is mandatory post-installation to verify torque specs, confirm ride height, and lock in corrected UCA geometry. Verify rear leaf spring type before ordering — mono-leaf applications require the 67-39530UB U-bolt upgrade. Late model 2024 and 2025 trucks with round U-bolts require 67-35120UB. Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including GM Safety Alert Seat, Lane Keep Assist, Forward Collision Alert, and Super Cruise (where equipped) must be checked and recalibrated after installation — note this kit is not compatible with Super Cruise vehicles.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cstrong\u003eEngineering Question:\u003c\/strong\u003e Does your 2019–2024 Silverado or Sierra have mono-leaf rear springs or standard multi-leaf springs? And does your truck have round U-bolts at the top of the leaf spring? Confirm your rear spring configuration and U-bolt style before ordering — mono-leaf and late-model round U-bolt applications require specific U-bolt upgrades not included in the base kit.\u003c\/blockquote\u003e","brand":"ReadyLIFT Suspension","offers":[{"title":"Default Title","offer_id":51631859499329,"sku":"69-39400","price":949.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/69-39400.jpg?v=1776280440","url":"https:\/\/obsidianforgedautosupply.com\/products\/readylift-4-0-sst-lift-kit-silverado-sierra-1500-2019-69-39400","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
