8'' MAX3.3 Suspension System W/ Falcon 3.3 Shocks And Fab UCA Arms - 2020-2024 GM Silverado / Sierra 2500HD/3500HD

ReadyLIFT delivers a performance game changer for the popular 2020-2024 Chevy Silverado and GMC Sierra 2500/3500 HD trucks with the release of our new premium 8” MAX3.3 Suspension with 3.3 Falcon shocks. Designed to improve stance, performance, and capability, this kit includes everything necessary to clear larger wheels and tires. With vehicle-specific performance-tuned Falcon dampers on all four corners of our kit, these lift kits provide a better-than-factory feel.  The 8” kit includes a new system that pairs front 3.3 Fast Adjust shocks with rear adjustable piggyback shocks. The new 3.3 Falcon’s are Fast Adjust Dampers offering a wide range of adjustability for specific terrain and/or handling characteristics with two separate knobs to tune to your preference. Falcon Performance Shocks improve performance and comfort regardless of the terrain. The versatility of these systems makes them ideal for daily driving, off-road excursions, and tow/haul duties.

These new kits include laser-cut, fabricated heavy-duty steel cross-members, new cast iron OE-style knuckles with the perfect geometry built-in, torsion arm brackets, taller cast style rear lift blocks, new forged torsion keys with the proper amount of indexing, and the 8” includes our popular fabricated steel upper control arms with corrected ball joint angles. These new torsion bar relocation brackets eliminate the traditional lowering of the torsion bars, which can inhibit ground clearance and help to improve the overall driving experience. Additionally, each kit includes crucial differential drop brackets and CV axle spacers, sway bar end links, bump stop extensions, OE style cast rear lift blocks, heavy-duty steel skid plate, and finally, Falcon shocks. 

- 8" Lift Kit GM HD Trucks

- Heavy-duty fabricated steel components utilizing 3/16″ and 1/4″ steel plate

- Full-coverage differential skid plate constructed from 3/16″ steel plate

- Laser cut, CNC formed heavy-duty front/rear drop crossmembers.

- Allow up to 37x12.50 with a 20×9” with a 0 offset wheel

- Xtreme-Duty fabricated 4130 chromoly steel upper control arms

- 3.3 Fast Adjust Dampers offer a wide range of adjustability for specific terrain and/or handling characteristics with two separate knobs to tune to your preference. 

- 3-Position Fast Adjust Knob for Soft, Custom, and Firm Compression. Soft mode allows a partial bypass of the main piston for a softer ride

- 8-Position Micro Adjust Dial offers refined damping adjustments

- Reservoir design increases nitrogen to oil ratio for consistent damping over wide temperature ranges. 

- Hard Anodized Large Bore 6061-T6 Aluminum Shock Body for impact and corrosion resistance as well as increased oil volume for consistent performance.  

- VOD (Volume Optimized Damping) features a digressive linear piston for quicker ramp-up for reduced body roll and an overall increase in damping to reduce bottom out when pushed to the limit.

- Red Line high VI shock oil for consistent performance across all temperatures from -50F to 450F with anti-wear and lubricity agents. 

NOTE:  Some GM HD trucks equipped with Tow Package may require custom-length U-bolts purchased separately. Custom U-bolt length may vary by vehicle application.  If the ReadyLIFT kit's standard U-bolts are too short, ReadyLIFT recommends locally sourcing custom U-bolts built to each truck's specifications.

38" Maximum tire diameter

38x12.50 for no rub on a 9" wide wheel with 0 offset

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
