Zone Offroad 3" Adventure Series UCA Lift System 20-23 GM 2500HD / 3500 2020-2023 6.6L GM Duramax L5P 4x4

Bring your HD Duramax to new heights with this complete suspension system from Zone! This 3" Adventure Series Suspension System is built around a set of massive boxed steel upper control arms, along with traditional torsion key technology in order to gain 3" of lift. By using the fabricated arms, equipped with factory style ball joints and rubber bushings, the system is able to maintain a better quality ride and suspension travel over standard "leveling kits". In addition, a front differential drop is included to keep CV angles within the factory operating range.

Rear 2" blocks bring the rear up to give a very slight tail high stance allowing the truck to be used as it was intended without having a saggy ride. Rounding out the kit are a set of Nitro gas or FOX adventure series IFP gas shocks at all 4 corners for a smooth ride and impressive performance across any terrain.

Shock Options - We offer this kit with several shock options:

No Shocks: If you'd rather supply your own shocks, no problem, we give you this option.
Nitro Series Shocks: Zone Nitro Series shock absorber offers stock-like control and performance with fully displaced valving for improved compression and extension travel. This vehicle specific valving is pressurized with 50 psi nitrogen gas; this gas charge ensures split second response and reduced aeration. Combine these features with the special Fluon-banded piston and this shock is built to perform!
Fox Adventure Series Shocks: Built specifically to compliment your Zone lift kit, FOX's proven damping technology provides a comfortable on-road ride and predictable off-road handling in a variety of conditions. Their monotube design uses an internal floating piston (IFP) to separate the shock oil from the high-pressure, nitrogen-charged gas chamber, preventing oil aeration for fade-free performance in rough terrain.
