Description
The Tuff Country 14166 4" Uni-Ball Lift Kit with Upper Control Arms (No Shocks) is a purpose-built suspension upgrade for GM full-size SUVs that transforms your Chevy Suburban into a more capable, ready-for-adventure vehicle. Designed for 2014–2018 4WD models, it delivers a clean, balanced stance without requiring shocks to be included in the kit.

- Strut Spacer Kit: Front-end lift achieved with spacers—no drilling required.

- Tire Compatibility: Supports up to 33" x 12.5" tires for enhanced traction and road presence.
- Wheel Backspacing Requirement: Requires wheels with 4.5" backspacing; factory rims may not clear.
- Shocks Included: Not included in this kit; use compatible shocks at your discretion.
- Warranty & Origin: Proudly made in the USA and backed by a limited lifetime warranty.
This lift kit is built to help you tackle rough roads and light off-road trails with greater ground clearance and a bolder look, while keeping a ride that remains close to stock on daily errands. The Uni-Ball upper control arms help maintain proper alignment as the suspension cycles, and the strut spacers plus rear coil spacers provide a straightforward installation path. With room for larger tires and a durable, USA-made build, the 14166 kit offers a reliable upgrade backed by Tuff Country’s lifetime warranty.
