Product Details
Description
Raise your Chevy Silverado 1500 with confidence using the Tuff Country 14157 4" Lift Kit. This upper control arm and rear block package is designed for 2014–2018 Silverado 1500 and 2014–2018 GMC Sierra 1500 2WD, delivering a balanced lift that clears larger tires while preserving a near-factory ride.
- Lift configuration: 4" front / 2" rear lift with an upper control arm drop / strut spacer kit, engineered to maintain ride quality and alignment potential.
- Comprehensive hardware: Includes upper control arms, rear blocks, U-bolts, mounting hardware, and necessary brackets for a complete installation.
- Shocks not included: This kit is designed to work without replacing shocks or struts unless you choose to upgrade for a different ride feel.
- Rim backspacing requirement: Requires new rims with 4.5" backspacing or less; factory rims will not fit this lift.
- Tire compatibility: Allows use of 33" x 12.5" tires, giving you a more aggressive stance and increased ground clearance.
- Vehicle compatibility: Custom-fit for 2014–2018 Chevy Silverado 1500 2WD with Aluminum OE Arms or stamped two-piece steel OE arms; also suitable for 2014–2018 GMC Sierra 1500 2WD. Not compatible with Magnetic Ride Control or Air Suspension.
- Installation notes: No drilling required to install, helping keep the process straightforward for qualified installers.
- Warranty and origin: Proudly made in the USA and backed by a limited lifetime warranty, reflecting Tuff Country’s commitment to long-term durability.
This kit is a practical choice for Silverado 1500 and Sierra 1500 owners who want a taller stance and space for larger tires without jumping to a full suspension overhaul. The 4" front and 2" rear lift, combined with the upper control arm drop, helps improve ground clearance, approach/departure angles, and the rugged look you want—while aiming to preserve a comfortable, nearly factory-like ride. Plan for a rim upgrade (4.5" backspacing or less) to achieve proper fitment and performance, and rest easy knowing you have a trusted, US-made product with long-term support from Tuff Country.
