Product Details
Description
Tuff Country 18471 Front 4" Lift Heavy-Duty Leaf Springs deliver a smoother, more capable ride for Chevy and GMC 4WD trucks, Blazers, and Suburbans. This EZ-Ride system is engineered to lift the front end by 4" while maintaining ride quality and durability.
- Lift height: 4" front lift to increase ground clearance and improve approach/departure angles for larger tires.
- EZ-Ride leaf design: tapered, snub rolled, and pre-set leaves engineered for a balanced, comfortable ride in lifted applications.
- Teflon inserts: reduce squeaking and help optimize ride characteristics over varied terrain.
- Includes poly bushings: ready to install with durable bushings included for a proper fit.
- Heavy-duty construction: designed to handle big-block engines and snow-plow use for demanding setups.
- Front springs only: specifically for front-end installation; two springs are typically required per vehicle for most applications.
- Warranty: backed by a limited lifetime warranty on leaf springs for long-term confidence.
- Compatibility note: not compatible with diesel engine models; suitable for 1973–1987 and 1988–1991 Chevy/GMC 4WD trucks, Blazers, Suburbans, and related 4WD platforms with gas engines.
These springs are a purpose-built upgrade for Chevy and GMC 4WD models that see heavy use—whether you’re tackling tough terrain, towing, or supporting heavy loads. The combination of EZ-Ride technology, Teflon inserts, and included bushings translates to a more controlled ride, reduced noise, and reliable performance under load. For optimal results, plan on pairing two springs per vehicle to achieve the full 4" front lift.
