Product Details
Description
The Tuff Country 18370 Front EZ-Ride Leaf Spring upgrades your GM 4x4 with a true 3-inch front lift, delivering a smoother, quieter ride for daily driving and off-road confidence. Built for Chevy and GMC trucks, Blazers, Suburbans, and similar 4WD models, it adds front-end rigidity and ride quality without sacrificing control.
- Lift Type: Front only, 3-inch lift over factory height for enhanced ground clearance and a more balanced stance on lifted applications.
- EZ-Ride Leaf Technology: Tapered, snub rolled and pre-set leaves designed to smooth out rough roads and uneven terrain for a noticeably calmer ride.
- Teflon Inserts: Integrated to improve ride characteristics while reducing squeaking and noise during regular driving and under load.
- Bushings Included: Poly bushings are included for durable, quiet operation and easier installation with compatible hardware.
- Engine Compatibility: Recommended for small-block engines; not suitable for diesel engine models.
- Quantity and Fitment: Sold individually; two springs are typically required for a complete front suspension upgrade on most applications.
- Warranty: Limited lifetime warranty on the leaf springs, reflecting durability and long-term reliability.
- Vehicle Coverage: Designed to fit front axles on 1973–1991 GM 4WD platforms, including Chevy/GMC Blazer, Suburban, Truck, and Jimmy variants (with non-diesel engines).
