Product Description

The Skyjacker YJ45FS is a single front leaf spring built for 1987-1996 Jeep Wrangler YJ owners who demand serious off-road performance from their suspension. Engineered with Skyjacker's Rock Ready Double Military Wrap construction, the main spring eye receives an extra wrap for added strength under extreme articulation and heavy loads - making this spring ideal for rock crawling, trail riding, and competition-level off-road use. The Softride technology built into every leaf delivers a surprisingly smooth ride by tapering each leaf across its full width, allowing the ends to flex more freely and spread the load across the entire pack.

Each spring is shot-peened, pre-cycled, and factory-set before leaving the facility, so installation is straightforward with no break-in period. Note that this listing covers a single spring - two are needed for a complete front installation. A separate spring bushing kit (SE45YJ) is required and not included. Professional installation is recommended. This spring is compatible with the OEM axle when paired with the optional UYJF U-bolt kit.
