The UMI Performance 2065-1-B Front Weight Jack System is a high-performance coil spring lowering kit designed specifically for 3rd Gen F-Body vehicles. This adjustable system replaces the factory spring with a precision-engineered weight jack bucket and custom-wound 850 lb/in racing spring, delivering 0 to 2-½ inches of lowering capability with independent front corner weight tuning.

Key Features:

• Custom 850 lb/in premium racing spring for optimal performance and daily driving comfort
• Adjustable weight jack bucket with extra-thick ¼" CNC laser-cut USA steel construction
• Acme thread bolt with industry-exclusive thrust bearing system for smooth, easy ride height adjustment
• Anti-rotation tab prevents spring movement under load

The thrust bearing system distributes load over a large surface area while reducing bending potential, making ride height changes at the track quick and effortless. This kit provides coilover-style adjustability while maintaining factory strut clearances for maximum fitment options. Manufactured, tested, and race-proven in the USA for demanding street and track applications.
