PRODUCT DESCRIPTION
UMI’s leaf spring and poly shackle kit is a complete, high-performance solution to lower the rear of your 2nd Gen vehicle. These springs are made with high-quality US Steel and feature multi-leaf construction, lowering the car an average of 2" to 2-½" below stock ride height. They bolt directly into the stock location with no modifications required, and the front rubber bushing is pre-installed for convenience. The poly shackle kit replaces the factory bushing with a heavy-duty, high-performance poly bushing and shackle assembly. No additional components are required. 100% Made In USA. Optional Add On: UMI 2627 leaf spring hardware installation kit includes new high-quality polyurethane isolator pads, heavy-duty Made In USA U-bolts, and hardware. Fits stock and UMI applications. Excellent replacement for worn-out isolators and corroded original hardware. This kit features a 175 lb/in rate and is excellent for street, corner carving, and auto-x. Heavy-duty clips and advanced leaf design reduce spring wind-up compared to stock. The springs are built with self-lubricating plastic isolators to reduce friction and provide consistent spring performance. The front bushings are pre-installed. High-performance polyurethane bushings offer good ride quality with a performance improvement over stock rubber. The kit also includes laser-cut heavy-duty shackles with a tough gloss black powder coat. 100% Made In USA.

2nd Gen Camaro VS Firebird Rear Lowering
The iconic 2nd generation Camaro and Firebird sit atop the same chassis but have very distinct body differences. Most noticeable, when lowering a 2nd generation Pontiac Firebird, is the rounder and taller rear tire opening compared to the Camaro's sleeker tapered-off design. This creates the illusion that the Pontiac is higher than the Camaro, and not lowered the same height in the rear.
To fix this visually, we now offer a leaf spring lowering block set, and recommend it for Pontiac models. See below for rear fender comparisons, and before and after the blocks are installed.
