UMI’s 4th Gen F-body competition coilover package is designed for optimal performance. The complete system includes 4 coilover shocks, 4 springs with the appropriate spring rate, fabricated bolt-in mounting brackets and hardware, thrust bearings for each shock, and a spanner wrench for height adjustments.
This package features Viking Triple Adjustable Crusader shocks, with 600 lb/in front and 200 lb/in rear spring rates. It has been tested for road racing, auto-x, and street corner carving. UMI's bolt-in double shear brackets on all four corners are competition proven.
The front upper fabricated shock mount eliminates the rust-prone GM rubber shock mount. The double bearing shocks provide crisp response, zero deflection, and high reliability. This set is competition-ready, yet still suitable for street and corner carving.
It is balanced for use with UMI 35mm/22mm sway bars and offers ride height adjustment from stock to 2-1/2” lowering. Rear bump stops are recommended for use with the rear coilover kit, with factory rear rubber bump stops preferred.
Please note that using polyurethane bump stops is not recommended for this kit.

Viking Performance, Inc. specializes in high-performance double adjustable shock absorbers and related products. Founded in 2011 by experienced racing enthusiasts, the company identified a gap in the market for affordable double adjustable shocks, allowing customers to optimize their vehicle's ride quality by independently tuning compression and rebound settings. By focusing solely on these products, Viking keeps prices competitive with single adjustable shocks, offering better performance without unnecessary costs.
Viking conducts all aspects of design, research, and manufacturing in-house, ensuring quick responses to market changes. The company has received prestigious awards like SEMA's Best Engineered Award and has expanded its product line to include various shock types, such as patented race-only Crusader shocks and lightweight aluminum struts. With a commitment to value and quality, Viking aims to provide exceptional products for racing and performance enthusiasts at accessible prices.
