Superlift 551 4" Rear Coil Spring (Pair) for 97-06 Jeep Wrangler TJ

Superlift coils are manufactured from Spec. 5160 spring steel. Their designs give you the desired ride height increase, with minimal (if any) effect on ride quality. All coils are preset solid (fully compressed and stressed in the manufacturing process) to minimize settling. Coils are either powder coated or vinyl coated in black, depending on application.
