The SSR-204-40 spring rear solo is a rear coil spring designed for GMC and Chevrolet vehicles, often paired with an air suspension helper kit to support the left or right rear corner. This SSR20440 spring provides a robust replacement option for sagging rear springs on compatible full-size GM trucks and SUVs.

Good To Know
Q: Can this spring be used with my existing air suspension helper kit? A: Yes, the SSR-204-40 is designed to work with air suspension helper kits that fit the rear coil spring pocket, helping to stabilize the load on the left or right side. Confirm that the spring diameter matches your kit's mounting bracket.
Q: Is this spring sold as a single unit or a pair? A: This listing is for one spring (solo), so you will need to order two if you want to replace both the left and right rear springs. Many applications only require one side if the opposite spring is still in good condition.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
