I am waiting on my DDM works shocks (QA1) w/ glossy red coilovers) to install on my 16 SS SL w/ 33K. There are not a lot of companies that make shocks for SS's. Caution- if you raise the rear end, it will change the camber/caster of the front tires and can cause uneven wear. DDM QA1's shocks have the ability to lower or raise the ride height of your SS. (-1 inch to +2 inches) But be sure to check with whomever you buy yoru shocks to confirm ride height limits. Also, be sure to check warranty and return policy and price comparision. God luck Keep on SLINGIN'
