QA1 Rear drop springs for Trailblazer SS (pair)
For 30.5" ride height
QA1 coil springs are designed to withstand the high stress levels of modern suspensions. Made of hi-tensile chrome-silicon wire, these springs require fewer coils, which reduces weight up to 28 percent and increases travel up to 20 percent, compared with conventional springs.
Note: Not to be used with stock shocks.
