MOOG Chassis Products Coil Spring Set P/N:CC621
MOOG Chassis Products CC640 front coil spring set for the 1985-2005 Chevrolet Astro and other vehicles supports the front end and sets the vehicle's ride height.
Worn or sagging coil springs can cause premature tire wear because the front end ends up out of alignment. If you see uneven tire wear, park on level ground with the engine off and compare how high each front corner sits. Alignment and tire problems can have other causes, so find the cause before replacing anything.
It fits the 1985-2005 Chevrolet Astro and the 1985-2005 GMC Safari.
