QA1 1988-98 C1500 Rear Coilover Conversion Systems R140-170

QA1's R140-170 is a rear-only coilover conversion for the 1988-98 Chevy/GMC C1500 that QA1 restricts to trucks with the 10-bolt rear differential; it is not built for 12-bolt rear ends. The kit uses a single adjustable coilover with a 170 lbs./in. spring, in gray/silver, over a black powdercoated suspension, for a stated 4 in. to 7 in. drop. What to check before buying Confirm your C1500 carries the 10-bolt differential before ordering, since QA1 states the kit does not fit the 12-bolt version. Beyond that, installation is listed as bolt-on with no welding and no bed removal required. What comes with it An on-car adjustable panhard bar and adjustable lower trailing arms are included along with trailing arm mount braces, all packaged as one kit with mounting hardware; brake components are not part of the package. Will this fit a 12-bolt rear end? No, QA1 lists this kit as compatible with the 10-bolt differential only. Are brake parts included? No, brake components are not part of this kit.
