Details & Inspection Notes
Built around a double adjustable coilover rather than a single adjustable one, QA1's R240-200 gives separate control over compression and rebound on a 1988-98 Chevy/GMC C1500 rear end, running a 200 lbs./in. spring in gray/silver over black powdercoated suspension components.
Fitting it to your truck
This listing does not spell out a particular rear differential requirement the way some of QA1's other C1500 rear kits do, so check your own axle setup against QA1's fitment notes if that distinction matters for you. Air bags are not part of this system, and no welding is listed as required.
What comes with it
The kit bundles an on-car adjustable panhard bar, adjustable lower trailing arms, and trailing arm mount braces with full mounting hardware, sold as a bolt-on kit.
Can I fine-tune the ride beyond just height? Yes, the double adjustable coilover allows separate compression and rebound adjustment, which a single adjustable shock does not offer.
Are air bags part of this kit? No, this system does not include air bags.
