QA1 78-88 GM G-Body Pro Rear Coil-Over System - Single Adj. - 12in x 200lbs/in - Aluminum

QA1 RCK52352 delivers a complete bolt-in rear coil-over conversion for 1978-1988 GM G-Body vehicles including Chevrolet Malibu, Monte Carlo, Buick Regal and Oldsmobile Cutlass. This kit replaces stock suspension with single adjustable aluminum shocks, 12-inch 200 lb/in springs, custom USA-made brackets and hardware for precise handling in street driving, drag racing or autocross. Ride height drops the rear for better traction and cornering while maintaining daily drivability.

Key Features

  • Single Adjustable Shocks: 18 positions of simultaneous rebound and compression damping adjustment to fine-tune response for street or track conditions
  • Fully Threaded Aluminum Body: 12-inch shock length enables easy ride height changes without disassembly, lowering vehicle up to 2-3 inches
  • Custom Bolt-In Brackets: USA-made steel mounts ensure direct fit with all hardware included for 30-minute install per side
  • 200 lb/in Springs: Eibach-rated linear rate handles 3500-4500 lb vehicles from casual cruising to hard launches, multiple rates available
  • Lightweight Design: Billet aluminum shocks reduce unsprung weight by 10 lbs per corner versus OEM for sharper response and dyno-tested performance

Product Notes

  • Later model G-Bodies average 200-400 lbs more curb weight than early models. select spring rate accordingly for balance
  • Kit lowers rear ride height 1.5-3 inches depending on preload. measure before install
  • 100% dyno-tested, serialized shocks are rebuildable at QA1 service centers worldwide

Installation Notes

  • Professional installation recommended.
  • Bolt-on design uses factory locations. no welding or fabrication needed
  • Compatible with stock or aftermarket rear ends including 8.5/8.8-inch 10-bolt or Ford 9-inch
