Pro-Coil Rear Shock Kit Double Adj. 175# C/O

The Pro-Coil Rear Shock Kit Double Adj. 175# C/O is a premium coil-over suspension upgrade designed for street and performance driving on classic GM A-Body vehicles from 1964 to 1972. This dual-adjustable shock system addresses the demands of enthusiasts seeking improved handling, reduced body roll, and precise ride quality tuning without sacrificing comfort or drivability. Built by QA1, a leader in suspension engineering, this rear shock kit transforms the driving experience by replacing worn factory components with modern, performance-grade hardware.

The kit features a twin-tube design that separates the pressure and working chambers, allowing independent control of compression and rebound damping—the hallmark of double-adjustable shocks. The 175 lb/in spring rate is calibrated for typical street-weight A-Bodies, providing a balanced platform that absorbs road imperfections while maintaining responsiveness through corners. Dual adjustability enables tuning of both compression (bump) and rebound settings, allowing drivers to dial in ride height, stiffness, and handling characteristics to match their specific chassis setup, driving style, and road conditions. The supplied pair covers the rear axle completely, ensuring consistent performance across both sides.

This shock kit is ideal for owners of 1964–1972 Chevrolet Chevelle, Pontiac GTO, Oldsmobile Cutlass, and Buick Skylark models seeking OE-fitment suspension upgrades. Installation integrates directly with factory mounting points, minimizing fabrication and ensuring reliable geometry retention. The 23.13 lb weight and compact profile (10.25 × 8.95 × 21.25 inches) facilitate straightforward fitment without clearance conflicts. Enthusiasts pursuing autocross competition, weekend cruising, or daily driving will benefit from the adjustability and performance gains this pro-grade coil-over system delivers.
