• 1959-1964 Chevrolet Parkwood (All Trims) - GM B-Body Platform

Fitment Notes

• Rear suspension only. For a complete front and rear coilover conversion, pair with the RideTech front coilover and StrongArm system or the complete system (Part #11060202).
• Some vehicles with two rear upper control arms will require an additional StrongArm - Part #11066698, sold separately.
• Professional installation is strongly recommended for this rear suspension conversion.
• RideTech pre-engineers spring rates specifically for the 1959-1964 B-Body platform using Hyperco springs - no additional spring selection is required.

Features

• HQ Series rear coilovers feature impact forged aluminum bodies and a monotube gas-charged design for superior heat dissipation, fade-free performance, and long service life compared to conventional steel shocks.
• Rebound adjustment knob on each coilover allows easy fine-tuning of rear ride quality and handling without removing the shocks from the vehicle.
• Hyperco coil springs are CNC cold-wound from high-tensile premium steel for a consistent spring rate that resists fatigue and bowing over the life of the suspension.
• Rear upper and lower StrongArms (tubular trailing arms) replace the factory arms with significantly stronger tubular steel construction to improve power transfer to the pavement and resist deflection under hard acceleration.
• Adjustable panhard bar allows precise rear axle centering to correct and maintain proper alignment with the new suspension geometry.
• Complete bolt-in rear system - spring rates and geometry are pre-engineered by RideTech for the 1959-1964 B-Body, eliminating guesswork in component selection.

Product Description

The RideTech 11066210 is the rear CoilOver system for the 1959-1964 Chevrolet GM B-Body platform, covering the Impala, Bel Air, Biscayne, Brookwood, El Camino, Kingswood, Nomad, and Parkwood. Sold as the rear-only companion to the complete 11060202 system, this kit provides everything needed to transform the rear suspension of these classic B-Body cars - HQ Series coilovers, rear upper and lower StrongArms (tubular trailing arms), and an adjustable panhard bar. The HQ Series monotube coilovers use impact forged aluminum bodies with Hyperco CNC cold-wound springs, delivering a consistent spring rate, superior heat dissipation, and fade-free damping performance that far exceeds the factory configuration.

The rear StrongArms replace the factory trailing arms with heavy-duty tubular steel units that add the rigidity needed to handle the power and cornering demands of a lowered, performance-oriented classic. The included adjustable panhard bar allows precise rear axle centering to maintain proper alignment at the lowered ride height. RideTech engineers the spring rates specifically for the 1959-1964 B-Body using Hyperco springs, so there is no guesswork in component matching. Some vehicles with two rear upper control arms will require an additional StrongArm (Part #11066698), sold separately. Backed by RideTech's 1,000,001 mile warranty.
