Pro-Rear Coilover Kit Double Adjustable

The Pro-Rear Coilover Kit Double Adjustable by QA1 is a premium suspension solution engineered for vehicles requiring independent rear damping control and ride height adjustment. Designed for vehicles in the 1,301–1,500 lb weight range per axle, this twin-tube coilover system addresses the need for tunable suspension in street, road course, and autocross applications where factory geometry and stiffness cannot meet performance demands. Whether you're optimizing handling balance, reducing body roll, or fine-tuning ride comfort, a double-adjustable rear coilover kit gives enthusiasts and professional drivers the precision necessary to extract maximum performance from their chassis.

This kit features QA1's proven twin-tube shock construction paired with a 130 lb/in progressive spring rate, delivering responsive damping across both compression and rebound circuits. Double-adjustable technology allows independent tuning of compression and rebound characteristics without removing the coilover from the vehicle, enabling real-time suspension refinement at the track or street. The vertically compact design (40.5 inches overall length) accommodates typical rear suspension geometries while the modular 8.25 x 8.25-inch footprint ensures straightforward packaging. Twin-tube construction provides superior heat dissipation during extended driving, maintaining consistent damping performance even under demanding conditions.

This rear kit is ideal for vehicles undergoing comprehensive suspension upgrades, track-focused builds, and performance setups where front coilovers have already been installed. The 130 lb/in spring rate complements most street-to-sport applications and integrates seamlessly into systems paired with matching QA1 front kits. Professional installation is recommended to ensure correct ride height, alignment, and damper adjustment settings. Verify your vehicle's rear axle weight rating and suspension mounting points before ordering to confirm compatibility with this 1,301–1,500 lb per axle specification.
