Shock absorbers are without a doubt the brains of your suspension. Nothing influences how your car rides and handles more than its shock absorbers. Their primary function is to control the oscillations of your car’s springs thereby keeping your tires in contact with the road. To best accomplish that objective, RideTech shock absorbers utilize monotube design which allows for a larger piston and more precise valving. The design is superior to twin tubes shocks with respect to damping and reliability. These HQ Series Shocks are rebound adjustable shock absorbers and offer exceptional quality thanks to impact-forged, hard-anodized bodies and heavy-duty shafts. They carry an industry-best 1,000,001 mile warranty.
