Coilover Suspension Systems for ’88-’98

Ridetech recently announced the launch of two new suspension systems for 1988-1998 C1500 pickup trucks. Available in coilover and air ride configurations, both systems replace your truck’s leaf springs with wishbone-link rear suspension and tubular StrongArm front suspension.

The wishbone upper link locates your truck’s axle without the need for a separate Panhard bar and works with two lower links to improve handling, ride quality better than leaf springs. It all bolts to your factory frame by way of a tubular crossmember and heavy-duty C-notches. Ridetech StrongArms and 2-inch drop spindles combined with coilovers or air springs wand a MUSCLEbar front sway bar complete the system.

3500 Swaybar

Designed for ’88-’98 Chevrolet Silverado/Sierra 3/4 Ton (8 lug), 1 Ton & SS 454. One of the most notable but often forgotten improvements you can make to your Sport Truck or SUV is the addition of anti-swaybars. The reduction of the boat-like body roll keeping the body flat in the turns creates a more confident and safe driving experience. Incorporating 30 plus years of design experience, Belltech anti-swaybars are designed to improve handling and steering response by minimizing body roll while not affecting ride quality.
