Renton Coil Spring

The performance advantages of titanium springs extend beyond the 30 to 50% weight savings over steel springs. Advanced data recovery systems have shown that titanium springs enhance shock performance and wheel control through improved dynamic response. This is a result of the reduced mass of the titanium springs. Lower mass springs develop less inertia as the suspension is displaced. Less inertia in the spring mass enables the suspension to respond quicker, resulting in improved ground contact, and traction. RCS titanium springs represent the state of art in spring engineering.

To provide the travel, load capacity and durability required in off-road racing, springs are big, really big. Huge travel and energy absorption come at the cost of heavy springs in the critical semi-sprung weight of the suspension system. The heavier the springs, the more opportunity there is to save weight with titanium. The springs for these applications can run to 40 or 50 pounds. Travel is at a premium for these applications.

The spring pictured weighs 22.5 pounds and replaced a steel spring that weighed 43 pounds.That's a total of approximately 80 pounds of semi-sprung weight. The driver reported a very noticeable improvement in the suspension response. These same springs were run three race seasons where before the steel springs were replaced each season.

RCS Titanium Springs are currently found on Class 10, Class 1, and Trophy Truck vehicles in the SCORE Off-Road series. Our Titanium Springs reduced the weight on the Herbst Racing Trophy by almost 100 lbs without sacrificing durability or performance. Our springs thrive on the punishing environment of the Baja 1000.
