ENJOY THE SULASTIC AND HAVE AN SMOOTHER RIDE.

Owners of pick-up trucks know firsthand how harsh the ride can be in their unloaded trucks. Heck, even with a considerable load in the bed, the ride is still not exactly luxurious. Sulastic Rubber Springs to the rescue! The rubber springs from Sulastic are an elastic suspension that reduces (and in many cases completely removes) the vibration and shock caused by the leaf spring suspension, improving safety and overall handling of the vehicle. Sulastic rubber springs are designed for the specific spring rate, damping, and spring speed of each make and model of truck in order to improve ride quality. Sulastic rubber springs do not affect the load-carrying capacity of the truck, and the ride height will remain within 1/4 inch of stock height.

A. No. The rubber can detach from the metal or get damaged when exposed to temperatures over 250 degrees Fahrenheit.

A. No, the Sulastic won’t affect the load or tow capacity of your truck at all. The product is designed to fit your truck and only helps you with the vibration, balance and the overall driving control.

Q. Does Sulastic offer a long shackle to lower the rear height?

A. Yes, you can lower your truck by installing a Lowering Kit (KA-01, KA-02, KA-03) in combination with the Sulastic shackle (this combination works only in SA-Models) This combination matches the 3" of extension between the bolts provided by the long shackle or up to 1.5” lower at the axle’s center
