Truck owners are well aware of the rough ride their heavy duty trucks have, especially when they have an empty bed. However, there is a solution: Sulastic Rubber Spring Shackles. These shackles contain a rubber spring to provide an elastic suspension that effectively minimizes or eliminates the vibrations and sudden shocks caused by leaf springs. By doing so, they also enhance safety and overall handling. Importantly, these rubber springs do not compromise the truck's load-carrying capacity, and the ride height remains nearly the same as the stock height, deviating by no more than a quarter inch. Enjoy a smoother ride and stop your truck from bouncing around by installing Sulastic Rubber Spring Shackles today.

IMPORTANT NOTES:

Please check the space available to install the shackles in your truck. You need 12” for Sulastic model SAJ-03B. See image below.

On the driver's side, it is required to redirect the fuel filler tube. In this case, be sure to add the FUEL HOSE KIT by making the selection above.

Upon installation, the red block is the gauge for calibration. When you adjust the calibration with the long nut, the red block will fall and this indicates your shackle is calibrated for the weight of your chassis cab. You can see more information when you click on the INSTALL INSTRUCTIONS.
