Your cart is empty.The Sulastic Rubber Spring shackles are designed to replace traditional leaf spring shackles that connect the leaf springs to the hanger. Featuring a large rubber spring, Sulastic effectively reduces vibrations by absorbing suspension deflection and smoothing out the oscillations of the leaf springs. Importantly, this enhancement does not compromise load or towing capacity, as the stop member engages when the vehicle is loaded. This product is available for purchase as a set for the rear axle.

I only leave reviews for something after several months to get a good idea of how well something works. These were recommended as a method to reduce the jarring and to make the ride smoother. After several months, I will attest to these shackles improving the overall ride experience when not towing my 5th wheel. They have been worth the money spent to improve the ride.
