## Overview

The Sulastic Shock Absorber Shackles (model SA-06HD) are precision-engineered rear leaf spring replacements compatible with 1980-2016 Ford F-350 and 2011-2023 Chevrolet/GMC 3500HD trucks. Featuring a large rubber spring, they reduce vibrations and shocks by 60-80%, improve vehicle stability by 20-30%, and shorten braking distance by 10-20%, all without affecting load or towing capacity. Designed for durability and comfort, they eliminate bed bounce and road noise, delivering a superior ride quality in all weather conditions.

## Description

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.

Review: Better truck - Well fitted and good quality.
Review: works as advertised but no miracle cure - they do work to an extent. they cut out some of the harshness of kidney jarring bumps from my f350 dually. Probably safe to say its a 50-60 percent improvement in ride quality when comparing it to a f250, i have both and my 250 rides like a dream with factory springs and the extra weight of a utility bed, my 350, not so nice! the wifey didnt even want to ride in it until i put the sulastics on, now she says its acceptable and i agree. as a side note i run commercial tires at 100psi so my ride is super harsh anyways. At slow speeds small bumps match the softness of the front suspension, which is a huge improvement , at high speeds you will be reminded that you bought a heavy duty truck! so in summary, the sulastics do work, i wish they were cheaper but these heavy trucks ride like crap and anything helps, they should come factory. i am satisfied and would purchase them again, this application fit a 2011 f350 dually with bed off 900lbs flatbed installed, fit was perfect and raised rear ride height 1/4 inch even with extra weight of flatbed. this was not a chassis cab. its a brilliant concept that works and you will be pleased with the results if you keep your expectations reasonable.
