## Overview

Sulastic Shock Absorber Shackles (model SA-06) replace traditional rear leaf spring shackles with advanced rubber springs that reduce vibration by 60-80%, improve vehicle stability by 20-30%, and decrease braking distance by up to 20%. Compatible with key Ford, Chevrolet, GMC, and E-350 models from 1980-2023, these shackles deliver a smoother, quieter ride without sacrificing load or towing capacity—perfect for professionals demanding performance and comfort 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: Wasn't easy to install, but works as advertised - Without a lift or high (tall) jackstands, the install was an absolute bitch and a half. But I stuck with it because of the payoff. Took a good day of working on it to get my parts out, grind a little metal to encourage the spring to seat and then pay attention to the number of washers and orientation when putting the new ones in. With all of that said, I've definitively felt a softer ride in my 2500. I take bumps smoother and the road is a little kinder now. Also did Fox 2.0 all the way around afterwards, and I ride like a new 1500 now. Very satisfied. Let's hope they last a while.
Review: Fixed rear end bucking - Definitely worth the price! I have a 12” lifted superduty and the rear end is way too stiff and these work so well! Had a bad rear and buck on the freeway and this is the problem solver

### ⭐⭐⭐⭐⭐ These are a perfect item for HD suspension.
*by R***N on June 2, 2025*

These are an absolute game changer! They seem a little pricey but believe me they are worth every penny. These were my 2nd set. Installation is a little difficult without a lift but my daughter helped me and it was 3 hours. GMC 2025 AT4x HD 2500.
