## Overview

The Sulastic Shock Absorber Shackles (model SA-06HD) are engineered for rear leaf spring suspensions on 1980-2016 Ford F-350 and 2011-2023 Chevrolet/GMC 3500HD trucks. Featuring advanced rubber springs, they reduce vibrations and shocks by 60-80%, improve vehicle stability by 20-30%, and shorten braking distance by 10-20%, all without sacrificing load or towing capacity. Designed to eliminate road noise and bed bounce, these shackles deliver a quieter, smoother, and safer driving experience 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ works as advertised but no miracle cure
*by K***S on December 15, 2020*

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.

### ⭐⭐⭐⭐⭐ Fantastic!
*by D***N on June 24, 2024*

These work better than I expected. I wasn’t expecting too much of an improvement but to my surprise it reduced the jarring ride in my lifted 1 ton by about 50% if not more. Super easy to install too.

### ⭐⭐⭐⭐⭐ Great product
*by G***E on October 24, 2023*

Really softened up the ride in the f350
