Energy Suspension Differential Bushings

Improving Your Vehicle's Reaction Time

Responsible for distributing engine power to the wheels, your differential is crucial to your vehicle's ability to respond to braking or accelerating. However, another part that impacts your differential's performance are the bushings that mount it to the frame. These OE bushings are commonly made of rubber, a material prone to flexing and wear. When these bushings flex your differential is allowed to shift, reducing it's effectiveness.

Energy Suspension makes all of their differential bushings with Hyperflex polyurethane. This polyurethane is much sturdier than rubber, easily able to resist physical wear and road contamination. The increased sturdiness includes added firmness. This firmness allows Energy's differential bushings to maintain a better hold on the differential, enhancing your vehicle's response time. Plus, Energy Suspension covers all of their differential bushings with a two-year warranty handled in-house here at DST.

starstarstarstarstar" Review 2 Years Later "

Photo of part purchased was not what I received. Part had no grease fittings installed. (?). Had to buy, drill part, then install which wasnt very easy to do. Cost me more than it should have. Never again. You didnt have part I ordered. Who would buy this without fittings? Editors Note: The kit 4.3129 does not show a grease fitting. These are polyurethane bushings and are not grease-able. They must be greased using Formula 5 grease when they are installed.

Easy to install, taught my 16 year old to remove old parts and install new parts. I showed him one and he was able to do the rest on his mustang. Great parts.
