4.1139 | Rear Differential Bushings | Ford Mustang 2015

2015 Mustang IRS only (Except COBRA)

These bushings are both wear and contamination resistant, not to mention much sturdier than the OE rubber.

Energy Suspension's 4.1139

Need to motivate your Mustang?

Do you feel like your Mustang needs a bit more power? While it's certainly capable of launching from those annoying red lights, there just seems to be something missing. This could be your OE rear differential bushings. The OE bushings are made of a soft rubber that's prone to flexing. When these bushings flex it reduces your Mustang's responsiveness, slowing your acceleration and making it take longer to stop. After a while this flexing could also cause the bushings to wear out, leading to even more problems. Before you end up in that situation check out Energy Suspension's solution!

A Durable Enhancement

This is Energy Suspension's 4.1139, a Hyperflex polyurethane set of differential bushings made specifically for the 2015 and newer Ford Mustangs. These bushings are both wear and contamination resistant, not to mention much sturdier than the OE rubber. All of these perks are designed to enhance your Mustang's responsiveness and acceleration while also lasting much longer than before.

Tear up the Track!

Since these bushings are crafted using polyurethane your NVH might increase slightly, but the improved response time, durability, and safety for your other suspension parts are all well worth it. Get your Mustang back on track with the 4.1139's dependability and two-year warranty handled in house here at DST.
