lock Warranty Information keyboard_arrow_down
- From the 1st of February 2013 the SuperPro warranty becomes a Lifetime Warranty with no exclusions.
This means that if a SuperPro product fails, ever, we will replace the product free of charge.
With SuperPros technical superiority in material, design and manufacture a lifetime warranty with no exclusions for off-road, track and competition use is a guarantee we can make with complete confidence.
Our goal is to make SuperPro the only choice of suspension bushings for repair, off-road and performance applications in the mind of workshops and consumers.
Rear Subframe and Differential Mount Kit 15-17 Mustang GT, V6, EcoBoost
This Rear Subframe Bushing and Differential Mount Kit from SuperPro will provide a significant throttle response and stability upgrade for the 2015-2017 Mustang. With the rear differential and subframe held more securely power can transfer smoothly from the engine to the rear wheels without getting lost along the way, as is the case with the original rubber bushings.
The Soft Spots in your Mustang
The soft rubber bushings that ship out with the IRS Mustang GT, V6, and Ecoboost provide a comfortable ride but begin to fall off in the performance arena with "spirited" driving. Basically, when you mash the go pedal anything that isn't tied down in your suspension and drivetrain is going to move and rubber bushings don't do a very good job of keeping things in place.
When the rear differential moves it's taking some of the energy that the engine is throwing back and can cause rapid gain and loss of traction in the rear wheels (wheel hop). The rear subframe can cause this same issue when it shifts with acceleration and since it holds the rear control arms you can have some alignment issues with the rear wheels. This is especially common with frequent hard launches or sudden braking.
Upgrade your Pony's Rear Suspension
The solution to these problems is a firmer connection between the rear differential, rear subframe, and the chassis, but the downside is that firmer bushings or downright solid aluminum mounts can make road driving unbearably shaky and noisy. So a weekend racing enthusiast who likes to drive on the open road has a hard choice; comfort or performance?
SuperPro has designed a solution to this problem and offer the Rear Subframe and Differential Mount Kit for those who frequently compete at the local track and also commute down I35. This kit replaces all the original rubber mounts in the rear suspension with a combo polyurethane and Polyelast bushings that provide a dramatic increase in immediate power to the wheels and reduces the chance of wheel hop, all without adding noise and vibration to your ride.
For the Racer, and the Rat Race
This kit is perfect for the performance pony enthusiast who doesn't want to compromise the grand touring ability of their Mustang for better track times or visa versa. The key is the Polyelast elastomer compound which shares the vibration absorption properties of rubber but keeps its original shape 15 times longer than your Mustang's original bushings. Combined with polyurethane you have a strong and smooth suspension that will maintain comfort and increase performance.
If you are planning to abuse your car on the track and are worried about the durability of these bushings you can rest easy with SuperPro's lifetime warranty which includes racing applications, and Suspension.com will handle that warranty for you in house should the need ever arise.
