      • 5 Piece Bushing
      • Polyurethane Construction
      • Straightforward Installation
      • Improves Straight Line Acceleration Handling
      • Fits all 2005-2014 Mustangs


      Improve Handling. If you're facing inconsistent starts at the track due to wheel hop, consider investing in BMR's Differential Bushing Kit. Unlike your rubber factory bushing, which is designed to flex for the average driving style, this Bushing features a dual durometer design that maintains stiffness inside to better handle straight line acceleration loads. The outside of the bushing remains softer to ensure reliable handling, while preventing binding to maximize your performance on the street and track.

      Durable Construction. This Rear Differential Bushing is proudly made in the USA. It is crafted from high quality, red polyurethane for reliable response and durability, ensuring the performance you seek. This 5 piece bushing includes an inner bushing sleeve and two of each inner and outer polyurethane bushing parts which come together to ensure uncompromising performance.

      Straightforward Installation. This Bushing Kit is specifically made for an easy installation in your factory bushing's outer shell. BMR provides a complete and concise install guide with images. It will direct you in using a hole saw drill bit to remove your factory bushing material and install their custom Polyurethane Bushing in its place.

      Application. The BMR Differential Bushing Kit is designed for 2005 to 2014 Mustang models and will require use of the factory bushing shell for installation.

        Great bushings

        Great bushings well-made Install wasn't too bad. The hardest thing was getting the old bushing out of the sleeve and cleaning it all up with a wire wheel inside. I press the old bushing out. With a Big C clamp and a large Circle socket that fit it over the left side of the bushing on driver side and pressed it out. Worked in great the new bushings were easy to install. A little noisier than the stock. But works in feels a lot stiffer Took about 2 and 1/2 hours to install. Would definitely buy again. Thanks BMR And a.m.

        Works well

        Using a c-clamp to press these in is not practical like the instructions recommend unless you have a lift or the rear end out. Otherwise, fit is tight and eliminated the noise my original was making.

        Definitely Read the Instructions

        Things I learned: -Definitely don't drive out the original bushing in its steel sleeve. You need that sleeve. -Despite appearances, both halves of this bushing get driven through from the driver's side. -Have a LARGE C-Clamp on hand, instead of having to drive across the state in your girlfriend's car at 1am to get one from your parents' house. -Probably don't throw away the instructions. -If you did throw away the instructions, there's a PDF available online, but now your phone/keyboard is covered in silicone grease. Forever.

        Good product, but install was a high level of difficulty. Not recommended for novices or beginners.

        very nice bushings

        replaced my worn diff bushing with the bmr bushings and the rear of the car is definitely more stiff. very little nhv and well worth the money.

        1 2008 GT - Garrett Installation Time: Shop Install

        Tough install

        The product itself looks good but the directions BMR sent with the bushings looks like a copy of a horrible copy, the pics are dark and blurry and the in instructions vague. The fit is questionable to an almost impossible location to get to if you have big arms and a hands. If you need help installing, hopefully you know someone with some experience.

        BMR Differential Bushing

        Works well enough. Much stiffer than the stock bushing. There is no way to lubricate the bushing after assembly. I had the rear end on the bench so the bushing was very easy to install.

      Does this kit cover both ends of the upper control arm or do I need to purchase a control arm too for the upper end?

      Pictures look like they do but does the kit include bushings for both ends if upper control arm or do I need to get a replacement control arm?

      Where could I get the outer bushing shell. Bough the bushing. Now I just need the outer shell.

      If I have an adjustable upper control arm, will this application fit?

      • The BMR Differential Bushing Kit will fit with an adjustable upper control arm mount, you just need to reuse the factory metal bushing shell for install.
