    Features & Details

    • Bushing Lockout Kit
    • Precision Molded from 95-Durometer Polyurethane
    • Absorbs NVH and Improves Throttle and Traction
    • Installs Over Factory Differential Bushings
    • Designed and Made in the USA
    • Non-Permanent Modification
    • Fits 2015-2018 Ford Mustang Models
    Drastically Decreases Differential Movement and NVH. Eliminating NVH (noise, vibration, and harshness) or improving performance — your mustang's stock rubber bushings might make you choose between the two. But with the BMR Polyurethane Differential Bushing Lockout Kit, you can have the best of both worlds. It's designed to limit NVH and lessen differential movement and pinion rise, improving your mustang's handling and rear stability.

    Precision-Molded for an Exact, Perfect Fit. Unlike OE bushings that are made of soft rubber, the differential lockout bushing kit from BMR is made of 95-durometer polyurethane. The material has been precision-molded to exact tolerances, completely filling the space between the bolt and bushing cup and eliminating air pockets or voids that cause excessive differential movement. This reduces wheel hop and improves your mustang's handling stability and performance in any driving condition.

    A Convenient Solution That's Designed and Made in the USA. This differential bushing lockout kit from BMR is a non-permanent modification that installs over your mustang's factory differential bushing — a convenient solution for NVH issues and bushing-deflection. This item has been designed and developed in the USA, ensuring its reliability and durability for both normal and performance driving.

    Application. This BMR Polyurethane Differential Bushing Lockout Kit is designed to fit all 2015-2018 Mustangs including V6, EcoBoost, GT and GT350 models.

      "No-Relief" Design IS CORRECT

      I would like to clarify. I have been using these for several years with great success - and the design does NOT have reliefs as JoeR below mentions. The current design does not have reliefs for the OE bushings - simply press in and start the bolt threads.

      Poor manufacturing

      Very disappointed in the manufacturing of this product. Ordered these some time back, website had them in stock, later find out they were 2-3 week back ordered which turned into 6 weeks. Finally get around to install them and find out the bushing did not come pre notched to accommodate the install over the tabs on the stock rubber bushings. Called AM and they said they said the parts could be returned but are on back order again with no timeframe of getting them in. A friend also purchased them so I called to have him inspect his as he has not installed them yet, they too were manufactured wrong. I ended up taking a grinder to my bushing inserts to notch them myself. With some trial and error I finally got them in. What should have took about 1.5 hours turned into 4 hours. Very disappointed!

      No press, no problem

      The benefit of this is that it firms up the differential bushings without the need for dropping the subframe or a press. Likely not as effective as solid bushing replacements, but for a street car it’s a great compromise. With entirely aftermarket suspension the nvh isn’t noticeable, I doubt it’s all that noticeable even with everything else factory (unless you’re overly sensitive to any kind of communication your car provides to you as a driver). There were extra bolts supplied with the kit that weren’t specifically referenced in the instructions, wish the instructions were a bit more clear on what provided hardware is for, even if that hardware doesn’t apply to all applications. Just for some piece of mind. With the subframe lockout kit, coil overs, verticals links, adjustable camber arms, and toe arms I can’t feel any wheel hop, even on R-compound tires. I have to rely entirely on sound and throttle input to tell when the rear tires are slipping (which isn’t easy with these cars vs. throttle by cable cars). Overall, great product.

      Great product

      Bought these for my car since the driver rear bushing always fails. Installed these and reduced wheel hop and puts less stress on the original bushings. There is a increase in NVH at certain speeds but overall happy with the product and is priced very reasonably!

      Good Kit

      Great product easy to install, except the front because the subframe has to drop

      What's with the noise?!?!?!

      This product is awesome at handling the sloppy acceleration due to the factory rubber soft bushings. Now acceleration is solid and deliberate...just as it should be. Was a pain to install the front driver side, but well worth the 1.5 hours to install.

      Not Recommended for GT PP if Daily Driver

      After installing my car howls loudly under load from 50-80 MPH. The gear wine noise is deafening. BMR claims this is common with GT PP cars due to the 3.73 gears. I had to remove them after 100 miles. Installation is not hard, just time consuming. Especially when doing it twice to remove them. Will work great for a race car. But not for a daily driver. Especially a GT with PP gears.

      Another Great BMR Product!

      The differential lockout kit from BMR can be a bit difficult to install (especially with the upgraded hardware kit), but it makes a good bit of difference for tightening everything up on the rear end. If someone had to drop the entire differential cradle, that would be the time to install them. There is some added gear whine noise with this product at highway speeds, but is to be expected.

      Noisy on PP GT

      These seem like a quality part, but I had a lot of noise after installing. My car howls loudly under load. Contacted BMR and was told this is common with PP cars. The suggestion was the change diff fluids and have gears checked for tolerances or remove them. I think I will probably just remove them. Installation takes some time as you need to drop the exhaust and lower the front of the IRS. Not a hard install, just time consuming.

      Better then before.

      These are the improved diff bushing lockouts from BMR. Much less NVH then previous. still a very involved install.
