      Description

      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 2015-2020 Mustangs including V6, EcoBoost, GT GT350 and GT500 models.

        Perform but Noisy

        These Polyurethane Differential Bushing Lockouts worked on my 2016, but they are noisy. They are not as noisy as the aluminum version (which I think is better for performance), but they still transfer noise. If you are driving with the revs up, your engine will drown it out. But for common use it amplifies your gear noise from 40mph to 75mph with 55-65mph being most noticeable. Interestingly enough, it does quick almost completely after 75mph. The sounds is similar to the should of a dynamo on a bicycle or the gear sounds on a small tractor, like a Kubota, at about 8mph. If you want the performance, pay a little more for the aluminum ones (although, noisier). If you want performanceand not much noise, do the cradle lockout. Installations is easy and took me less than 2hrs. using a jack and jack-stands.

        Not as advertised

        Yeah I know I got the cheaper one due to the others being out of stock during the time of purchase. The instructions are okay at best. It would be in the best interest of one to watch a video via another vendor. The front bushing bolts are 3mm to short and you can't use the lock washers. That's why you have two install 4 bolts where you remove two in the event the shorter ones back out.

        Good product but installation can be painful

        First of all the product is great, good quality fit and I can feel the difference in tradition right if the bat. Minor nvh but definitely noticeable, you don’t have to try to listen for the noise you will hear it. Now issue, at the rear mounts - no issues, the no relief design slides in with first force. The front mounts are another story, you are better off lowering the entire sub frame. For my 2015 no relief design does not allow the bushing to slide into the gap, it needs to be forced in. Keep this in mind, if you have reliefs in your diff bushing then the fronts will be a pain, even after partially lowering the sub frame( front bolts only) there is very limit d space to line up everything to force the bushing in.

        Feeling the difference...

        Installed these on top of many other suspension mods. Would definitely not consider doing this as a separate install because of all of the sub-frame work. Can definitely feel the difference in traction. Seems to launch easier and there is more grip. Very minor noises but certainly would trade that over the better handling. Installation would have been a lot easier if I had a 22mm ratcheting wrench. Front bolts were a little difficult because of the position of the diff.

        The design with out relief is corrects

        Kelly is completely right. The new bushing don’t have reliefs. You have thread the bolt and it will press in flush. That make a solid and more tight fit. 1- 3.73’s bears make winding nois. 2- you will feel the drive shaft at very low speed when depress the clutch pedal. But... I love everything.... Very solid feeling of the rear end!! More traction Highly recommended!!! Hooo, the installation it is ease if you loose both sides of the IRS at the same time.

        "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.
