    Reduce Wheel Hop. The Independent Rear Suspension (IRS) of your 2015-2019 Mustang allows you to carve corners like a professional, but it is notorious for producing an overwhelming amount of wheel hop under quick acceleration. This is because the IRS differential of the S550 Mustangs come equipped with soft, pliable rubber bushings that allow for excessive deflection. The stock rubber bushings perform well at absorbing the NVH (Noise, Vibration and Harshness) of a daily driven commuter car, but are less than desirable for the spirited Mustang driver. BMR's IRS Differential Bushing Lockout Kit solves this problem by sandwiching the factory bushing between two billet aluminum plates, preventing the bushing from deflecting under load. A BMR Suspension IRS Differential Bushing Lockout Kit is the ideal answer for street, performance and race drivers looking to reduce unnecessary wheel hop and differential deflection in the pursuit of better handling performance.

    Superior Quality. BMR proudly designs and manufactures their IRS Differential Lockout Bushing Kit right here in the USA. BMR CNC-machines their Lockout Bushing Plates from aircraft grade 6061 billet aluminum for superior strength and a precise tight fit. These Bushing Plates are then completed in a durable black anodized finish for aggressive good looks and long lasting corrosion resistance.

    Simple Bolt-On Installation. Installation of the BMR Suspension IRS Differential Bushing Lockout Kit can be completed in under two hours with just basic hand tools. No extra modifications or special tools are needed for a simple bolt-on installation.

    Application. This BMR Suspension IRS Differential Lockout Bushing Kit is designed for use on all 2015 to 2019 S550 Mustangs that are equipped with the factory Independent Rear Suspension (IRS), including the V6, EcoBoost, GT and Shelby GT350 models.

      Billet bushing

      Great product! This is for the hardcore Manuel guys that like to launch hard off the line. You will have increase in rear end noise on this because it is billet bushing. Afternoon install because I bought the upgraded 12.9 bolt kit.

      Firm, but noisy

      Install was easy. I have this paired with the bmr cradle lockout kit. Almost no wheel hop or drama on launch. Shifts are very firm under acceleration. Low rpm shifts has alot of chatter, nvh at highway speeds is definitely there. I can live with it i guess.

      Piece of mind

      Very easy install and definitely worth it for piece of mind. NHV is more notice but exhaust kills the noise.

      High Quality, perfect fit

      I've built and raced an off-road Mustang for many years and until I purchased these parts, I have not experienced a True "bolt on". Everything requires a little filing, fitting or modification in my past experience. But that is not true with these BMR parts. They installed just as the instructions detailed and fit perfectly. And most importantly, the combination of BMR suspension parts suggested by American Muscle have stopped my rear wheel hop which was becoming a problem since I have a Whipple stage 2 Kit also installed.
