    Minimize Wheel Hop. If you drive your 2015-2019 Mustang like you stole it, you have probably noticed unwanted wheel hop under quick acceleration. This wheel hop is caused by the deflection of the soft, pliable rubber bushings installed in the IRS differential at the factory. A BMR Suspension IRS Differential Bushing Kit replaces those stock bushings with two piece polyurethane bushings to significantly reduce differential deflection and movement. A BMR Suspension IRS Differential Polyurethane Bushing Kit is a great choice for street, performance and race drivers looking to reduce unnecessary wheel hop and differential deflection in the pursuit of better traction and handling performance.

    Superior Quality. BMR proudly designs and manufactures their IRS Differential Bushing Kit right here in the USA. BMR IRS Differential Bushings are molded, to strict tolerances, from a high quality 95-durometer polyurethane. Polyurethane is a synthetic polymer material is that much less compliant than the OEM rubber bushings making it perfect for performance applications.

    No Increase in NVH. BMR's IRS Differential Polyurethane Bushing Kit was engineered to reduce bushing and differential deflection with little, to no change in NVH (Noise, Vibration and Harshness). Seeing that there is no noticeable increase in NVH, this BMR IRS Differential Bushing Kit is ideal for street, auto cross and race use.

    Application. This BMR Suspension IRS Differential Polyurethane 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.

      Poly Bushings

      These were such a great buy and I don’t regret getting them. I have these, BMR speherical vertical links, and BMR’s cradle lockout kit. I have absolutely no wheel hop at all. I launched the car the other day at 3k rpm and it felt like the car was on rails. There is a noticeable NVH difference, I can hear my exhaust a bit more in the cabin for some reason and at low speeds I can hear when I put the clutch in and or change gears, it’s not annoying but I could do without it. It may be because I have the performance pack option which comes with a 3.73 rear diff.
