      Minimize Wheel Hop. If you drive your 2015-2021 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 2021 S550 Mustangs that are equipped with the factory Independent Rear Suspension (IRS), including the V6, EcoBoost, GT and Shelby models.
