      Eliminates IRS Differential Deflection. Wheel hop is bad, it's that simple. If you can't hook up off the line you're going nowhere fast. Serious drag racers know that the Independent Rear Suspension (IRS) differential of the S550 Mustang is notorious for deflecting under rapid acceleration do to its soft, pliable, factory rubber bushings. A BMR Suspension IRS Differential Bushing Kit replaces those stock OEM bushings with solid aluminum two piece bushings to eliminate differential deflection. BMR's IRS Differential Aluminum Bushing Kit is the ideal answer for drag racers looking to eliminate deflection and significantly reduce wheel hop in the pursuit of quicker more consistent launches at the strip.

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

      Increase in NVH. Seeing that these BMR IRS Bushings are made from solid aluminum you will feel a significant increase in NVH (Noise, Vibration and Harshness). Because of this increase in NVH, these BMR Suspension Aluminum IRS Differential Bushings are intended for drag race use only.

      Application. This BMR Suspension IRS Differential Aluminum 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. Intended for off-road drag race use only.
