Bushing Kit Rear Cradle Steel Inserts

The BMR Suspension Bushing Kit Rear Cradle Steel Inserts (BK053) is a direct-fit replacement and reinforcement solution engineered for 2015–2024 Ford Mustang platforms. This kit addresses a critical wear point in the rear cradle assembly, where OEM bushings deteriorate under the stress of high-cornering loads, aggressive launches, and track-duty cycles. By substituting resilient steel inserts for factory elastomer components, owners achieve improved suspension geometry retention and measurably reduced drivetrain compliance.

Steel inserts eliminate the compliance inherent in rubber bushings, translating to sharper throttle response, more predictable weight transfer during braking, and improved axle control during acceleration. The natural finish steel construction resists corrosion when paired with proper maintenance protocols and provides a stiffer bushing interface without introducing excessive vibration transfer into the cabin on street applications. Installation requires standard hand tools and basic suspension access; the kit includes all necessary components for a complete rear cradle bushing replacement on S550 and S650 generation Mustangs.

This upgrade targets serious Mustang enthusiasts pursuing handling refinement, whether on the road course, drag strip, or spirited street driving. Suspension tuners, performance shops, and Mustang owners building out comprehensive chassis upgrades favor BMR's rear cradle kits as a core component in reducing slop and improving suspension feedback. The bushing kit works synergistically with other rear-end geometry corrections and is compatible with both naturally aspirated and forced-induction S550 platforms. Weight is minimal at 1.12 lbs, and the compact footprint (3.25 × 2.25 × 5.75 in) makes logistics straightforward for retailers and installers alike.
