The polyurethane inserts in the BMR Polyurethane Differential Bushing Lockout Kit simply reduce the bushing deflection. This non-permanent modification keeps the factory bushing in place, so NVH levels are not increased like a solid bushing replacement.

BMR Suspension’s Polyurethane Differential Bushings Lockout Kit (BK) drastically decreases differential movement and pinion rise over the factory rubber bushings. BMR designed its Differential Bushing. BMR Apparel - BMR T-Shirts: Ford Mustangs Mustang Shelby GT Mustang Mustang. - Mustang Differential Mount Bushing Kits BK - Bushing Kit, Differential, Polyurethane - Minimize wheelhop and enhance the rear stability of your and newer S Mustang by decreasing differential movement with polyurethane differential bushings from BMR Suspension.

Polyurethane is a synthetic polymer with many properties that make it far superior to OEM rubber for BMR Suspension.

These bushing is how the upper control arm directly connects to the differential, making it crucial to a proper functioning rear suspension system. Manufactured from multiple durometer polyurethanes, BMR’s EN bushing kit can stand up to high compression loads, while remaining soft enough for suspension articulation. Each piece is made in a precision mold, ensuring every polyurethane bushing fits your S perfectly. BMR. A press is not needed just a few hours of your time.

Polyurethane is a synthetic polymer that has many properties that make it far superior to OEM rubber bushings. Feb 07, I didn't find that the poly bushing made any more noise than the rubber bushing, but I already had been running BMR LCA and UCA with poly bushings.

I heated the inner steel collar of the bushing with a torch to push it out of the bushing and then used the wire brush cup to remove the remainder of the bonded rubber. Jun 01, I would recheck everything and make sure all bots are properly torqued especially on the differential an driveshaft bolts. I will say that I got a lot of gear whine while cruising at highway speeds. Got so annoying I purchased a used subframe on ebay and switched it out.

Also, interesting info, I think BMR discontinued the poly and delrin bushings. Dec 31, I could've also gone w\ the GM bushing removal\installer tool that jewlc75 provided a link to as it was much cheaper than this Rotunda set but I just decided to NOT overthink it & went w\ the right tool set specifically designed for this work on these S's" rear live axle suspensions to replace the modded poly BMR rear axle bushing.
