Additionally, installing bearing buddies on drum braked axles is not a good idea. Excess grease contaminates brake shoes rendering them ineffective during a braking event.

Finally, all drop plate assemblies built by Couplemate are 32mm wide. Some narrower plates can twist under extreme loads and cornering. This action stresses u-bolts and other suspension trailers parts like shackles and bearings.
