This is a complete rear differential mount kit.  The pinion mounts are a 2 pc design in 93 durometer, the rear mounts feature a folded wing support internal to the Polyurethane for added support.  These are intended for spirited street applications.  For higher hp applications please see our high hp application 

Set includes 2-Bushing sets (6 total) to replace both bushing locations on the rear carrier.  These are complete replacements including:

• 2 ear mounts (pinion) with rest washers for the subframe interface.
• 2 rear diff mounts for TT applications.
• complete replacements so OE cups will need to be completely removed.

These bushings simplify the installation process by adding 2 simple halves for the pinion vs our modular mount that some shops had difficulty installing or orienting the snubber bushing.  We still offer the modular bushing in another listing.
