NOTE: Due to the difficulty in sourcing pinion flanges (FR3Z-4851-B) we've decided to remove them from the kit. The pinion flange is only recommended for vehicles that are swapping over from an automatic transmission.

INSTALLATION NOTE: When Installing LPX/LPXHD clutch, DO NOT use any assembly lubricant on the splines of the input shaft.
