HPI 86715 Aluminium Pinion/Clutch Mount for Baja 5B

The HPI Heavy Duty Aluminium Pinion/Clutch Mount (HPI-86715) is a machined alloy upgrade for HPI Baja 1/5th scale vehicles. Designed as an authentic HPI bolt-in part built to factory specifications, it provides a precise fit and added rigidity where it matters most.

Machined from billet aluminium and finished in gunmetal anodising, this mount increases support for the pinion gear and clutch to help improve durability and extend gear life. It includes two rubber sealed ball bearings (B097) with a larger outside diameter for enhanced efficiency and long service life. This part replaces the stock nylon mount (#85436) for a tougher, longer-lasting solution.
