This Aluminum Rear Hub Carrier Set replaces the stock nylon rear hub carriers on HPI BLITZ, Firestorm and E-Firestorm trucks. They are heavy-duty parts that provide the extra strength needed for high performance driving. 0.5 degrees of toe-in is machined into the hubs so you can tune your rear toe angle to 2.5, 3.5 and 4.5 degrees to help dial in the suspension feel to track conditions.

These rear hub carriers are machined from billet aluminum to exact HPI factory dimensions for a perfect fit, anodized, and laser etched for easy identification. Each set includes left and right hubs, high efficiency ball bearings, bearing crush washers, pivot balls, and washers for suspension geometry adjustment.
