TRZ Motorsports GM Billet Spindle Mount Spindles - 1" Drop (2014 - 2019 C7 Corvette) - 407-326K
Billet Spindle-Mount Drag Spindles for 2014 - 2019 C7 Corvette
The TRZ Motorsports GM Billet Spindle Mount Spindles are purpose-built for serious drag racers running spindle-mount wheels on the C7 Corvette platform. These lightweight, CNC-machined billet aluminum spindles eliminate heavy hubs and are engineered to deliver maximum strength, precision, and weight reduction where it counts most.
Designed specifically for spindle-mount drag brake setups, these spindles pull each front wheel in by 3/4" to 1" per side (depending on previous brake configuration). Standard construction includes a billet-aluminum body and heat-treated stainless steel spindle pins, with an optional upgrade to titanium spindle pins (Part #32601-TI) that remove nearly one pound of rotating weight.
Each set includes castle nuts, keyed washers, ARP stainless caliper bolts, steering arm bolts, and cotter pins. These must be used with TRZ Billet Steering Arms (303) or the Quick Steer Arms (303-QS) which can improve turning radius by up to 30% on rack and pinion configurations.
These 1" drop spindles are designed for drag race applications only and work with both spindle-mount and hub-style aftermarket brake systems from Strange and TBM.
