GPM Racing 7075 Alloy Front Steering Blocks (Larger Outer Bearings) for Arrma 1/7 Mojave 6S 4x4 RTR Brushless Desert Truck (MJ3021)

Front steering blocks for Mojave 6S EXB V3

This aftermarket front steering block set is a direct upgrade for ARRMA Mojave 6S EXB V3 platforms, manufactured from 7075-T6 aluminium to improve dimensional stability and bearing alignment. The design keeps RC-scale fitment in mind and replaces factory part ARA-4289 while preserving the same inner bearing size for compatibility with stock hubs.

Key technical changes are limited and verifiable: inner bearings remain 15x24x5mm, outer bearings are upsized to 8x19x6mm (stock 8x16x5mm), and the blocks include multiple tie rod mounting holes to let you tune steering geometry without additional machining. All hardware supplied is high-strength grade 12.9 where noted, and the hub nuts are anodized red aluminium.

Installation notes: the parts ship pre-assembled for convenience, but it is recommended to use a medium-strength screw adhesive on suspension fasteners to reduce the risk of loosening under desert truck loads. Check bearing preload and steering free-play after fitting the larger outer bearings, and verify tie rod lengths match your desired toe and Ackermann settings before final tightening.
