ARRMA KRATON 6S EXB Front Steering Block 7075 Alloy Upgrade - MKV6021 by GPM  [MKV6021]

Replacement front steering block for ARRMA KRATON 6S EXB

This aftermarket front steering block from GPM is CNC machined from 7075-T6 aluminum for ARRMA KRATON 6S EXB 1/8 scale trucks and compatible units listed below. It replaces factory ARA-1507 and is engineered to tighten bearing fit and refine steering geometry by using a machined alloy body and larger outer bearings while keeping the original inner bearing form factor.

Key mechanical details supplied with the part include an inner bearing that matches the original 15x24x5mm and an oversized outer bearing 8x19x6mm replacing the stock 8x16x5mm, plus aluminum front hub nuts in red. All hardware and subcomponents arrive pre-assembled, and the maker recommends medium-strength thread adhesive on fasteners to reduce the chance of loosening under high loads.

Choose this alloy steering block when you need a direct replacement for ARA-1507 with tighter bearing clearance and the option to run larger outer bearings for crisper steering. Confirm fit on your chassis before final assembly, apply medium-strength screw glue where suggested, and check all pre-assembled hardware is secure prior to running.
