The GPM MGO021 front steering blocks are CNC machined from 7075 aluminium to provide increased stiffness and dimensional accuracy for the ARRMA GORGON 4X2 Mega 550. These components are intended to reduce chassis flex at the front end and preserve CVD geometry under load. Fitting larger inner bearings lowers rotational friction in the CVD assembly, improving response repeatability and reducing wear on mating parts.
