ARRMA MINI KRATON 3S Rear Upper Suspension Arms 7075-T6 MAKM057 by GPM  [MAKM057]

Rear upper suspension arm for MINI KRATON 3S

This aftermarket rear upper suspension arm set is a direct-fit upgrade for ARRMA 1/16 MINI KRATON 3S platforms that require stronger, more durable linkages. Machined from 7075-T6 aluminum and anodized for corrosion resistance, the parts are intended to resist deformation during aggressive RC use while preserving factory mounting geometry.

Functionally these arms replace the factory ARA-2675 rear upper suspension arms and use the same ball stud and hinge pin locations, so installation typically requires only the original hardware. The stiffer alloy helps reduce flex under heavy cornering or jump landings, offering a clearer feedback path for tuning spring and damper settings without altering suspension geometry.

The product is supplied as a matched pair and is suited to 1/16 scale brushless 4x4 speed trucks where serviceability and repeatable response are priorities. Routine maintenance is the same as for stock plastic arms, inspect for play at pivot points and keep mounting hardware torqued to factory recommendations.

A practical aluminum replacement for ARRMA MINI KRATON 3S rear upper arms, intended to extend service life and support setup adjustments without changing chassis geometry.
