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

Heavy-duty rear upper arms for MINI KRATON 3S

This rear upper suspension arm set is an aluminum direct-fit upgrade for ARRMA 1/16 MINI KRATON 3S, built to strengthen the rear linkage while keeping factory mounting points. Machined from 7075-T6 alloy and anodized to resist corrosion, the components are intended to limit deformation during aggressive off-road running.

These arms are made to replace the factory ARA-2675 rear upper suspension arms and maintain the same ball stud and hinge pin locations, so installation normally uses the original hardware. The stiffer alloy reduces flex under hard cornering and big landings, giving clearer feedback when tuning spring and damper rates without changing suspension geometry.

The kit ships as a matched pair for 1/16 scale brushless 4x4 speed trucks where repeatable response and serviceability matter. Routine care mirrors stock parts: inspect pivot joints for play, watch for corrosion, and keep mounting hardware torqued to chassis specifications.

A straightforward aluminum replacement for ARRMA MINI KRATON 3S rear upper arms that extends service life and supports setup changes without altering chassis geometry.
