ARRMA MINI KRATON 3S Rear Upper Arm Set 7075-T6 MAKM057 by GPM  [MAKM057]

Reinforced rear upper arm set for MINI KRATON 3S

This aftermarket rear upper suspension arm set is a direct-fit replacement for ARRMA 1/16 MINI KRATON 3S platforms requiring tougher rear linkages. CNC-machined from 7075-T6 aluminum and anodized, the arms are made to withstand repeated impacts while preserving original mounting locations.

They replace the factory ARA-2675 upper arms and keep the same ball stud and hinge pin spacing, so most installations reuse the stock hardware. Stiffer alloy construction reduces unwanted flex during aggressive driving, allowing more precise adjustments to shock and spring setups without shifting geometry.

The pair is aimed at 1/16 scale brushless 4x4 speed trucks where consistent handling and easy servicing are key. Maintain them as you would OEM arms: inspect pivot bearings, look for corrosion, and ensure fasteners are correctly torqued to prevent looseness.

A practical alloy replacement that aims to extend component life and support consistent setup adjustments without changing the MINI KRATON 3S chassis geometry.
