ARRMA Mini Kraton 3S 71mm 4140 Steel CVD Shafts MAKM071F/RS for upgrade by GPM  [MAKM071F/RS]

Durability-focused 4140 steel CVDs for Mini Kraton 3S

The MAKM071F/RS front and rear CVD drive shafts are aftermarket replacements made for ARRMA Mini Kraton 3S models. Constructed from 4140 steel with a blackened hardening finish, these 71mm shafts are measured 71mm from pin center to pin center and are designed as direct replacements for factory part ARA-2668. Marketed as RC-scale drivetrain parts for the 1/16 Mini Kraton chassis, they are intended to better resist abrasion in everyday hobby use.

During regular maintenance inspect the hardened finish and contact surfaces for signs of abnormal wear. These steel CVD shafts are chosen to reduce wear rates compared with softer stock components, helping preserve drivetrain geometry over time when used under typical conditions.

For owners prioritising longevity, these 4140 steel shafts are a material upgrade that preserves stock geometry while improving wear resistance.
