This set of shock shafts is an RC-scale replacement part made for ARRMA Mini Kraton 3S models, supplied by GPM under the MAKMDP code. The shafts are manufactured from 4140 carbon steel and retain the same shaft thickness as the original parts to preserve fit and stroke characteristics on the OEM shocks.
Design notes: the shafts replace the original C-clip retention with an integrated clipless-style profile intended to reduce the risk of the clip coming loose while maintaining the same compression travel. These shafts are intended for use with the original ARRMA shock assemblies and are not suitable for GPM shock assemblies.
Installation and tuning role: swap the shafts into the stock ARRMA shock bodies following standard shock disassembly procedures, keeping seals and oil condition consistent with your current setup. Because the shaft diameter matches the original specification, you can expect unchanged piston fit and predictable damping behaviour, which helps when tuning spring rates or oil viscosity for track or backyard running.
Contents and references: set includes shock shaft - 4 pcs. Original part numbers referenced by the supplier are ARA-2670, ARA-2671, ARA-2762.
