Kyosho Inferno MP7.5 Alloy-7075 3mm lower arm lock plate for front gearbox by GPM HMP7508F  [HMP7508F]

Front lower arm lock plate overview

This RC-scale part is a lower arm lock plate designed specifically for the Kyosho Inferno MP7.5 front gearbox area. Machined from Alloy-7075 at a 3mm thickness, it serves as a direct-fit replacement or spare part for the front lower arm mounting on the MP7.5 chassis.

Functionally it stabilises the lower arm pivot area on the front gearbox, helping to reduce local flex where the arm meets the gearbox and preserving alignment under load during on-track setup adjustments. The neutral design focuses on mechanical support rather than altering suspension geometry.

Installation is straightforward for experienced hobbyists: remove the original lower arm lock plate, transfer any existing bushings or hardware, and fasten this plate in place using the stock screws. Use a torque-appropriate hex driver and check fastener tightness after the first runs, as with any metal replacement component.

Notes for tuning: this plate is intended as a rigid replacement around the lower arm mount and should be considered part of a broader setup approach that includes shock valving, spring rates, and arm mounting positions. It is an RC accessory intended for the Kyosho Inferno MP7.5 platform only.
