ARRMA 1/8 Rear Shock 135mm Compatible with Notorious 6S MNV6135R by GPM  [MNV6135R]

135mm ARRMA Rear Shock Summary

The MNV6135R is an aluminium aftermarket shock intended for ARRMA 1/8 scale vehicles that use a 135mm centre distance. As a drop-in replacement for the referenced ARRMA parts, it prioritises a stiffer shaft, stronger damping from increased oil viscosity, and heavier spring options to tailor rebound and handling.

From the specifications: aluminium 6061-T6 construction, a measured centre distance of 135mm, and a shock shaft diameter increased to 6.0mm versus the quoted 4.0mm original. Shocks are supplied prefilled with 1000cSt silicone oil for firmer rebound response, and the mounted spring is 1.9mm wire with spare 1.7mm black springs included for tuning swaps.

Fitting is standard for threaded-top shocks on 1/8 RTR trucks: confirm the 135mm eye-to-eye spacing before fitting, change top/bottom mounts if you need a specific orientation, and use medium-strength screw glue on small fasteners where recommended to reduce loosening under heavy-impact driving. Units come pre-assembled; verify torque and spring preload prior to the first session.

If you need a firmer rear setup and improved longevity on 1/8 ARRMA machines, this aluminium shock is a practical upgrade; ensure correct wheelbase mounting, start with modest preload, and then test rebound and spring combinations to suit your driving environment.
