ARRMA Notorious 6S Replacement Rear Shock 135mm MNV6135R by GPM  [MNV6135R]

Overview: 135mm ARRMA Rear Damper

The MNV6135R is an aluminium aftermarket rear shock made for ARRMA 1/8 scale platforms that require a 135mm centre distance. It is sold as an alternative to the referenced ARRMA factory units, emphasising increased shaft stiffness, firmer factory prefill damping and a heavier spring choice to influence rebound and vehicle balance.

Core hardware notes: body material is aluminium 6061-T6, shock centre distance is 135mm, and the shaft diameter has been stepped up to 6.0mm from the quoted 4.0mm original. Each unit ships prefilled with 1000cSt silicone oil for firmer rebound, and the fitted spring measures 1.9mm wire with spare 1.7mm black springs included for tuning swaps.

Fitting is typical of threaded-top shock assemblies used on 1/8 RTR trucks: ensure your chassis uses the 135mm eye spacing before installation, exchange top/bottom mounts if needed to suit orientation, and apply medium-strength screw glue where recommended to help prevent loosening under heavy-impact or stunt driving. The parts come pre-assembled but check fastener torque and spring preload before first use.

For hobbyists seeking a firmer rear end and greater durability on 1/8 ARRMA models, this aluminium shock is a direct swap offering firmer damping and alternative spring options; confirm fitment and begin with conservative preload then tune rebound and springs to match surface and payload.
