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

ARRMA 135mm Rear Shock Overview

This MNV6135R rear shock is an aluminium aftermarket unit for ARRMA 1/8 scale platforms that require a 135mm centre distance. It is offered as a direct replacement for the listed ARRMA factory references and is focused on increased shaft stiffness, firmer prefill damping and a heavier spring option to change rebound and handling.

Key hardware details from the product notes: the body is aluminium 6061-T6, the shock centre distance measures 135mm, and the shock shaft diameter has been increased to 6.0mm from the quoted original 4.0mm. Units are prefilled with 1000cSt silicone oil for firmer rebound, and the fitted spring has a wire diameter of 1.9mm with additional 1.7mm black springs supplied for tuning swaps.

Installation follows standard threaded-top shock practice on 1/8 scale RTR trucks: confirm your shock eye spacing is 135mm before fitting, swap top or bottom mounts for orientation if required, and apply medium-strength screw glue where the manufacturer recommends to help prevent fastener loosening under high-impact runs. Parts arrive pre-assembled but check fastener torque and spring preload before the first outing.

For drivers who want a firmer rear end and greater durability on 1/8 ARRMA platforms, this aluminium shock provides a straightforward swap with heavier damping and alternate spring options; confirm mounting dimensions and start with a conservative preload, then tune rebound and spring choice to suit surface and load.
