This aluminium rear arm bulk from GPM is produced for the TAMIYA TB-04 chassis and supplied as a 1 set replacement hop-up. As an RC-scale component it focuses on replacing the stock plastic bulk to give a firmer mounting point for the rear arms and related suspension links.
Installation is straightforward for experienced hobbyists: remove the stock rear bulk, transfer any sealed bearings or link hardware, and fasten the aluminium unit using the original mounting points. Basic tools such as a hex driver are sufficient, and attention to fastener torque helps avoid chassis distortion.
In tuning terms this part serves to stabilise rear-end geometry and provide a more consistent platform for suspension adjustments. Expect subtle changes in handling feel as chassis stiffness around the rear arms changes; test incremental settings on the track to establish the preferred balance between responsiveness and traction.
