TAMIYA T3-01 Tree Cap Stabilizer With Speedo by GPM T3017A  [T3017A]

Tree cap stabilizer for T3-01

This aluminum tree cap stabilizer with Speedo is an aftermarket replacement designed for the TAMIYA T3-01 scale chassis, supplied by GPM as model T3017A. It is an RC-scale accessory intended to link and steady the front steering shaft to the front damper, reducing lateral play and helping to maintain consistent steering geometry during cornering and setup runs.

The unit includes one tree cap stabilizer with Speedo and one stainless steel round head screw 3x8 for mounting. Installation is straightforward: mount the stabilizer at the tree cap location and secure it with the provided 3x8 screw, ensuring the steering shaft and damper mount align without binding. No additional tools or parts are required beyond a suitable hex driver to tighten the screw to a firm but not over-torqued setting.

In tuning terms this part functions as a chassis refinement item — small position changes and tightening can alter steering feel, return-to-center behaviour, and the interaction between steering input and suspension movement. Use it as part of stepwise setup adjustments: make small changes, test on track, and log results before further changes.
