GPM Racing Alloy Front Knuckle Arm with Bearing - 1PR Set for Tamiya TT02 (TT2021B)

Precision alloy front knuckle for TT02 tuning

The TT2021B alloy front knuckle arm is a precision upgrade designed for Tamiya TT02 steering assemblies. This aftermarket steering hub replaces the original nylon knuckle with a metal unit that locates a bearing at the steering pivot to reduce friction and improve repeatable steering action. The part ships as a 1pr set for hobbyist tuning and maintenance.

Installation notes: retain the original nylon component where specified to preserve the intended geometry. Confirm correct bearing seating and orientation and check steering linkage alignment so the pivot rotates without binding. Use the chassis hardware and adhere to the recommended torque values for final assembly.

Intended as an upgrade component, the alloy knuckle increases front-end stiffness compared with a stock nylon part and positions a bearing at the pivot to reduce wear and drag. Use incremental handling adjustments when testing to evaluate changes in steering feedback and component life.

Select this precision alloy knuckle when seeking firmer steering bearings and reduced pivot friction, and ensure correct fit by retaining the specified original nylon parts during installation.

Is special tooling required to fit the TT2021B knuckle?

No specialised tools are required beyond standard hobby screwdrivers and pliers; ensure you have correct size drivers and a means to verify bearing seating during assembly.

How does the bearing placement improve steering?

Placing a bearing at the steering pivot minimises rotational friction and distributes load more evenly, which reduces wear on mating nylon surfaces and improves repeatable steering feel.

What maintenance does this knuckle require?

Inspect bearing seating and pivot movement periodically, keep the bearing clean and lightly lubricated as needed, and check that the original nylon component used for fitment remains undamaged. Write Product Review Please sign in your account before you can write any review. Sign In Close
