GPM Racing Alloy Front Adjustable Upper Arm - 1PR for Tamiya TT02 (TT2054)

CNC-grade style adjustable upper arm for TT02

This alloy front adjustable upper arm is an aftermarket replacement engineered for the Tamiya TT02 chassis, providing a stiffer metal alternative to the OEM plastic arm and enabling precise adjustments to front suspension geometry for track-focused setups.

Engineered with multiple mounting locations, the arm allows systematic camber and roll-center adjustments without modifying the bulkhead or uprights, giving tuners repeatable setup options for different surfaces and racing conditions.

Installation follows standard procedure: remove the factory arm, transfer any required pins and hardware, and secure the alloy arm to the stock mounting points. After fitting, perform alignment checks and verify steering travel and clearance across the full range.

Service procedures include routine torque checks on fasteners and inspection of pin interfaces for wear; when fitting different ball studs or turnbuckles, revalidate geometry. The alloy construction reduces flex relative to plastic, resulting in more direct feedback to setup changes.

Specifications

• Item: Front Adjustable Upper Arm
• Material: Alloy
• Model Number: TT2054
• Compatibility: Tamiya TT02 chassis

A precision upgrade for TT02 builders seeking consistent, tuneable front-end characteristics and reduced component flex.

Does the arm require bulkhead changes?

No bulkhead alterations are necessary; the arm is designed to use the existing TT02 mount points while providing alternate pickup positions for tuning.

What should I inspect after installation?

Verify wheel alignment, check that steering linkage does not bind at full lock, and confirm fastener torque across mounting points to ensure stable behavior.

Will this change handling on different surfaces?

Yes. Using different pickup positions alters camber and roll-center, which can be tuned to suit carpet, tarmac, or short club tracks for more predictable handling.

Recommended maintenance intervals?

Inspect mounting hardware and pin bores after intensive track sessions or impacts, and check geometry after any change to turnbuckles or ball studs to maintain setup accuracy. Write Product Review Please sign in your account before you can write any review. Sign In Close
