GPM Racing Alloy Front & Rear Upper Arm Bulk - 1PR for Tamiya TT02 (TT2008)

Precision alloy upper arm bulk for TT02 applications

Supplied as 1pr (2 pcs), this alloy front and rear upper arm bulk is intended for the TAMIYA TT02 chassis and replaces the standard plastic bulkheads. The parts provide a firmer anchor for the upper suspension link on both front and rear units, supporting more consistent suspension behaviour.

Engineered to the TT02 mounting pattern, the components are direct-fit hop-ups that preserve original mounting geometry. In practical setup work they help limit movement at the upper link pivot and assist in achieving repeatable suspension settings for testing and competition use.

Install using standard TT02 methods and the chassis hardware where applicable. Inspect and reuse original screws and ball studs if serviceable, avoid over-torquing to protect threads, and verify wheel alignment and link free-play after installation. Routine maintenance includes periodic thread inspection and a re-torque following initial runs.

Is this a direct-fit for stock TT02 mounting points?

Yes, the design follows TT02 mounting positions so it installs without chassis modification on standard layouts; confirm compatibility with any variant-specific features before final assembly.

What should I check after fitting these bulks?

After installation check fastener torque, wheel alignment and link free-play. Re-torque after an initial running period and inspect threads for any signs of wear.

Do these bulks change tuning approach?

They increase stiffness at the upper link anchor which can make suspension adjustments behave more predictably; expect improved repeatability when testing different spring and damper settings. Write Product Review Please sign in your account before you can write any review. Sign In Close
