Technical Performance
The Fastrax Tamiya TD4 Aluminium Rocker Arms represent a significant performance upgrade for anyone running a TD4 platform RC crawler. Aluminium's superior strength-to-weight ratio compared to plastic means you get improved suspension geometry maintenance under load without adding unnecessary weight to your vehicle. These rocker arms are critical suspension components that directly influence how your crawler responds to terrain changes, obstacle impacts and weight transfer during cornering and climbing. The rigid aluminium construction ensures minimal flex during aggressive driving, maintaining consistent suspension geometry and improving overall vehicle handling. For UK-based RC enthusiasts tackling challenging terrain in forests, on moorlands, or in indoor clay courses, the enhanced durability of aluminium rocker arms translates to fewer mid-session breakdowns and extended periods of reliable operation. The precision manufacturing guarantees smooth articulation without binding, which is essential for crawlers that rely on suspension flexibility to navigate technical obstacles. Whether you're upgrading an aging TD4 or building a fresh competition setup, these rocker arms provide the engineering quality that discerning RC car drivers expect from Fastrax.

Frequently Asked Questions
- Are these rocker arms a worthwhile upgrade for my Tamiya TD4? — Yes, upgrading from plastic to aluminium rocker arms is one of the most practical suspension modifications you can make. Aluminium offers superior strength and durability, reducing the likelihood of breakage during demanding driving. If you're finding that your plastic rocker arms flex excessively or crack frequently, this upgrade will dramatically improve reliability and handling consistency.
- Will these fit my standard Tamiya TD4? — These rocker arms are engineered specifically for Tamiya TD4 crawlers and will fit without modification. However, if you have modifications to your chassis or suspension, we recommend double-checking compatibility with the manufacturer's specifications before purchasing.
- How do aluminium rocker arms improve suspension performance? — Plastic rocker arms flex under load, which causes the suspension geometry to change during cornering and climbing. Aluminium's superior rigidity maintains consistent geometry, improving steering response and handling predictability. This is particularly noticeable on technical terrain where precise suspension control is essential.
- What tools do I need to install these rocker arms? — Installation requires basic RC tools including hex wrenches and screwdrivers. If you're comfortable with basic RC maintenance, installation should take 15-30 minutes per side. Consult your Tamiya TD4 manual for the specific torque specifications and installation sequence.
- How do these compare to other aftermarket rocker arm options? — Fastrax is a recognised brand in the RC community known for quality construction and precise engineering. These rocker arms offer excellent value, delivering the durability and performance of premium components at a competitive price point.
