TD4 Aluminum Rocker Arms, RC chassis upgrade

The TD4 Aluminum Rocker Arms set adds a focused suspension upgrade for TD4 chassis cars with 2 blue anodized aluminum parts and integrated ball bearings. Designed as left and right matching components, these rocker arms take the place of the kit-standard C5 parts and give the damper linkage a more exact, controlled feel during running. Each L-shaped arm uses a reinforced profile with a rounded outer corner and a bearing-supported pivot area, so movement through the suspension stroke stays clean and mechanically direct. The aluminum construction changes the character of this section compared with the standard resin part, while the anodized finish gives the pair the familiar Tamiya blue look. Because the set is dedicated to the TD4 platform, fit stays specific to that chassis layout rather than acting as a universal add-on. For tuning sessions, maintenance work or a step-by-step chassis build, this pair suits drivers who want to refine one section at a time. The set contains 2 rocker arms, one for each side, and 2 sets are required to fully kit out the chassis. That makes it suitable both for replacing a single axle pair and for planning a complete chassis conversion with matching hardware across the suspension system.
