This replacement front upper suspension arm is an RC-scale component machined from 7075-T6 aluminum and finished with an anodized surface treatment to guard against wear. It is supplied as a direct-fit replacement for the factory front upper arm location on the ARRMA 1/16 MINI KRATON 3S platforms listed below.
The higher-strength alloy reduces flex relative to standard plastic arms, helping the suspension preserve intended geometry under load and influencing camber and toe behavior during demanding off-road use. It supersedes factory part ARA-2674 and is provided as a pair to replace both front upper arms.
Opt for these arms when seeking a durable front upper arm substitute that maintains OE geometry while lowering flex under higher load conditions.
