ARRMA 29mm Metal RC Differential Case - ARA311061

The ARRMA ARA311061 is a 29mm metal differential case designed as a direct-fit spare part for a range of ARRMA 1/7 and 1/8 scale vehicles. The stock plastic diff case can be a weak point under hard bashing or competitive use, and this metal unit addresses that with increased durability in a critical drivetrain component. It fits multiple ARRMA models across the Kraton, Talion, Notorious, and Infraction lines, making it a straightforward sourcing option when you need to rebuild or restore your differential.
