Tamiya 42320 Lightweight Joint Casings - Track Focused Touring Part  [42320]

Reduce Inertia with Tamiya 42320 Aluminium Casings

If you want to tune your touring car for crisper response, the Tamiya 42320 Lightweight Joint Casings are a sensible option. Made from aluminium, these casings replace stock steel components in Double Cardan universal shafts to shave off weight but keep solid mechanical performance.

Performance Gains from Reduced Mass

The set weighs about 1.2 grams per pair, offering approximately 2 grams saved against traditional steel. That lower mass reduces drivetrain inertia, which can enhance acceleration and handling feel on the circuit.

Fitment Advice and Complementary Parts

Intended for touring car chassis using Double Cardan Joint Shafts, these casings fit parts such as 42216 and 42300. For maximum economy, pair them with Tamiya lightweight cross joints (Item 42319).
