Spec-R Tamiya 416 gear diff
New from Spec-R for the Tamiya 416 is this gear differential. Made using a lightweight plastic housing, nylon gears and longlife diff joints, the full set weighs in at only 26 grams and can be reduced further, close to the weight of the original ball diff, if you use the optional aluminium drive cups. Offering amazing forward traction, this a very durable system, with little or no rebuilding necessary and which retains its setting throughout the race. Expect a version for the Xray T3 soon.
