Engineered brass pendulum weights for TRX4

This brass pendulum wheel weight set is engineered for TRAXXAS TRX4 trail crawlers to concentrate mass at the wheel end and reduce the effective centre of gravity, improving slow-speed traction and tyre contact. The pendulum geometry is narrower at the top and wider at the base and operates on a bearing with a Delrin collar that maintains downward orientation through wide wheel articulation. The design supports traction recovery when negotiating uneven ground and enables larger crawl angles without losing ground contact.

Installation targets the outer drive portal; wheels must have a 45mm inner diameter and a 5mm threaded hole to accept the assembly. The supplied 23mm hex adapter increases offset versus the stock hex to position the pendulum correctly. Each pendulum plus hex assembly is 133 grams and the set is supplied as an aftermarket wheel hub upgrade for crawlers.

What are the exact wheel fit requirements for TRX4023XX?

The assembly requires a wheel inner diameter of 45mm and a 5mm threaded hole to ensure proper seating of the pendulum and 23mm hex adapter.

How does the Delrin collar maintain pendulum orientation?

The Delrin collar guides the pendulum on its bearing, minimising lateral play and allowing the mass to hang downward through steering and suspension movement for consistent ground engagement.

What is the mass and adapter offset of the unit?

Each pendulum plus 23mm hex adapter assembly weighs 133 grams; the 23mm hex provides an 18mm wider offset compared with the original hex dimension noted in the specifications.

Any special installation considerations?

Ensure the outer drive portal and wheel clearances can accept the larger hex offset and verify wheel bore and thread dimensions match the listed requirements before installation.
