This RC-scale pendulum wheel weight set is made for TRX4 MERCEDES-BENZ platforms and fits to the outer case of the front and rear knuckle arms, installing onto a 23mm hex. A central bearing with a Delrin collar and a tapered pendulum profile keeps the added mass low and biased downward so the axle assembly helps the model retain grip on rough, uneven ground while crawling.
The upgrade increases the wheel hex to 23mm and raises each wheel's downward mass to boost low-speed stability and climbing angle when the chassis meets depressions or steep obstacles. The assembly is intended for RC wheels with a 58mm inner diameter and a wheel thread hole sized for 5mm fasteners. Weight of a single pendulum plus hex is specified as 225 grams by the source material supplied with the product.
Fit these pendulum weights when you want extra low-mounted mass to improve crawling traction and angle support on TRX-4 MERCEDES-BENZ models; always verify wheel inner diameter and thread hole size before installation.
