Trailer Chassis Parts for Sale

The Latest Update Of Order Delivery On 25 Mar 2020

Ultraton Semi Trailer Chassis Parts are lightweight and rigid, and the leaf springs will not shift laterally during use. The wear resistance block of the balance arm has a grease lubricating nozzle, which reduces the sliding friction between the steel plate and the wear resistance block of the balance arm.

Our Trailer Chassis Parts' torque rod angle is reasonably designed, which effectively reduces tire friction and prolongs the service life of the tire during frequent bumps in the entire vehicle.
