1. This complete balance suspension equalizer assembly is a key tandem axle chassis fitting for heavy commercial vehicles and transport semi-trailers. The main beam is forged alloy steel with rigorous heat treatment to achieve ultra-high structural strength and impact resistance, solving the failure problems of bending and fracture of ordinary cast suspension under heavy load.

2. All matched balance pins and bushes are precision machined with self-lubricating design, which minimizes friction and wear during long-distance transportation, cuts down maintenance costs for fleet owners. This suspension equalizer can balance load distribution between dual axles efficiently, stabilize vehicle body, reduce tire abnormal abrasion and protect axles and leaf springs from overload damage.

3. We supply multiple specifications compatible with mainstream brands including BPW, SAF, FUWA, Howo, Shacman, Man and Volvo, covering 13T,16T,20T,24T,32T load series. Each product passes strict dimensional inspection and hardness test before delivery, with anti-corrosion surface treatment to adapt to all harsh transport environments. Available as OEM direct replacement spare parts, custom size and OEM marking service are supported, factory wholesale with reliable quality and fast lead time.
