I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions

Q: Will this kit make the ride harsher when the truck is empty? A: No, the system is engineered to retain the factory ride quality when unloaded, and you simply add air when carrying or towing a load.

Q: Is drilling into the frame required? A: Most installations are entirely bolt-on using existing frame holes; only minor trimming of a bracket may be needed depending on bed configuration.
