The SWAT lower arm is a direct replacement for HR4750. This lower provides a strong connection to the pivot gear and a secure mounting point for the hydraulic cylinder that extends the upper arm. Our rack and pinion lower arm for roll-off trucks is made from sturdy steel tubing and finished with a durable black powder coat. This allows for longevity and reliability to keep your trucks moving all day long.

SWAT was designed to be more dependable and robust than other roll off truck systems. We also made our parts to accommodate direct replacement for other common rack-n-pinion systems to eliminate the need to change out your entire system. This gives you the ability to upgrade common weaknesses of your current system without the expense and downtime of a complete system swap.
