The ATRO EQ53-35158 is a heavy-duty fabricated equalizer beam designed for Hutchens H9700 and H9600 series four-spring trailer suspensions.This kit is a performance upgrade over standard rubber-bushed beams, featuring ATRO’s signature polyurethane bushing for increased service life, improved axle alignment, and better resistance to chemical and environmental wear.
Polyurethane Technology: Includes the EQ53-35601 bushing, which is chemically resistant to grease, oil, road salt, and cleaning solvents.
Improved Ride Quality: Reduces vibrations and suspension "walk," leading to more even tire wear and less stress on other suspension components.
Zero Maintenance: Unlike rubber, ATRO polyurethane does not require lubrication and will not rot or crack over time.
Full Hardware Kit: This part number includes the necessary mounting hardware for a complete, hassle-free installation.
