Solid-steel safety arms lock automatically and continuously during ascent, transferring load off the hydraulic system when the lift is secured. Multiple lock positions allow technicians to choose the working height that fits the job, from brake service to underbody access. Air lock releases replace traditional spring releases and disengage the locks during descent with the push of a button. Zerk grease fittings help protect critical wear areas, while rugged rubber lift blocks support secure vehicle contact points during daily shop use.
