Product Highlights

ATRO polyurethane load pads for heavy-duty trucks. Engineered to absorb shock, reduce bounce, extend component life, and support whole system integrity.

Why choose ATRO Load Pads?

ATRO utilizes proprietary polyurethane formulations that are 3–5× stronger than rubber, resisting oil, grease, road salt, hydraulic fluid, and cleaning solvents.
Unlike traditional rubber “elephant’s feet” pads, ATRO’s low-rebound material eliminates bounce and helps absorb shock—resulting in smoother ride quality, less stress on surrounding components, and reduced cab damage.

Compatible with complete system upgrades.

ATRO load pads are designed to integrate seamlessly with our suspension kits and components. When installed as part of a whole-system approach, you maximize alignment accuracy, minimize mismatched wear, and simplify future maintenance.
