Customer Q&A - Atro MA10000A


Atro

ATRO Engineered Systems (ATRO) is a supplier of heavy-duty proprietary polyurethane suspension parts designed to deliver longer-lasting performance and reliability. ATRO’s free-rotation bushings with proprietary polyurethane material deliver longer life, lower cost-per-mile bushings that are superior to standard rubber or other polyurethane bushings. ATRO bushings are manufactured in the U.S.A and have proven to last three to five times longer than standard rubber and polyurethane bushings.

ATRO’s free-rotation design allows the inner piece to rotate freely, eliminating bushing “wind-up” and allowing less stress on the bushing material and ultimately the suspension components, thereby helping to prevent premature failure.

ATRO Bushings:

  • Meets or exceeds OE specifications
  • Eliminates bushing “wind-up”
  • Installs easily and requires no maintenance or grease
  • Resists contaminants such as road salt, grease, oil, acidic cleaning solvents, hydraulic fluid, diesel fuel, and more
  • Provides a longer life – up to three to five times longer than traditional rubber bushings
  • Enables the suspension to operate as designed to minimize premature part failure

ATRO Engineers Systems’ patented designs, state-of-the-art manufacturing plant and extensive aftermarket distribution network make them an industry leader developing products which improve performance, eliminate downtime, and help control costs.
