LOUISVILLE, Ky. – Independent studies indicate that many operators are not ensuring slider locking pins are engaged before driving on-highway, according to ArvinMeritor and the company has introduced a new product to address the issue.

ArvinMeritor introduced its new Meritor RideSentry MPA series of trailer air suspensions,which have an angled pin design, at the Mid-America Trucking Show.

The company said the new RideSentry trailer air suspension was engineered to provide a very low cost of ownership.

Key customer-focused features include:

* Structural durability – high strength steel, contoured lateral plates, beaded center hanger brackets, and new profile side rails provide outstanding buckling, racking and curbing resistance.

* Patent-pending angled locking pins – available in the fall of 2006 to help prevent slider damage if operator releases handle but fails to engage pins.

* Bushing design – bonded rubber upper control arm bushings with steel thrust washers and extended warranty coverage to seven years parts / five years labour.
