ATRO Engineered Systems Inc has expanded its product line for Mack trucks.

The ATRO line of suspension parts now includes two different spring eye and leaf spring bushings, three different torque rod and trunnion bushings, and six pads including the firm's newest offset lower pad. Also offered are three insulators; three motor mounts; and a cab mount, hood pin, and shock bushing.

A patented, freely rotating pin design in the torque rod bushings delivers a more trouble-free suspension because it allows only centerline loading of the suspension while maintaining proper ride height.

Urethane materials used in ATRO products are less susceptible to chemical attack than rubber.
