STEERTEK - Fabricated Front Steer Axle


	Literature Weight Savings Calculator

Designed as the platform for OEM proprietary and next generation front axle / suspension systems, Hendrickson's STEERTEK axle is the first fabricated front steer axle in the industry. Based on proprietary design and manufacturing technology that give the system a superior strength to weight ratio, STEERTEK serves as the durable, lightweight alternative to antiquated I-beam axles. The patented two-piece knuckle contributes to outstanding turning radius and reduced maintenance. Chosen by many OEMs as the standard axle for select vehicle models, STEERTEK is approved for on-highway and medium-duty trucks, buses and motorhome applications and is available in capacities up to 14,600 lbs.

Increased Maneuverability

Optimized steering performance delivers up to 55-degrees of wheel cut, for better maneuverability

Adaptable Design

Right-hand drive configurations are available for global applications

Weight Savings

STEERTEK’s unique design provides up to 30 pounds of weight savings compared to traditional forged I-beam axles

Advanced Suspension Integration

The STEERTEK axle easily integrates with a variety of suspensions, allowing STEERTEK to serve as the platform for many OEM proprietary and next generation front suspension systems

Reduced Maintenance

The unique two-piece knuckle design eliminates the need to remove the kingpin to service the bushings, helping to reduce maintenance time and life-cycle costs

Rigid Axle Beam

The box-shaped cross section resists horizontal, vertical and twisting forces more effectively than traditional I-beam axles while helping to reduce dynamic camber and toe

Contributes to improved steer-tire life
