Designed as the platform for both Hendrickson's next generation and OEM proprietary front suspension systems, STEERTEK NXT provides greater reliability, innovation, weight savings, and a durable, lightweight alternative to old generation I-beam axles. STEERTEK NXT manages the increased brake torque loads required to meet recent changes to FMVSS-121 and will accommodate a variety of wheel end and knuckle designs, including global specifications. 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.

Weight Savings
- STEERTEK NXT's unique design provides up to 23 pounds of weight savings compared to traditional forged I-beam axles.
Advanced Suspension Integration
- The STEERTEK NXT 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
- Premium kingpin bushings and seals provide enhanced protection from the elements to improve bushing life.
Rigid Axle Beam
- Manages the increased brake torque needed to meet FMVSS-121 stopping distance regulations
- Integrated axle seats to improve ground clearance, reduce part count, and simplify assembly
Brake Compatibility
- Compatible with drum brakes or disc brakes
- Accepts both 5/8" and 3/4" brake hardware
