Categories: , ,



  • Reduced spring interleaf friction increasing durability
  • Reduced dynamic hysteresis effects increasing reliability
  • Advanced materials developed by Hendrickson maintain spring rate without degrading vehicle performance improving reliability
  • Decreased overall assembly weight and contribute to light weighting


  • Steel grades are selected based on application and stress levels
  • Proprietary rapid heat furnaces designed to minimize decarb and maintain fine grain
  • Optimized peening process to further improve fatigue life
  • Patented multi-tempering process allows springs to run at maximum hardness, without the risk of hydrogen assisted cracking (HAC)
  • World class zinc rich primer with a zinc phosphate pretreatment
