  • Enhanced handling & safety under load
  • Raises rear ride height by approx. 40mm
  • No need to remove factory spring – simple bolt-on installation
  • Reduces sag and prevents premature suspension wear
  • Comes with extended U-bolts to fit the thicker dual-leaf assembly
  • Ideal for Mercedes Sprinter and VW Crafter (with 70mm wide single leaf)


Compatibility:

  • Volkswagen Crafter (Various years – confirm 70mm leaf width)
