Technical Highlights

  • Durability: 6061 T6 aluminium provides a predictable stiffness increase to reduce flex under load while preserving serviceability.
  • Smooth Operation: POM collars are integrated in the knuckle arms to lower friction at the pivot points and maintain consistent axle rotation.
  • Adjustable Design: The upper arms incorporate a tie rod style with counter-clockwise threads to permit precise length adjustments for alignment and handling tuning.

What alloy is used for the arms and why?

The arms use 6061 T6 aluminium for its strength to weight balance and consistent performance under repeated load cycles common in off-road use.

How do the POM collars affect maintenance?

POM collars reduce metal on metal contact, which lowers wear at the knuckle pivots and simplifies routine servicing. Keep collars free of abrasive debris for best results.

Will these arms require geometry changes after fitment?

The parts are designed to match OEM geometry; however, the tie rod style upper arms allow you to make small length changes to fine tune toe and camber for race or trail setups.
