Heavy brass front knuckles for improved traction

This 14-piece brass front knuckle arm set is an aftermarket upgrade tailored to AXIAL Capra 1.9 Unlimited vehicles. Brass outer portal housings combined with inner knuckle parts and stainless fasteners add measurable unsprung mass at the wheel ends, affecting balance and tyre contact during technical crawling. The following section covers fitment advice, installation notes, and tuning considerations rather than promotional language.

The set increases wheel-end mass by about 115g per wheel via the brass housings, which promotes tyre contact across rough sections and can widen effective steering and crawling angles when run with wheels that accept the 43mm outer diameter. Always confirm wheel bore and hub compatibility before installing these parts.

Packing includes

  • Brass Outer Portal Drive Housing - 2pcs
  • Inner Part Front Knuckle - 2pcs
  • Stainless Steel Round Head Screw 3x16 - 1pcs
  • Stainless Steel Round Head Screw 3x25 - 1pcs
  • Stainless Steel Button Head Screws 2.5x6 - 8pcs

Original Name / Part No:

Will these work with my existing Capra wheel set?

They will if your wheels have an inner diameter greater than 43mm to clear the brass outer housings; measure your wheels before purchase.

Does the added mass affect driveline wear?

Heavier wheel ends place more load on driveline components and bearings; inspect related parts more frequently if you use the set regularly.

Are the screws corrosion resistant?

The included screws are stainless steel and resist corrosion, but check fit and replace any that are incorrect length for your hub stack.

Can I tune shocks after fitting?

Yes, shock spring rates and damping may need adjustment to compensate for increased wheel-end weight to preserve articulation and ride height.

Is installation difficult for a home builder?

Installation is straightforward with basic hex drivers and patience; keep original parts if you want to revert to stock later.
