Brass portal knuckles for precise crawling

This 14 piece brass front knuckle arm kit is a scale upgrade intended for AXIAL Capra 1.9 Unlimited platforms. It combines brass outer portal housings with inner knuckle parts and stainless fasteners to increase unsprung mass at each wheel, influencing tyre load and contact during slow technical crawling. The text focuses on fitment notes, installation considerations, and tuning roles rather than marketing claims.

The brass components add about 115g per wheel, helping tyres maintain contact over uneven rock sections and potentially improving steering authority when used with wheels that have an inner diameter sufficient to accept the 43mm outer parts. Always confirm wheel bore and hub interface compatibility prior to fitting this accessory.

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

Use this set to increase wheel-end mass for improved low-speed traction and tyre conformity on jagged lines. Verify bore clearance and fastener lengths, then recheck torque after a short run-in period.

This item is compatible with

  • AXIAL-1/10 CAPRA 1.9 UNLIMITED-AXI03004

Do these require special wheels?

They need wheels with an inner bore greater than 43mm to clear the brass housings; check your wheel spec before buying.

Will bearings take more strain?

Increasing unsprung weight increases load on bearings over time; inspect bearings regularly and consider heavier duty bearings if you run the set long term.

Can I use these for scale rigs only?

While they enhance scale weight and crawling traction, they are suitable for any Capra 1.9 Unlimited setup that meets the wheel bore and hub interface requirements.

Is installation reversible?

Yes, these replace the stock knuckles using the supplied fasteners; keep the originals to revert to stock if needed.

Should I alter shock settings?

You may need to soften spring rates or tweak damping to compensate for the increased wheel-end mass to maintain articulation and ride height.
