Engineered brass front knuckles for crawl performance

This 14pcs brass front knuckle arm kit is a precision upgrade aimed at AXIAL Capra 1.9 Unlimited chassis. CNC-style brass outer portal housings combined with matching inner knuckle components and stainless steel fasteners add quantified unsprung mass at each wheel end, altering contact forces and slow-speed behaviour. The content below addresses fitment, installation checkpoints, and setup implications rather than promotional claims.

The housings increase wheel-end mass by about 115g per wheel, aiding tyre contact on uneven rockwork and potentially expanding effective steering and crawl angles when paired with wheels whose inner bore clears the 43mm outer diameter. Verify wheel bore, hub interface, and fastener length before assembly to ensure correct engagement and avoid interference.

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

Specifications

  • Item: AXIAL Racing CAPRA 1.9 UNLIMITED Brass Front Knuckle Arms heavy Edition -14pcs set
  • Material: Brass outer housings with stainless steel fasteners
  • Model Number: SCX3021X
  • Compatibility: compatible with AXIAL Capra 1.9 Unlimited
  • Outer diameter: 43mm (requires wheel inner diameter > 43mm)
  • Wheel weight increase: ~115g per wheel from brass components

Fit this bolt-on upgrade when measured increases in wheel-end mass are needed to improve traction and tyre conformity at low crawl speeds. Confirm clearance and fastener engagement, check torque after an initial run, and inspect bearings and hubs as part of routine maintenance.

This item is compatible with

  • AXIAL-1/10 CAPRA 1.9 UNLIMITED-AXI03004

What clearance is required for wheel fitment?

Wheels must have an inner bore greater than 43mm to clear the brass outer portal housings. Measure the wheel bore and verify there is no contact with the new housings before final assembly.

How should I check fastener engagement?

Install supplied stainless screws to the specified engagement depth, then perform a torque check after a short break-in run to ensure there is no loosening or interference with hub components.

Will these parts change suspension tuning?

Yes, the added wheel mass changes unsprung dynamics; assess spring rate and damping to maintain articulation and ride height for your intended crawling style.

Are these reversible to stock configuration?

The kit is a bolt-on replacement; retain original knuckles and hardware to revert to stock if required.

What maintenance is recommended after fitting?

Inspect bearings and hub interfaces periodically for increased wear, verify fastener torque after initial runs, and check wheel balance if you notice vibration at higher speeds.
