GPM Racing Brass Outer Portal Drive Housing (Front or Rear)"heavy Edition"-10pcs Set for Axial SCX10 III Jeep Wrangler Rubicon (SCX3021AX)

Precision brass portal housings for Capra 1.9 platforms

This CNC-style brass outer portal drive housing is produced for AXIAL Capra 1.9 Unlimited chassis to increase unsprung mass at the wheel end and refine slow-speed traction characteristics. It is engineered for use on either front or rear outer portal positions where wheel bore and clearance match the component.

With an added mass of 64g per wheel, the housing increases normal force on obstacles and assists in recovery from tuck-in scenarios by improving low-speed grip and stability. The outer diameter is 43mm, so compatible wheels must have an inner diameter greater than 43mm to permit correct seating and secure mounting.

Supplied as a direct aftermarket replacement housing for hobby rock crawlers and trail rigs, the component is sold without internal gears or bearings and is secured using the provided stainless steel cap head screws. Verify portal geometry and interference before final installation.

Packing includes

• Brass outer portal drive housing – 2pcs
• Stainless steel cap head screw 2.5×10 – 8pcs

Use these precision brass housings when you require deliberate wheel-end weight for improved low-speed traction and recovery on Capra 1.9 Unlimited platforms; confirm wheel bore and portal clearance prior to fitment.

This item is compatible with

• AXIAL-SCX10 III JEEP WRANGLER-AXI03007

What bore clearance is required for correct fitment?

The housing outer diameter is 43mm; wheels must have an inner bore exceeding 43mm to allow proper seating and to avoid preload on bearings or interference with the portal face.

Do these housings include internal drive components?

No internal gears or bearings are included. These housings are outer shells only and must be assembled with your existing portal internals and the supplied 2.5×10 cap head screws.

How does added unsprung mass affect chassis tuning?

Adding 64g per wheel increases unsprung mass, which typically improves traction at low speeds but can alter shock damping and suspension response; review spring and damper setup after installation.

Are these housings corrosion resistant?

Brass offers good resistance to corrosion in hobby use. For trail use in corrosive environments, rinse and dry assemblies after exposure and periodically inspect fasteners for wear. Write Product Review Please sign in your account before you can write any review. Sign In Close
