Heavy brass outer portal housing for TRX4 rigs

This 18-piece brass outer portal housing set is made for TRX4-style portal hubs and is intended to change wheel-end mass for better grip on uneven trails. The housings are a drop-in style for compatible portal assemblies and fasten using the included stainless steel cap head screws.

Material and role: brass adds unsprung weight at the wheel end when compared to stock alloy or plastic housings, a modification often used to increase slow-speed traction and aid recovery from digs in trail conditions. Any wheel weight figures provided with the product should be confirmed on your scales as part of setup checks.

Fit and installation: outer diameter is 43mm, and the housings require a wheel inner bore greater than 43.5mm to fit without interference. Verify wheel bore and hub stack clearance before fitting, and ensure screw lengths and thread engagement are suitable for your axle configuration.

Packing includes

  • BRASS OUTER PORTAL DRIVE HOUSING - 2pcs
  • Stainless Steel Cap Head Screw 2.5*10 - 12pcs
  • Stainless Steel Cap Head Screw 2.5*8 - 4pcs

Check that your wheel inner bore exceeds 43.5mm and trial-fit one side using the supplied screws to assess steering and suspension changes before completing both sides of the vehicle.

Will these housings clear common TRX4 wheels?

Clearance depends on wheel inner bore; these housings need a wheel inner opening larger than 43.5mm to avoid contact.

What screws are included with the kit?

The kit supplies stainless steel cap head screws: 2.5x10mm (12pcs) and 2.5x8mm (4pcs), plus the two brass housings.

Should I expect changes to suspension tuning?

Yes, increased wheel-end weight alters unsprung mass and can affect damping and steering; rechecking shocks and spring rates after fitting is recommended.

Do these housings require extra parts to install?

No extra parts are normally needed beyond what is supplied, but confirm screw lengths and hub stack depth on your specific axle to ensure a secure fit.
