Why custom portal axles?
Not every 4×4 has an off-the-shelf portal axle kit. That’s where TRE4x4 steps in – a European manufacturer specialising in custom portal axle systems built for unique vehicles and competition projects. Through OFM4x4 UK, you can commission made-to-order portal solutions engineered precisely for your vehicle’s dimensions, suspension travel and tyre goals.
Core features & advantages
- Custom geometry: designed to match OEM axle width, diff type and steering layout.
- Selectable reduction ratio: common choices from 1 : 1.3 to 1 : 1.5 for perfect crawl control.
- Strength to match purpose: options from lightweight alloy hubs to heavy-duty steel casings.
- Braking flexibility: accepts Wilwood, Brembo or OEM calipers depending on the build.
- Adaptable bolt patterns: 5-, 6-, 8- lug, or bespoke flanges for race applications.
- Integration ready: CTIS, ABS, and portal vent systems available.
Each set is precision-machined and test-assembled before shipment, ensuring reliability and long-term service even in expedition or competition use.

FAQs
1. Can TRE4x4 build portals for any vehicle?
Almost – as long as accurate axle data or a sample housing is supplied, custom portals can be engineered for most solid-axle or independent setups.
2. What is the usual production time?
Most bespoke sets take 8–10 weeks after CAD confirmation. Complex racing assemblies may need longer for prototype testing.
3. How much lift will portals add?
A typical hub design adds ≈ 130 mm of differential clearance without altering suspension height, depending on tyre size and ratio.
4. Are custom portals road-legal in the UK?
Yes – when correctly installed and declared to insurers. OFM4x4 ensures compliance with braking performance and lighting height rules.
5. Can I mix portal axles with my existing lift kit?
Absolutely. Portals work perfectly with 50–75 mm lifts, retaining stability while gaining diff clearance and torque control.
6. Do TRE4x4 portals support CTIS or ABS?
Yes – both systems can be integrated at the design stage when requested.
