TRE 4x4 Bolt-on Portal Axle — Nissan Patrol Y60 (Gear/Chain Options, ~4.5" Hub Lift)

Give your Patrol Y60 true portal clearance with the TRE 4x4 Bolt-on Portal Axle system. Compact portal boxes relocate the hub centreline to add around a 4.5-inch lift at the wheels while keeping factory suspension pick-up points. Choose gear-driven or chain-driven portals with multiple reduction ratios to match large tyres and off-road gearing.

Key benefits

• ~4.5” hub lift — raises the diff pumpkins for serious ground clearance and better break-over angle.
• Two portal architectures — gear-driven (ratios 1:1.2 / 1:1.33) or chain-driven (ratios 1:1.16 / 1:1.25 / 1:1.27 / 1:1.36).
• Integrated aluminium housings — high-strength, lightweight portal boxes built for harsh terrain.
• Complete conversion package — includes matched brake components and reinforcement brackets.
• Y60-friendly geometry — preserves OEM suspension pick-up points for a tidy install.
• Wheel & tyre guidance — typically 17” wheels (around ET +50) with 35–40” tyres (check clearance/local rules).

What’s included (per axle kit)

• Portal hub assemblies — LH & RH (gear- or chain-driven, chosen ratio)
• Brake package — discs, calipers and brake hoses matched to the portals
• Reinforcement brackets and application-specific mounting hardware
• Axle-side components as required by configuration

Contents may vary with gear vs chain option and front/rear axle. We’ll confirm the exact contents before dispatch.

Technical specs

Installation & UK notes

• Professional installation required — braking and steering geometry are affected; full alignment is essential.
• Gearing — portal reduction and tyre size change, effective gearing; diff re-gear may be recommended.
• Road legality — ride height/tyre protrusion rules vary; check MOT/IVA compliance before road use.
• Post-fit — bleed brakes, torque to spec, recheck fasteners after bedding-in and the first 500 miles.

FAQs

1) How much lift do portals add?
About 4.5 inches at the hub centreline, lifting the axle pumpkins for improved clearance.

2) Gear-driven vs chain-driven — what’s the difference?
Gear portals use meshed gears (ratios 1:1.2 / 1:1.33). Chain portals use heavy-duty chains (ratios 1:1.16 / 1:1.25 / 1:1.27 / 1:1.36). Choose based on tyre size, crawl needs and packaging.

3) What wheels and tyres should I run?
Typically 17” wheels with around ET +50 and 35–40” tyres, subject to checking braking/steering clearance and UK regulations.

4) Is it bolt-on for the Y60?
Yes — the system is designed to retain OEM suspension pick-up points with minimal chassis changes; professional fitting is required.

5) What’s included in the kit?
Portal hubs (pair), brake discs/calipers/hoses, reinforcement brackets and hardware. Axle-side components vary by configuration.

6) Do I need to re-gear?
Often recommended depending on tyre size and chosen portal ratio, to restore drivability and transmission load.

7) Is CTIS compatible?
Yes — portals can be integrated with Central Tyre Inflation Systems (advanced builds).

8) Is it UK road-legal?
Depends on lift, tyres and associated modifications. Check MOT/IVA rules; some builds are off-road-only.
