Part Time 4WD Conversion Kit – Toyota LandCruiser 80 Series

Part-Time 4WD Conversion Kit to suit Toyota LandCruiser 80 Series

Marks 4WD manufactures a heavy-duty part-time 4WD conversion kit that converts the factory-fitted 80 series LandCruisers with constant (full-time) 4WD to Part Time 2WD.

(All RV, GXL, and Sahara LandCruisers manufactured from 01/1990 are fitted with the full-time HF2A transfer case.)

The Marks 4WD kit features heavy-duty, free-wheeling hubs fitted with a heat-treated carbon steel drive ring, engineered to strengthen the weak point on the factory hub.

Vehicles fitted with front diff locks and the standard AVM free-wheeling hubs have been prone to breaking the factory hub, making our kit the ideal upgrade to your 4WD

ABS Live Axle Models

When ABS-equipped live axle vehicles are fitted with a Part-Time 4WD kit, the ABS sensor reading from the CV joint becomes inoperable, resulting in the ABS warning light displayed on the dashboard.

Our ABS relocation kit moves the sensor from the CV joint to the wheel hub, ensuring it operates according to factory specifications.

Viscous Centre Diffs

Vehicles equipped with viscous-coupled centre differentials can still utilise our Part-Time 4WD kit. To complete the installation, you will need to purchase the ‘Centre Diff Lock’ button, as used on the GXL models. The switch is an easy plug-and-play with the necessary plug & wiring already provided in the Toyota wiring loom.

History

Marks4’s WD prototype conversion was first installed on our 6.5 Chevy diesel 80 Series in September 1999.

The conversion gave the vehicle a new lease of life with improved handling, better acceleration, and lighter steering. The steering no longer tends to pull hard when powering out of a corner; this should result in less wear and tear on the steering components, such as the tie rod ends and steering box.

The steering has also become more direct or positive. The acceleration improved due to reduced losses associated with driving the front differential, driveshaft, and CV joints. With these components no longer being driven, a considerable increase in their service life can also be expected.
