Product Description
Looking for a Toyota LandCruiser HDJ100 Turbo Diesel/ FZJ105 6 cylinder petrol modified gearbox? Gympie 4WD Spares supplies professionally reconditioned exchange gearboxes featuring revised 2nd and 5th gear ratios for improved drivability, smoother highway cruising and approximately 400 RPM lower engine speed in 5th gear. Designed for owners who tow, tour and travel long distances, this modified gearbox is built to provide a more relaxed driving experience while maintaining Toyota reliability.
Professionally Reconditioned with 5th Gear Upgrade
Our Toyota LandCruiser HDJ100 (Turbo Diesel)/FZJ105 (6 cylinder petrol) modified gearbox combines a professionally reconditioned gearbox assembly with revised factory-style 2nd and 5th gear ratios. The revised 2nd gear helps improve spacing between 1st, 2nd and 3rd gears, making the vehicle more comfortable to drive when towing, climbing hills or driving through changing terrain. The upgraded 5th gear helps reduce engine speed by approximately 400 RPM during highway cruising, creating a quieter cabin, a more relaxed driving experience and helping reduce fuel consumption on extended trips.
Why Choose the 5th Gear Upgrade?
- Approximately 400 RPM lower engine speed during highway cruising
- Improved drivability through revised 2nd gear spacing
- Quieter, more relaxed cruising on long-distance trips
- Helps reduce fuel consumption during highway driving
- Ideal for towing caravans, boats and trailers
