Modifying 2nd and 5th gears in a Land Cruiser 79 can offer several advantages, primarily related to improving performance and driveability. Here are some potential benefits you can expect from these modifications:
 
Gear Ratio Adjustment: 
Modifying the gear ratios in 2nd and 5th gears allows you to tailor the vehicle’s performance to your specific needs. By changing the gear ratios, you can optimize acceleration, top speed, and fuel efficiency based on your driving preferences and the vehicle’s intended use. This can be especially beneficial when towing heavy loads, off-roading, or driving in specific terrain conditions.
 
Improved Low-End Torque:
Adjusting the gear ratio in 2nd gear, typically referred to as “shortening” the gear ratio, can enhance low-end torque. This modification is particularly useful for off-roading or situations where you require quick acceleration at lower speeds, such as climbing steep inclines or maneuvering through difficult terrain.
 
 
Enhanced Highway Cruising:
Modifying the gear ratio in 5th gear, often referred to as “lengthening” the gear ratio, can result in improved highway cruising ability. This adjustment can lower engine RPM while maintaining speed, which can lead to reduced fuel consumption and engine wear during extended periods of highway driving. Additionally, a longer 5th gear ratio can improve overall comfort by reducing engine noise and vibration at high speeds.
 
Personalized Driving Experience: 
Modifying specific gear ratios can offer a more customized driving experience, allowing you to fine-tune your Land Cruiser 79 to match your preferences and driving style. Whether you prefer a more responsive and agile driving experience or prioritize fuel efficiency and relaxed cruising, gear ratio modifications can help achieve the desired outcome.
