Conical gears for the Defender range from the standard 3.54 ratio to a 4.75 ratio, which is approximately 40% reduced and therefore suitable for extreme off-road use. The Defender conical gears are a crucial component of the vehicle’s drivetrain. Located downstream of the transfer case, they determine both high and low ratios. Thus, careful consideration is required when deciding to install reduced gears. While this provides a wider range of ratios for off-road excursions, it also significantly reduces the vehicle’s top speed, which can be problematic for fast travel.Installing conical gears is a complex process that requires a specialized mechanic. When correctly installed, a high-quality conical gear should never break. Reinforced models with a ratio similar to the standard one are also available, as well as models for the rear axle of the Defender 110 with the Wolf axle.
