TF450 TF E-Locker Electronic Diff Lock – 24 Spline – for Land Rover Defender, Discovery & Range Rover Classic

Upgrade your Land Rover’s off-road capability with the Terrafirma TF450 E-Locker Electronic Differential Lock – a heavy-duty selectable locking differential designed to deliver maximum traction exactly when you need it most.

Unlike automatic lockers or complicated air-operated systems, the TF450 E-Locker gives you complete control at the flick of a switch. Enjoy smooth, predictable on-road driving with the differential unlocked, then instantly engage 100% locking action for serious off-road terrain, mud, rocks, ruts, snow and technical climbs.

Designed specifically for 24 spline Rover-type axles, the TF450 is a popular upgrade for Land Rover Defender, Discovery 1, Discovery 2 and Range Rover Classic models used in expedition, overland, utility, military and recreational off-road applications.

WHY CHOOSE AN E-LOCKER?

The Terrafirma TF450 E-Locker offers the benefits of a fully locked differential without the complexity of air lockers. With no compressors, solenoids or external airlines to install, the system remains incredibly simple, reliable and easy to fit.

When activated, drive is transferred equally to both wheels, dramatically improving traction in low-grip conditions. This allows slower, more controlled off-road driving with less wheelspin and reduced stress on your Land Rover’s drivetrain.

IMPORTANT:
TF450 is designed for 24 spline Rover-type differentials only. Please confirm axle type, spline count and front/rear application before ordering. Earlier vehicles may require conversion to 24 spline halfshafts.
