Configure your Transfer Box your way, following the options below:
Vehicle Type
All Defenders have Rover axles fitted. Salisbury axles are a military heavy-duty option.
Model
If your vehicle has an engine swap, select the option that corresponds to the original factory engine.
Form
Standard is a factory original replacement with a sleeved casing as standard.
Winchester Gears Stage LT230's are upgraded versions of the standard Defender and Discovery Transfer Boxes. We carefully examined common points of failure and implemented effective solutions, building upon existing improvements with our own enhancements.
Sleeved Main Casing The intermediate shaft bore, prone to wear and oil leaks, is machined and fitted with a steel sleeve. Additionally, we address the main-shaft bearing bore, which is often damaged, by fitting a top-hat sleeve.
Intermediate Shaft The intermediate shafts holding the gear in place frequently wear out, causing transmission noise and, in late 1.21 gear-sets, total gear failure. Our Heavy Duty Shafts are crafted from 17.4ph material to ensure durability.
High Capacity Sump Available as an additional extra, this sump increases oil capacity by 0.6 litres, aiding in keeping the transfer box cool and well-lubricated.
Centre Differential
Stage 1: Features a heavy-duty one-piece cross shaft, replacing the weaker two-piece design, a common failure point.
Stage 2: Incorporates an Ashcroft ATB Limited Slip Diff, a helical design that optimally distributes torque and drive between the front and rear axles. This provides improved traction and eliminates the weakness of the standard unlocked center diff, ideal for racing on low-traction surfaces.
Ratio
Ratio options are available depending on the intended use and engine fitted. Use the ratio calculator to determine which is best suited. If you are unsure, tell us about your build via email and we will advise accordingly.
Front Output Flange
If running a Discovery 2 double cardan prop shaft choose the double cardan flange. For all other applications including Gwyn Lewis propshafts choose standard.
