Introducing Winchester Gears Bespoke Engineering
For those one-off projects where standard options simply won’t do, Winchester Gears offers a limited number of bespoke drivetrain builds each year. If you’re working on a specialist restoration, a high-performance conversion, or a unique engineering challenge—and can’t find what you need in our configurator—our team can design, fabricate, and assemble a custom solution tailored specifically to your requirements.
With decades of drivetrain expertise and precision workshop capabilities, we specialise in creating components and assemblies that integrate seamlessly with your project while delivering exceptional strength, performance, and reliability. For bespoke enquiries, please contact us via email to discuss your concept, technical requirements, and available build slots.
Below are a few examples of recent bespoke projects completed in our workshop:
A complete transformation of classic Series axle assemblies, including:
ATB (Automatic Torque Biasing) differentials
CV joint conversion for smoother articulation and improved strength
Full disc brake upgrade
300M high-strength halfshafts and heavy-duty drive flanges
These upgrades deliver modern performance while retaining the iconic Series aesthetic.
For applications requiring maximum crawl capability or ultra-controlled low-speed drivability:
Built using genuine Maxidrive gear sets
Low-range ratio reduced by 30% or 40%, depending on specification
Ideal for off-road competition, rock-crawling builds, and high-torque engine conversions.
Designed for performance conversions using the robust manual Tremec T56 gearbox:
Spark-eroded, custom-profile input gears
Tailored specifically for manual LS3 installations
This allows a T56 to interface cleanly with an LT230 transfer box while maintaining strength and alignment under high horsepower.
A fully custom MT82 gearbox engineered for Coyote powertrains:
Uses the Mustang bellhousing mated to a Land Rover tailhousing
Provides a manual gearbox option for Coyote Defender builds
Retains proper drivetrain geometry and transfer box compatibility
A true hybrid solution for modern V8 conversions.
Upgraded 101 FC axle sets equipped with:
Full disc brake conversion
ATB centre differentials
Multiple ratio options to suit power and tyre size
Bringing 101 drivability and safety up to modern standards.
A heavy-duty solution blending classic Land Rover architecture with Dana 60 capability:
Custom-machined Salisbury axle casings
Wide range of Dana 60 gear ratios available
Ideal for high-torque engines, oversized tyres, and extreme-use vehicles
