We had a visit from Luke at LOF Clutches this week to take a closer look at their Land Rover Series CV conversion.

Luke wanted to personally bring the kit over to Wi******er Gears and, rather than simply dropping it off, assemble it with us from start to finish. The idea was to demonstrate exactly how the kit goes together, check the installation process and, most importantly, prove the concept on the bench.

The conversion has been very well thought out and makes clever use of readily available Land Rover Defender components, including:

Defender stub axle
Defender wheel bearings
Defender hub
Defender drive fl**ge
Custom-manufactured half shafts
CV joints designed to provide constant velocity drive at the front axle

The whole assembly went together extremely well, and it’s clear that a lot of thought has gone into the design and the way the individual components work together.

But why would you want a CV conversion on a Series Land Rover?

A standard Series front axle uses universal joints (UJs) rather than CV joints. This isn’t normally a major issue because the Series transfer box is selectable between 2WD and 4WD, meaning that in normal road use the front axle isn’t continuously driving.

However, things change if you’re looking to run permanent four-wheel drive.

An LT230 transfer box gives you permanent 4WD (2WD selectable version are available) but putting that into a standard Series front axle means the front UJs are now continuously transmitting drive. CV joints are much better suited to this application because they maintain a constant velocity through the steering angle, while also providing a smoother method of transmitting drive when the wheels are turned.

This is particularly relevant when you’re combining a Series chassis and axles with a more modern drivetrain.

And that’s where this conversion gets really interesting for us.

The LOF CV conversion pairs extremely well with our Series R380 + LT230 conversion.

You essentially end up with a Series Land Rover retaining its original character and appearance, but with a much more modern drivetrain underneath:

Series axle → LOF CV conversion → LT230 permanent 4WD → R380 gearbox

It gives you the benefits of permanent 4WD without asking the original Series front axle UJs to do something they were never really designed for.

We really like what Luke and the team at LOF have done with this kit, and it was great to get hands-on with it, go through the installation together and see the finished assembly for ourselves.

We’re big fans of the wild builds! Chevy small block engine swaps, BMW M57 engine conversions, Mercedes OM606 engine powerhouses and everything in between that pushes a Defender to its limits.

But there’s something that hits differently.

A true, numbers matching Land Rover Defender, rebuilt the way it left the factory. Properly maintained, carefully restored, and kept faithful to its roots.

That’s the magic of Land Rovers — they’re basically mechanical Meccano sets. You can strip them down, rebuild them, and tailor them to any purpose, any look, any personality.

Yet somehow… the originals still stand apart.

There’s a character, a story, and a purity you just can’t replicate.

This freshly dressed TD5 gearbox and transfer box is heading home, ready to be reunited with one of those special vehicles a rare Land Rover Defender G4 Limited Edition.

Building or already driving an M57-powered Defender? Then you’re officially in the “how fast do I want to go vs. how noisy do I want it to be?” club. The LT230 transfer box ratio you choose makes a huge difference to how the truck feels. You’ve basically got three flavours to pick from: 1.2, 1.1, and 1.003.

If you’re regularly towing plant, trailers, or other questionable “that’ll be fine” loads — and you live on twisty B-roads — the 1.2 ratio is your friend. It keeps the revs up and the torque right where you need it for pulling, but expect the engine to get shouty once you’re pushing past 50 mph.

At the other end of the spectrum, 1.003 is the tallest ratio you can get. This is the one for motorway warriors and commuters who don’t want their Defender screaming at them for three hours. The M57 has more than enough grunt to pull it, and it makes cruising genuinely pleasant.

Can’t decide? Want a Defender that can tow, cruise, and still make you giggle on a B-road? Then 1.1 is the Goldilocks spec — the all-rounder that suits most builds and driving styles.

Bottom line: think about how you actually use your truck, not how you wish you used it. The right ratio turns an M57 conversion from “cool project” into “daily grin machine.”
