Thread: Undersize spare & locking hubs

Amazing! I never even considered this as an option on a P38, let alone thinking someone actually making such a device. I have NFI how a P38 would handle as a 2WD/RWD vehicle but it would make power slides a lot more fun

I'm tempted to buy a set just to see what they do. Surely something has to screw up somewhere? On pre-99 2W-TC vehicles maybe ok, on post-99 4W-TC there's gotta be some confusion, although TC is based on ABS not wheel drive I guess.

If you are not fussed about the other options (carrier, spare in boot etc) I would strongly recommend sticking with stock 29" tyres. Nothing wrong with them at all... your speedo stays within spec and you can get almost anywhere with the right tyres... prefer 16" over 18" rims for wider selection of tyres.

Sure, I run 33"s but mine has a heap of mods to cater for it, including lift kit and spare tyre carrier. Even without the lift, my P38 would sit 2" taller than stock but the scrubbing would make it unusable. The lift kit avoids scrubbing on all but the lowest EAS setting and adds another 2" of lift. NB: makes it harder to fit in my garage and underground car parks.

Don't worry so much about look, and focus more on capability. Just get a good set of 29" MT or ATR tyres and your P38 will leave those Toyo/Jeep/Patrols in it's dust, if doesn't already... I've had my P38 leave other/lesser 4WD's wanting even when running my other 18" rims and road tyres.

Cheers, Paul.

Why on earth would you fit free wheeling hubs to a constant 4wd vehicle (of any sort)?

Completely pointless waste of time and money.

Does the P38 have a lockable transfedr case such as the Disco1 or a viscous one like some RRC?

If it doesn't lock then FWH wouldn't do any good.
Also do the rims you use allow for a FWH in the centre of it?

Viscous coupling.

I'm doubtful that those are for a P38A. If they were, they'd cover 1995 onward. Note also they say for 10 spline and 23 spline axles.

Also, those part nos, in the MileMarker catalogue refer to:

　
BRITISH LEYLAND
Land Rover (6 bolt 10-spline axle)

420

Land Rover (6 bolt 24-spline axle)

432

Series I, II, III, All W.B.

432

Probably not so simple on P38 (if even available), but I have a conversion like the one described in mind for mrs 100 series cruiser. SA business sells one. Benefits are: Improved fuel economy (15%) and substantially reduced wear and tear on (front end) drive train components... oh yeah, and as Paul alluded... hanging the rear out on demand and roostering others when playing in mud!

Reduced wear on front axle components, increased wear in transfer case .

Reduced fuel consumption (15%), decreased road holding / stability (30%?) .

Hanging the back end out while playing in the mud - Priceless .
