Ashcroft part time 4 wheel drive conversion

Does anybody have any experience with the
Ashcroft part time 4wd kits ? Do you think this will help with fuel economy?

There will be no affect on fuel economy.

Locking hubs are included in the kit so the front axle does turn. Less drag= better performance ?
Red why do you say that?

Very interesting. Moving less stuff = better economy I would think.

Yeah isn't that the point?

Once I prove my gearing is good on my eve project, I plan to get an Ashcroft rebuilt LT230 with the part-time 4xd kit for this very reason.

Hubs only work on early 83-93 NAS 110 front cvs.

Worth noting these things handle very differently as a 2wd versus a full time 4wd... if you dont believe me take out your front driveshaft and drive it with the center diff locked. I would not own a coil sprung rover converted to part time 4x4.

The change in power loss is not measurable. Spinning those components does not use very much energy. These trucks are bricks.

There are a lot of downsides. 2WD on gravel roads and on the road in snow is horrible. I have a friend that put one in thinking what you guys think. There was no measurable change in mileage. On long highway trips we have done together, I got 10% better mileage than him... He hates it on the gravel roads. He can't keep up with everyone as it is not safe to drive as fast as the other people in full time 4WD. The full time 4WD is one of the big pluses to these trucks.

The real advantage I saw was that it eliminated the one weak part of an LT230.

+1

Whenever i've blown a front diff or CV, and come home in "difflock & no front prop" the handling is really different. seems more wallowy (i suppose the front axle is causing some torque twist type thing that helps to keep the vehicle settled)

I don't really know what it is, I just know its wierd.

I can see all of those points if I did a lot of driving in those conditions. I don't and this is my daily driver. Just want a little better mpg.

The kit costs about $500. How many miles a year do you drive, what do you pay for gas per gallon. What's your current mpg?

You won't be able to measure any change in mileage. There are a lot of other things you can do though. What engine, gearing, tires, suspension etc. does the truck have?

Back in 2008, when diesel was nearing $5 a gallon, I removed my front drive shaft & put it in diff lock (LT230Q) for several thousand miles that summer.

I SAW NO INCREASE IN MILEAGE !! AND yes I drive more slowly & carefully than your GREAT grandmother.

If you want better mpg get a different vehicle for a daily driver. You can get a cheap civic or accord for less than $2k. After insurance and gas you will be spending less money. And you can prob drop the premium on the rover by decreasing annual mileage.

What if I just wanted to be able to dump the clutch with an open rear diff and aim that rooster tail of mud coming off the left rear tire and absoultly cover my best friends fj 60? Would you sign on for that?

I would. I used to do four wheel burn outs in my D90 in the wet when I was younger.
