LT230 Transfer Case, 1.410 Ratio

This transfer case was purchased directly from Ashcroft in the UK. It's a 1.410 ratio with only about 5K miles on it. After running it briefly on my truck, I decided to go with a 1.2 TC instead. With core charge, shipping, and exchange rate, I paid about $1200. Looking for $500 plus shipping. Local (SoCal) sale preferred.

Good price. Too bad you hadn't been selling about two months ago. I just picked one up from Ashcroft.

Curious, why the change back to the 1.2?

I'm running an HS2.8 diesel, and the diesel just seems to like the 1.2 ratio much better.

Pedro - check your PM.

Funny, I'm running a 1.21 with a HS2.8 in my D110 and I just bought an Ashcroft 1.4 for a little shorter gears, I have a 1.2 with fresh gears and bearings for sale, w/ 5K miles...

Chad - what trans are you running? I have a ZF auto, and it runs much better with the 1.2 TC.

Ryan, can you describe the difference you feel between the two? I have a ZF auto in my D90 with what I believe is a 1.2 and the gearing is pretty high. I went to 4.11 gears in the diffs, but think perhaps a 1.4 transfer case would be good too.

Charles that 1.4 with your 4.11 gears will be very high. I ran that for a weekend because my transfercase went and swapped in a 1.4. Its the equivilant to running 4.75 gears. You have 33" tires right? I would think that autobox with the 4.11 would move you just fine, no?

Now I have a 1.4 with 3.54 gears which is the same as 1.2 with 4.11 gears.

Yeah it's fine on the highway now (rpms were stupid low before) but I still feel like I could use a little lower ratio on the trail. It might just be the feel of the auto though.

You are probably right that the 1.4/4.11 combo would crank my rpms up too high on the highway.

I'm thinking of doing the same switch with a 300tdi manual. I was thinking it would pretty simple to just switch in a 1.2 gear kit? No?

This involves removing the tcase and dissasembling it. Its probably easier and cheaper to find a good used 1.2 to reinstall quickly and still have a complete 1.4 to swap back in

Too funny. I just switched from 1.2 to 1.4 in my 110 with 200tdi. My issue was the 35" tires. I still am going change the axle gear ratio as my heavy truck hates really steep hills on the trail.

Swapping t-case gears is real easy, the real PITA is getting the t-case in and out.

I have a used set of 1.2 gears if anyone wants them.

I am running an Ashcroft Diesel R380.
Chad

------ Follow up post added December 19th, 2010 12:29 AM ------

This is my experience with changing gears in an LT-230.

I'm not a gear box guy but I rebuilt a LT-230 in a couple weekends with some rover buddies that knew a little more than me, it was fun and a great learning experience. I installed it in my Defender and it was nice and sweet for a couple miles, then it became noisy. I did not have the correct load on the bearings. This is the seemingly simple task that can turn into a small Harvard education.

I ran the noisy t-case for several thousand miles until I did the diesel swap. I bought new 1.2 gears and bearings and had a gearbox guy build my t-case and its sweet, but the gears are too tall for me. I think I have $1000.00 in labor and a few to several hundred in parts in the rebuild. Its now is for sale.

When I decided to change to 1.4 gears, My buddy and I bought two 1.4 cases from Ashcroft, everything included at the end of the day cost $1,605.00 EACH with HD cross-pins. Same or less than rebuilding and you have an extra t-case to sell. When buying a t-case from Ashcroft, you are the importer and you must become educated with the importation process BEFORE shipping. This is very important! Ashcroft is a good gear box shop, but they are not in the business to educate you about importation.

Good luck with your gear swaps. I'd be happy to help by sharing my experience.

Chad

Charles low ratio gearing is the same in 1.2,1.4, & 1.6. Only way to change that is to lower your diff ratio's or put a crawler kit in your tcase

Thanks Doug - probably explains why I went to 4.11 gears in my diffs instead of trying this before. Man my memory sucks

Funny, because I didn't see your post and just googled it and found this from ECR's site (thanks ECR), and came here to get confirmation. So thanks for the response in advance!

Sorry for the hijack

This isn't the right thing to do to lower your crawl ratio. The stated ratio for an LT230 transfer case refers to the HIGH RANGE ONLY. The LOW RANGE gearing in a 1.4 ratio LT230 and a 1.21 LT230 are EXACTLY the same. The only difference is in the high range. 1.4 ratios were fitted to diesel D90s and Defender 110s, where the 1.2 ratio boxes were installed in USA Defender 90s and Range Rovers and Discos. To alter your low range you will need a custom low ratio kit for an LT230 like those sold by Great Basin Rovers, or your can change your ring and pinion with a 4.11 gear set or ??, but changing your LT230 will gain you nothing in low range.
