What is the difference between a NP218 and the NV242 HD AMG? Does anyone have any links to technical specifications for these t-cases?

The NP218 was used in the military HMMWV (too light), the 242HD AMG was exclusive to the H1 civilian, but now the military has been updating the older HMMWV's to it. There is a kit for the swap.

You say that the 218 is too light. What do you mean by that? Do you mean that it's weak? Where can I find the specs for the 218?

I'm thinking about putting a 218 in a jeep. What do you guys think?

The 218 would be fine for a jeep, but since the HMMWV was going up in weight, the t/case was just too weak for the added stress.

no... the 218 was used in the Civilian 92/3 models with the 6.2L engine... the input / output splines splines are different with the THM 400 and the 4L80E and therefore they are different on the t-case as well. The 218 will work in a 6.5L TD just needs new splines. THere was a rpoblem with the 242's in 95 when the gassers were built, they were actually causing problems with the internal gearing and they had to harden the gears.... the 242 is newer technology using planetary gears where the 218 is still using differentials...

I’ve always used this 'rule-of-thumb' when it comes to T-Cases originally installed in HMMWV/HUMVEE/HUMMER-H1 on AM General's assembly line;

All those with a GVWR less than 10,000 lbs. got the 218’s and all 10,000 and above got the 242’s.

That of course would mean all Civilian HUMMER-H1 got the 242’s.

Only 'situation' I recall with the 242 used for the '95 Gasser was it required a "beefed up" mainshaft due to increased spike torque (vs. the Diesel). FYI; 242’s since first used by AM General in 1990 on the HHV (Heavy Hummer Variant) have been in an almost constant state of change….some very minor changes…and some very major.
