I am sorry for the dumb noob ?s right now but could use some advice

Have: 92 XJ limited with RE 2in BB with 32 9.5 TSL's and a NP231 that lost 4 low.

i have another NP231 to go into the jeep but thinking that i should do a rebuild before i put in in the truck with an SYE and crawler gears. Any recommendations on what to get to upgrade it before it goes into the jeep.

I am also blessed with the Dana35 rear so I want that gone ASAP. I know the 8,8s from an exploder will work. what years should I look for. Also would like to lock it and figure on new gears for 35s down the road (something that wont hate me with the 32s now, i know might be a stretch)

For the dana 30 front, options to get it a little stonger with out killing my wallet and whats a good selectable locker.

Thanks in advance, drew

I cant help you on the TCase.

Look for a post 95 8.8 because they have the disk breaks, also be aware that many 8.8's are 4.10 gears so unless you have 4.10's up front you will need to think about what to do.

For the d30 I would recommend upgrading your shafts to increase its strength. With upgraded shafts the d30 can handle 35's. Locker wise, I am an ARB fan.

i figured on doing the front to match the rear for gears go, arb would be nice but might be out of my price range

Kyle

All selectable lockers are going to be right around the same price range.

I agree with Kyle on the T/C thing I would just change the chain and put new seals and of course the mainshaft has to be changed for the SYE. I've only done one but an extra pair of hands and the FSM came in pretty handy.

The 8.8 did come with 4:10s but I think in the smaller engined versions, so look for a four banger (if that was an option) Not much of a Ford guy. The exception is their rear ends 8.8 for the Jeep and 9" for the race cars.

The D30 needs new axle shafts, as Kyle indicated, not just new but Alloy shafts. The locker carriers accept higher spline count axles so get the carrier first before investing hundreds in axle shafts,which won't fit if the spline count is different.

Those things being accomplished you are then good to easily about 38 inchers.

ok didnt know that, i though the OX ones were a lot lower if they are the same price then maybe ARB is the way to go, because i am going to do an OBA system at some point

Irongrave

would you keep the stock gears in the t-case or would you regear it (its going to be a tail rat and very rarely if ever driven on the street

BlueXJ

You got me. I was unaware that different gears were available for the 231J transfer case!

Fizzed yur spelinz tu.

Depends on what you wheel.. As for after market gears for the 231, the only one out there is the 4 to 1 low kit from Tera Flex. Other than wheeling just rocks there is no reason to go that low. I'd say stick with the stock gears but upgrade to the wide chain and 6 planetary gear set. Both parts will work in a Jeep 231 and can be sourced from a S10 pick up..

Its going to be doing a lot of rocks and some light mud. so i need the GM planetary and chain along with an SYE
