Hey guys im wanting to upgrade my rear differential to something a little stronger, im looking and either getting an explorer 8.8 LSD w/ 31 spline axles and 4:10's
or a Ford 9" LSD with 31 spline and 4:10's

the reason i want the expo axle is because of the rear disk brake, but i hear they are hard to find with an LSD.. so i was wondering what the code for the 31 spline LSD with 4:10s is?

i would like the 9" because well they are bullet proof and i plan to throw a built 5.0 in later on, so if i go that rout what car or truck has a 9" with the closest hub face detentions and 4:10s?

or is there any other options that might be better for me?

Thanks for the help and ideas,
-Andy

 

Expo's are easy to find with l/s, but finding it with that and 4.10's is hard. Nine inch is no where near bolt on and as far as I know there isn't anything close to stock dimensions for our rangers.

 

im going to start to look for a expo with 4:10 and an LSD, dose anyone know the code for this axle?

and also is an axle out of a open diff interchangeable with an axle with an LSD in it, both 28 spline?

 

Explorer

Code Description Ratio

41 Open 8.8" 3.27
43 Open 8.8" 3.08
44 Open 8.8" 3.73
45 Open 8.8" 3.55
D1 L/S 8.8" 3.27
D2 L/S 8.8" 4.10
D4 L/S 8.8" 3.73
D5 L/S 8.8" 3.73
85 3.55C
89 (1992-1998) 4.10C
89 (1999-2001) 4.56C
F5 3.55L
K6 4.10L
L - Limited Slip Differential
C - Conventional Differential

 

thank you!

 

so essentially, if you find a 4.10 8.8 it's a l/s?

(with the exception of the k6 code and 89 code, as that doesn't spesify open or not or 8.8 or not)

 

looks like it!

 

BTW, most explorer axles come with LSD. I got mine for like $200-$250 with brakes and everything.

 

with 4:10s?

 

Yes it does...K6 is LS and 89 is open

 

ok guys i finally found a D2! now can anyone help me find the leaf mounting brackets to weld on the axle? and should i keep the same pinion angle or should it be diffrent?
