1992 Isuzu Pickup - What is the factory gear ratio?

Postby littlegray » Fri Apr 22, 2011 3:44 am

I'm trying to decide on the best tire size. Does anyone know how I can find the factory gear ratio? It's a 1992 Pickup 3.1L.

Thanks! 8)

Thanks for your help.

Which vehicles have 4.55 gears that are easily found in junk yards?

ALL TROOPERS CAME WITH ONLY 4.55 92-97 12 BOLT

LOTS OF AMIEGOS THAT CAME WITH THE 2.6 HAD 4.55
IF THE AMIEGO CAME WITH THE 2.3 IT HAS A 10 BOLT REAR. AND ONLY CAME WITH 4.10 GEARS

EVEN THE 12 BOLTS THAT CAME WITH DRUM BRAKES ON THE AMIEGO AND THE PICKUP WITH THE 12 BOLT ,A LOT OF THEM COULD HAVE HAD THE 4.55

ALLSO SOME DID COME WITH 4.30

AND A LOT OF THE 2WD ESP THE AUTOMATIC CAME WITH A 4.10 12 BOLT REAR AXLE
MOST ALL THE AUTOS CAME WITH 4.10 AND DISC BRAKES AND THE 5 SPDS CAME WITH DRUMS

ALL TROOPERS FROM 88 THRU 91 CAME WITH THE 4.55 ALL SO EXCEPT THE ONES WITH THE SNOW FLAKES WHICH ABOUT IMPOSSIBLE TO FIND NOW .

That's perfect. Thanks for the information. I'll find a good donor trooper for gears before installing lockers.

THAT WOULD BE CORRECT, THE 4WD CAME WITH THE 4.30 AND THE 4.55 A LOT OF 2WD CAME WITH 4.10

SOME HAD DISC AND OTHERS HAD DRUM BRAKES
