Umm, idk where the hell it is... But i searched... Double check these with your manual!

In the front: SAE 80W-90 Axle Lubricant.

In the rear: SAE 75W-90 Synthetic Axle Lubricant.

In the tranny: i think your manual will call for Dexron iii but i think you can use vi! Someone correct that if not...i think they were built to blend and vi supersedes...

You can cehck the owners manual and it will tell you exactly what you need to use for all the components as well as the amount you will need. If you have lost or do not have an owners manual you can go to the home page of this website and there is a list of the owners manuals down towards the bottom. You can click on the one for your truck and open it up. You truck has the transfer case that takes the special GM only lube.

75W-90 synthetic front and rear. GM revised the front gear lube use to use 75W-90 synthetic, see below. All you need is a GL5 rated oil, the GM spec is for a GL5 gear lube. There not going to tell you that or you will not buy it from them.

API GL-5 Clearing up the confusion
•API Category GL-5 designates the type of service characteristic of gears, particularly hypoids in automotive axles under high-speed and/or low-speed, high-torque conditions. Lubricants qualified under U.S. Military specification MIL-L-2105D (formerly MIL-L-2015C), MIL-PRF-2105E and SAE J2360 satisfy the requirements of the API GL-5 service designation.


What ever you do DO NOT use a Limited Slip Additive in a locking rear differential. The use of any additive in locking rear axles (G80) is not recommended. Rear axle additives are designed for use in limited slip differentials which are normally installed in cars. All light duty trucks equipped with RPO G80 make use of a locking differential and the use of additives will delay the engagement of the locking mechanism and may decrease axle life.
