I am going to change the fluid in both diffs and my transfer case. I figure I might as well do it right and go synthetic and not have to worry about it for a while. Anybody Know a good source online to buy this stuff? Also what weight is recommended?

These guys: www.synlubes.com have never given me problems.

 

I've had good experience with www.myoilshop.com

 

You can contact Redline Oil for a dealer near you or an online seller they will give you the recommended oils for your truck too

Does anyone have any experience or would recommend the "Shockproof" Gear Oil that redline offers?

 

I order Redline through Summit. they have a $7.95 handling fee and free shipping, comes in handy on the heavier stuff like oil and wheels

 

I do. I have used Redline products, for over 20 years in my race shop and street cars. IMHO the Shockproof is one of their most impressive products. I am not sure on correct weights for our trucks, but that is because I just bought my HD2500 only 2 weeks ago, but i have used everything from the SuperLight to the Heavy in different applications. Excellent products for reducing wear in the drivetrain. I will eventually be converting to it in the Dodge.

 

Which Redline products are y'all putting in your 5 speeds?


Thanks
