I just checked Geno's and I didn't see any Hy-Tech covers for the front or rear diffs of my 03. I have the 11.5" rear. Anyone know where I can find them. I need to get them since I am almost to the 15,000 mi mark and will changing the fluid. Also, how much Amsoil quarts for each diff will I need and what weight do you guys recommend? Thanks-Steve

 

They do have the rears, they are just not on the site yet. Give them a call. They don't have the fronts out yet.

Part # MH-AA10.5 for the 10.5" cover $ 245.00
# MH-AA11.5 for the 11.5" cover $ 265.00

Thanks Mike, I figured they still had them. I wonder why the front cover isn't out yet? It was supposed to be out this past winter...

I think there are some issues with the rears. They are made for the GM version and dont use one of our holes, leaving it unused. Also there may be a clearance issue with the spare tire or something like that.

 

I believe it is the hole on the very bottm of the axle that does get a bolt, over 20,000 miles and no leaks yet though.

For the tire clearance problem I also believe it was with after market oversized tires. I still have room between my cover and spare with 4,500 pounds of gravel in the bed.
