Chev axles under Grand Wag

[RoofPrints]

I am being given some axles from a full-size Blazer. I believe they are 3/4 ton, but not sure. Apparently they are geared lower than the Wag, are somewhat built, and have disc brakes all around. What are pros/cons of converting? First, I need to see if the front is a driver's drop, but other than that I don't know what to consider. I know they are wider, but how much? Would the front be set up for spring over, and if so does that mean that I need to get RiverBeast's kit before I can use it? Finally, how would the strength/durability compare to the d44? I plan on using it for a combination driver/play rig, so I want some strength, but it doesn't have to be extreme. I have 32s now, and wouldn't plan on running anything over 35s. Any advice or info is greatly appreciated.

I don't know much about GM axles but the strength should be better than the 1/2 ton axles in the GW. They will be wider by a few inches on both sides.

Disc brakes on the rear axle may mean a different master cylinder and proportioning valve to accomodate the 4 wheel disc system. Brake lines at the axles may have to be changed. Emergency brake cables probably won't fit the GM disc brake rear axle.

Its likely both driveshafts will need to be changed in length. The u-joints at the yokes may also be different between your 1/2 ton axles and the 3/4 ton GM axles. Shocks may need new mounts.

blazer axles will not be any stronger then yours, the rear is weaker do to it being a c-clip axle. Plus the drop for the front axle is on the wrong side (GM is pass side front dif).

If they are 79 and older axles, it will be a 10bolt/12bolt. If its an 80+, it will be a 10 bolt/10 bolt.

Front axle will be SOA, so you will gain lift, but you need a transfercase with a pass drop. And they will be 3.5" wider on each side.
