I think I want to upgrade my front diff/CVs, and rear 10 bolt.... eventually this truck will roll 35" tires and after reading many posts in this, and other forums' off-road sections... it is clear 35" tires will brake on the 1500 power train.

is it easy enough to, say, gut a K2500 suburban with a 454 for its power train and bolt it into my blazer?
i figure theyre the same vehicle minus 2 doors... and the beefier CVC axles and rear diff would be totally bomb proof when the hits the fan ....
not to mention braking overkill. which is always good.


thoughts?

I thought a k2500 front diff was different and does just bolt up to the k1500.

It is a different and bigger setup. The track would be wider, and all of the bracketry would have o be custom fabbed since the frames are different. Along with custom ucas and lcas to accommodate the added track width. The rear end is a cake walk compared to the front, plus it's a fairly common upgrade .

So the front end has a wider track than the rear end of a k2500? I thought a k2500 rear was a bolt in swap for a k1500. I also thought the track width was same but the mounting points were different.

i need to see some photos to illustrate this.... I always thought the frames were the same, but the axles were different... back when things like "engine and transmission options" existed... case in point, the chevy 454 SS... same truck could get 3 different engines and/or transmissions... (of course that was never 4WD)

The frames are different the rear end swap isn't quite bolt in and you think the "454" SS had other engine options besides the 454? Lol

As stated before, the upper control arm frame mounts are wider on the 2500 than the 1500.
