Re: Rear End Swap
Easy to do and the simplest and cheapest overall upgrade. The 8.8 mounts up the same way as the 7.5, the only difference in the axle is the size of the differential housing. Just unbolt the 7.5 and then bolt in the 8.8.
You will need to get the cobra flange (about $20) for the pinion though so that the V6 driveshaft will mount to it. That is the most difficult part of the swap because getting the flange set up with the proper pre-load is critical. I took my 8.8 to a rear end shop and had them swap it for me so that I knew it was done right.
