    Rear-end swap: 8.6" 10 bolt w/3.08 >> 9.5" 14 bolt w/3.42 + 3.42 swap in 8.25" front (or else)

    The avalanche (1500) and Tahoe/Yukon are built on the same chassis. Wheelbas is the diffence so mounting points are the same. 2500 a different animal

    As long as it is a pure sythetic its no big deal. You can change early like 4000 miles. Any of the pure synthetcs will be fine.
