Very nice, thats a first generation Grand Cherokee ZJ with what appears to be a 2 inch lift and 32 inch tyres, I assume the dana 30's have been updated to dana 44's to cope with the axle stress of the larger wheels.

it is indeed a 2" lift and a longer wheelbase thrown in, front axle moved 2" forward and rear 3" back with longer control arms and yes what are described as 'Beefy' axles. It was bought by Jeep on Craigslist.
