Caught the Bug
I know I know, another PR60/80 thread. Lots on here. I've talked to Offroad Evolution and Dynatrac about the new PR XD60 rear and PR80 rear axles for my upcoming build. The cost difference between the two is less than $400 (as told by the Dynatrac sales rep), so cost is not an issue. Obviously the PR80 is significantly stronger than the PR60. I do not have plans for a Hemi/LS V-8 swap, and if I have engine problems down the road I'll likely just swap in a new/low mileage takeout 3.6. With that said, the XD60 is a high pinion, the PR80 a low pinion. There is a 1" difference in ground clearance between the two. The high pinion should give a better driveline angle and keep the driveshaft higher up out of harms way. The low pinion PR80 is nearly twice as strong. Both have their advantages over the other. Both are practically the same cost. We all know the specs on them.
Which would you go with when thinking about the ground clearance? 1" is the difference between 35" tires and 37" tires, which was a noticeable difference on my last JK. Dynatrac says that the smooth bottom on the PR80 makes it almost immune to snagging on rocks and will just slide right over just about any obstacle I'll encounter. instead of stopping me in my tracks. Has this been the real world experience with the PR80? IS the difference between the two enough to worry about slowing me down on the trail? I love the PR80, but if the extra clearance of the XD60 is a big enough benefit, I'll go that route. Thoughts/opinions? I will be running 40" Nitto Mud Grapplers.
