Im getting the parts together to do the 4.10 gears on my IRS, Im going with a solid pinion spacer instead of a crush washer for added strength and more accurate torque readings , I also was thinking about buying studs ( real cheap 30 bucks) for the main caps for added strength , i was looking at either the trick flow/ summit kit , wondering if anyone has ever done this in their IRS? will I run into problems or will it work just like any other 8.8?
