Any lift increases cv angles unless you are dropping the diffThe number 5 setting on the Bilstein 5100's will give you 3 inches. 2" on the shock and 1" on the coil. Bilstein says not to go higher than the 5 setting on Rams with the ORP. Plus the suspension will be much better than a spacer type. There will be no change to the CV angles. The 5100's are not the best solution to upgraded suspension but one of the least expensive. They are valved for the higher center of gravity from the lift as well as larger tires. With the tires aired down in the dirt they offer a fairly plush ride. However, after a few hours of hard driving off road they start to fade as they get hot. Then it's time to pull over and have lunch while they cool off. That's the down side to not having reservoirs. Good luck on your choice.
