Rear shocks

I'm ordering rear shocks to go with my AAL - can anybody give me some details on the difference between billy 5100 / 5150?

Right now I'm running front OME 885's w/ 5100's and rear AAL.

Can I run the combo? 5100 front, 5150 rear?

Will the 5150 in rear improve ride / performance over the 5100?

Or is it pointless to spend more money? Any info is appreciated

 

Decided to call Bilstein and ask.

The combo will work.

The 5150's are a more aggressive shock and are for the more "aggressive" offroader. These aren't ideal for the daily driver.

Although the 5150's look badass, I'm going to go with the 5100's in the rear

 

I was just going to say 5150 are nice but like bilstein said you will be fine with the 5100.
