Bilstein 5150 series shocks

[wegel11]

Is anyone running the bilstein 5150's. I'm thinking about buying them, but i am wondering if they are worth it. Also, any size/length recommendations for a 72' Chevy k20 with 4'' lift.

I'm running the 5150's on my rig right now and I absolutley love them. I took of the pro comp shocks and install the ford superduty shock towers on the front and used the 14" stroke shock on the front and I made a crossmember for the rear above the axle and made some mounts for the top side of the rear axle and I'm running the 10" stroke one's on the back. I highly recommend Bilsteins. My shop is a dealer for them and we sell alot of them.

I have them in the rear of mine and 5100's up front.14's F/R
5100's and 5150's are the same shock except the 5150 has an res. mounted on it.
Buy them as long as you can and get the 255/70 valving.

I have decided that im goign to get the 5150's, but i dont know what size. I just measure the current shocks, unloaded and on level ground, and the fronts were 20" and the rear 22" (from eye to eye). Can one of you suspension guru's help me pick a length of shock to get.
