Have a question. I have a set of Billy’s 5100’s and I’m wanting to order some new springs. If I didn’t want to use my original oem parts what exactly would I need to order??? I’m think all I would need is a strut mount and rubber seal and the strut bushings. Am I leaving anything out??? Going to order some 08+4x4 coils but instead of breaking mine down I’m just going to get them done so I can do a swap, but need to know what I’m ordering before hand. Going to order from ROCKAuto. Thanks
