I installed Synergy's lower shock mount/guard set a while back and it just barely worked with rear Billy 5100s mounted to the stock upper points. Added about 1/2" of stop to ensure they weren't bottoming out. On mine to relocate the upper mounts with Synergy's kit meant mving the track bar back, and to move the track bar back meant losing the muffler and getting something like an MBRP.
