looking on sporttruckdirect at the wc lower control arm and it list for a 3" drop just add a 1" drop spring. it does not say to use a new upper control arm. i have ruslow 1200 coils and i only got a 1" drop so could i use the wc lowers w/o uppers. i have seen a few people with my springs,wc lowers, and djm uppers. just curious if the uppers are required. thanks

 

The uppers just correct the ball joint angle (and have urethane bushings).
