I've been reading thru posts for an hour now, saw one user had lots of luck removing the one helper and going to cal tracs. My parts truck had a set of axle under leaf Lakewood traction bars in it. I'm already running 275/60/15 Drag radials. Anyone tried these Lakewood bars? #21715 is the Lakewood number i found at summit racing, i have these. Another question, any benifit in both shocks being behind the rear?
