king superlows... whats the deal with shock lenght, the supplier in perth says they use a monroe shock thats standard lenght cos Ultima havent made short ones for the e-series yet..

pedders do. but fit their springs (not used so much for kings)

theres concerns about how long normal springs will last, and if it will hit bumpstops, driveshaft on body, and even using medium age shocks on lower springs, (operates at diff range and roots it faster)

currently i have the ford heavy duty (same as pedders i think) in the rear. standard length and shorter shocks in the front both with superlows.

the rear is of more concern ive heard, so whats the best way to stop rapid wear, dangerous driveshaft damage or crappy bumpstop travel

It is a good idea with superlows to get shorter struts so the shock doesn't bottom out. Bumpstop travel - don't go over speed humps fast, harder shocks or get higher springs? Can you see the driveshaft rubbing against the tunnel? Or any vibrations? Or are you just assuming..
