What castor arms? do you want to upgrade brakes at the same time? the only way your going to do this without spending thousands of dollars is to make up a set yourself with weld on sleeves.

sssute sells the kit, he's recently bought out maddat.

what year ute?

Hey madhatter, I do a few different kits to suit 51mm struts, I can supply just the sleeves, locking rings and top hat, or complete struts with inserts, springs etc. We normally use 200B and Stanza struts and shorten them by 2inches.
