yea, it is. 1st set i got from plank (now tom at si) the 1st month he started making link kits. he was the 1st shop to make a link kit. i am only on my 3rd set. i have never broken a bolt or bent one. i have only replaced a few just because of assembly/disassembly. upper heims have been changed, lowers are still the 1st set. i forget what year it was...1995-97????
