What kind of sled..M8..M1000. You will probably have to take them out unless the previous owner never changed them. If its an M they should have been sent from the factory with the 6-9K specs.
Yep looks like they are 68's. So for 3000-6000´ on a stock M8 what should I try first, don't they spec 72g or 73 for the 09's? I have the yellow/gold primary and orange secondary springs. By the way, does missing paint on the springs suggest they may be binding?? Noticed it on both springs....
