just ordered the 418 HD BLACK 13" from direct harley parts -- their last set -- for 409 SHIPPED! -- good deal -- then i ordered my front spring kit from starcycle on ebay for 86 shipped -- good deal -- we'll see how it goes!!!You might be able to find a set of the 418s, but only from distributors or Progressive, possibly a shop somewhere. HDs are nowhere to be found. Progressive says they will not have the ability to rebuild these if they get blown, but will do some deal to upgrade. There are no parts to build any more to be found. I decided on the 440's, figuring I'll be adding lbs, not shedding, in the future.
