the UPS guy brought me my custom R1 shock this afternoon. man, what a beauty. stock spring on right.
i sent my stock R1 with the OEM spring still mounted over to Cannon Racecraft (http://www.cannonracecraft.com/
) after talking by phone with Tony, the shop foreman at Cannon. they hadn't built a spring for this shock previously, and i wanted a spring built to this specific shock, not a generic spring that might need extra collars. Tony wanted the whole shock, so i put it in the mail thursday, a week ago.
i called Cannon at 9am the following monday, and caught up with Tony just as he was opening the box. i wanted a 16kg/mm or 900lb/in spring built, and Tony replied "let me check a few things and i'll call you back".
at exactly 11am, only two hours later, Tony is back on the phone "your spring is done and i sent it over for powdercoating. tests at 16.1kg/mm, say 900lbs/in". it took two days waiting in line until they powdercoated a batch in gloss black, but the elapsed time in the Cannon shop for this custom spring was only three days. talk about smokin' service from Cannon Racecraft, thanks Tony.
Tony kept the spec sheet for this spring, so if you want a custom R1 spring you can have it built to just about any rate and mailed directly to you. just call Cannon, and ask for Tony, he'll fix ya up.
the spring cost $109, powdercoated in your choice of color.
i still need to bore the bushings, but exclusive of postage, this custom shock has cost a whopping $134. not too bad.
i thought i better add a post script: the R1 shock i am using is a 2008 model. there are some differences in the R1 shock over the model years, and i am not 100% sure all the stock springs are the same. verify first, or you can send Tony the whole shock, as i did.
