patrickkomar Posted October 26, 2010 Report Share Posted October 26, 2010 how would I figure out what spring rate would be right for the back my bike? I'm 6' tall 250 lbs ready to ride. My bike has a 6 over swinger and is a dune only rig. Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted October 26, 2010 Report Share Posted October 26, 2010 how would I figure out what spring rate would be right for the back my bike? I'm 6' tall 250 lbs ready to ride. My bike has a 6 over swinger and is a dune only rig. Get a 9.6kg/mm. The size you need is 55mmx240mm. Eibach or hypercoil can make you any spring you want. On a stock swinger, you'd need about 8.23kg/mm. So with a +6, the 9.6kg/mm spring that is available from Eibach would be the sweet spot for you.

Thanks Matt, hyper put me in touch with another company who deals in olins and they have my spring on hand for a great price! Witch way do you think would be better to rebuild my stock rear shock, have works do one of there Hart transplants or have it rebuilt with the race tech gold valve and race tech seal head and parts?

So Cal Suspension Posted October 28, 2010 Report Share Posted October 28, 2010 I'm not sure who Hyper is, but make sure they are either Hypercoil, h&r or Eibach springs. DO NOT buy a Chinese spring. People who say they have them "custom made", come from China, and the stated spring rates are almost never right. I have a shock dyno, and have dyno'd about 10 shocks with the Chinese springs on them, and not ONE of them had the same spring rate, so just be careful. Some were off by as much as 1kg/mm. Also as far as the revalve goes... I am a works, race-tech, axis, and Fox dealer. I can do the revalve for you for less than half the labor that either of those companies charge, and I have parts in stock, ready to go, minus the spring. I would personally recommend the Race-tech gold valve kit, but not their seal head. I would run the Moose seal head. It runs about $37 bucks, and I have it in stock as well. PM me if you want some more info, and hard prices. I can have it done for you in about a week. Quote Link to comment Share on other sites More sharing options...
patrickkomar Posted October 29, 2010 Author Report Share Posted October 29, 2010 Okay let me reword my last post, hypercoil sent the info I sent them via email to a company called Re suspension Inc and they contacted me saying that they ran the info past ohlins and the spring rate they recommend is a 543lb spring and they had it in stock from ohlins. I'll be shooting you a pm adapter about the rebuild! Quote Link to comment Share on other sites More sharing options...
