teddan Posted October 15, 2012 Share Posted October 15, 2012 I bought a Brian crower valve springer kit. The springs was yellow painted, I just to check with you guys that it only to detect with side should be upwards? I want to mount it in the position on the picture Link to comment Share on other sites More sharing options...
hodge Posted October 15, 2012 Share Posted October 15, 2012 It shouldn't matter which way up you put it. It's probably marked to signify its been pressure tested. Link to comment Share on other sites More sharing options...

Digsy Posted October 16, 2012 Share Posted October 16, 2012 Some valve springs are progressive and have tighter coils at one end. Those should be installed with the tightly wound coils at the bottom. That doesn't look like a progressive spring to me, hence it should not matter which way up it goes. Would have been nice of they could have ground the ends square. Maybe its just the picture...

Chris Wilson Posted October 16, 2012 Share Posted October 16, 2012 (edited) No, that's a Chinese BC spring, they make them from straightened out Chinese Puzzles you know Kauffman eat your heart out.... It'll straighten up in use, (and go soft and take a set, no doubt). It can be fitted either way up, as Digsy says. Stock ones are progressive, to help stop harmonics, the Yanks don't worry about *hit like that Edited October 16, 2012 by Chris Wilson (see edit history) Link to comment Share on other sites More sharing options...
