How are they worked out?

I’ve got a 450×3.25 on my downhill bike at the moment, think its too hard for me. Mojo website says i should be using a 350llb spring.

What do the ratings actually mean? I understand the poundage weight but what does the 3.25 mean, looking for springs and there is allsorts of combinations.

If I look for a 350/400 x 3.25 should it fit ok? or do they have different spring lengths too?

I’m pretty sure the 3.25 is the length…

EDIT: so yes a 350/400 x 3.25 would fit

ah thanks.

3.25 is the shock stroke so use the same stroke or you’ll bind the spring before the damper bottoms out.
