Fox Dhx2 Spring Calculator Fix 95%

Note: The official FOX calculator also factors in the bike’s rising rate curve, so always verify the official output first.

Spring rate = (Rider weight × Gravity (1) × Leverage ratio) / (Shock stroke × Sag) fox dhx2 spring calculator

A: Yes. FOX SLS springs are the same rate as standard steel springs (e.g., 400 lb/in is 400 lb/in). SLS is just lighter material. Do not change your calculator input based on spring material. Note: The official FOX calculator also factors in

FOX recognizes that spring rate is subjective. A faster, heavier hitter needs a stiffer spring to prevent bottoming on big drops. A light trail rider needs a softer spring for small bump compliance. SLS is just lighter material

= (180 × 6.25) / (2.25 × 0.30) = 1125 / 0.675 = 1666 lbs/in → divide by leverage ratio again? Wait — correction.
