polaris and cat spring rates

[dobson]

does anyone know if polaris and cat rate their primary springs with the same measured preload? i know comet is different and the p90 but i don't know about the p85.

They are close but they are rated at different amounts of compression:
Arctic- 2.562" and 1.312"
Polaris-2.5" and 1.19"
The Polaris drive clutch has a slightly longer shift 1.31" to 1.25".

Good info!

So you say the p-85 shifts from 2.5" to 1.25"? Moving the sheave 1.25"?
