Center Shock Spring

[jonlafon1]

Do you have any idea what the initial & final rates are for that Raptor spring? I thought I read a post here somewhere that someone determined that the final rate was about 250 (same a stock spring). I am wondering if the initial rate is stiffer than the 90/250 spring that comes stock. I was also considering the 2704-229 Cat 160/260 spring.

I do not.

I am about 185-lbs undressed. Do you guys think the Cat 2704-229 160/260 center shock spring would be too stiff for me on my 17 LTX SE? I ride aggressively and mostly in the New-berry-Grand Marais-Seney-Munising areas in Michigan so there is a LOT of time spent on whooped out trails. I currently have the stock 90/250 spring with minimal preload on it. The sled handles corners great but I am also experiencing the rear bottoming out easy on somewhat hard hits. Hard enough to have track clip marks on the top side of the plastic torsion spring holders. I have the rear torsion springs set on the middle position (these are SRX/Thundercat torsions that have less preload but a higher spring rate than the stock LTX torsions).

Also, when you guys are listing preload measurements (threads showing) on the center shock, is that with the limiter straps set or before the spring/shock is sucked up a little by reattaching the limiter straps?

Are you in the UP now?
Do you want to try my center hpg shock with the cat 160/260 spring on it in your sled?

I appreciate the offer but that likely won't work out. I won't be there until next week Friday and typically ride from Newberry to Grand Marais to Christmas, spend the night, and then ride to Seney and back to Newberry on Saturday.

I just ordered the 160/260 Cat spring from my local dealer for $50. It might not be here in time to get it installed for the trip next week (we leave Thursday mid-afternoon) but maybe for the next.
