2500 is what ST and others claim I have Fox RC 2.5 and they have a little over 3000. I just noticed the other day that they are showing signs of a needed rebuild.

 

Just rebuilt 15 xp1k front Walker Evan's shocks with 3600 miles on them. Found out by surprise the charge was mixed with the oil when I let minimal pressure out of reservoir, removed Schrader valve then removed the reservoir snap ring and cap... pow! IFP and end cap went flying. Second shock

didn't have this issue.

 

Same here... although i went nearly 6000 miles on my Walker Evans. Removed shrader on driver's side rear and normal hiss and spitting some oil, but couldn't move either cap to remove inner ring. Put reservoir in the press, removed clip and relieved the pressure on the jack and BOOM! shock oil everywhere.

Both rears the nitrogen mixed with the oil. Lesson learned, I won't go as long on rebuilds next time.

 

On my xp1000 I had a front shock start seeping this spring at 2400mi. Bought a kit for both fronts from Rocky Mountain ATV ($70 a piece) and some shock oil (3wt Maxima). Did the rebuild and things have been fine except the other day I see a rear is seeping slightly. As I read on here, I realize I probably should've put 10wt in the front and Maxima may not have been a good choice either. Also, the kits for the rear were $20 a piece through Walker Evans vs $70. Interestingly, my shocks never lost much pressure before rebuild. I see that @rsarffs is using Polaris fluid. I've been tempted to go with the Amsoil 10wt shock fluid. As I shop, I also wonder if there is a difference between shock fluid and fork fluid. As far as interval, my fronts lasted until 2400mi and the rears until 3100mi. I'm interested in what others are using for shock fluid both brand and weight.

 

@Flingit1200s
we have a resident oil expert @dafish. ask him about the differences in shock oil

 

Used polaris gas shock 10w. Now 125 psi charge with what I have till I fill nitrogen tank. See how it works out...

 

I ordered Redline 10wt shock fluid and plan on changing the fluid in the fronts and new seals and fluid in the rears. When it comes time to recharge, I may go with 200psi.

 

We just had our done at just under 3000 miles. 1 was all but dead, 1 was seeping and 2 were fine. Hadn't really noticed a problem, would bottom 1 out on hard hits at times but feels much better after having them gone through.

 

Who did you have do the work?

 

Compression and rebound are back! From soft to hard setting the front shocks are like new again. No more squishy aerated pogo stick shocks. These are the tools from Rocky Mountain Atv and got Schmidty Racing Suspensions nitrogen fill gauge and shock seals. Bottom tools I already had but welded the allen to a small socket for IFP bleed screw.

 

On second shock, I backed out bleed screw slowly through Schrader valve hole with towel over cap and let pressure out before removing cap snap ring.

 

I hear ya. I had the shraders completely removed, but the IFP was jammed against the reservoir cap. On the 2nd rear shock I wrapped a towel around the shock in the press.

Side Point: the service manual is completely wrong on Walker Evans for a 2018-2020 XPT. They mention a threaded dust cap, but mine were press fit with an internal clip on the seal head.

 

Where you put nitrogen in.....
The end cap of reservoir is just c clip o ring.
