Anybody know if you can buy the tube that threads into the shock body On a pro 40 center shock. The tube were the floating piston is. 19000 miles I think I need a new one.

I suppose the body could wear to a point that the IFP might not seal properly. I take it the shock doesn’t have a second reservoir with the IFP. All one unit within the main shock body? I have found when installing the IFP, there’s always less resistance where the IFP rides inside the shock body. Slide the IFP in and you can feel where it gets easier to push it down once it hit the worn area.

What’s up with it? I’m no mean a shock expert but rebuild my own stuff so I’m just slightly dangerous with 300 psi of nitrogen!!

Yes this is a pro 40 shock so it has a remote resi. What's up with it is the inside bore is all scored up. Not sure how but there was lots of air or nitrogen in the oil side of the shock. With very little nitrogen pressure floating piston was moving like two inches causing massive scoring. Floating piston looks good yet. Called all over today could not find one, hpg doesn't sell them. Found hygear suspension where they make their own but they won't be in until the fall. Then it hits me I got an old c36 shock from my 08 MXZ. Took it apart and it's in perfect condition. Also has the high low speed adjuster. Swapping them both to my pro 40 shock. The high low speed adjustment is a stab in the dark as far as setup. Took it apart and it has its own shim stack and spring. Oh well this is how you learn.

Hygear sells a replacement reservoir for the 40? My center has the same problem with scoring where the ifp rides

Yes hygear says they have their own manufactured but they will not be in stock until the fall. Can't believe hpg doesn't sell them. seems like they just want to force you to buy the whole thing.

Have a shock guy mill the cap and replace the ifp with a bladder from a motor cross shock. Awesome upgrade.
B-line control in mn. Can do that for you. No stiction from the piston gives suspension a deeper feeling.
