All 2st WP shock help

Hi does anyone have knowledge or manual for early 90`s WP shock called somewhat Super adjuster (pink piggyback) Not sure if mine have all the parts in piggyback, like its have 1 valve only and no nipple...
And also can you still get bushing for it?

Good shock. Rebuilds well, but parts are getting scarce.

If it's the early seal head you can get a complete replacement seal head from MX-Tech. They're about $70. If it's the late seal head you should be able to get the 14mm X-ring, bushing, and dust seal from them as well. While you're in there, replace the large O-ring on the reservoir piston with a Viton 35x5mm.

Seems mine would late style , but what about pressure in the piggyback?

Crack open the reservoir bolt, nitrogen will bleed out. To recharge I use Race Tech's bolt that you fill with a needle.

the early 90's came with a Showa, not sure about a WP fitting that
does yours have one now??

Greg, the 1990 models had a Duo shock.

so is that made by WP?
the earliest Spaghetti Husky I had was a 92, so not knowledgeable in the 1990 model

Just post a photo of your shock and we can get with it...
