Fox Racing Shocks 2.5" DSC Dual Speed Compression Adjuster Piggyback Bridge Reservoir Upgrade

This is a complete bridge. It does NOT include the two o-rings for the bridge to the shock body and it does NOT include the reservoir sleeve or any internal parts for the reservoir sleeve.

If you're converting a 2-1/2" piggyback shock from a standard reservoir to a DSC dual speed compression reservoir, on old 2-1/2" piggyback shocks, they had a 2" reservoir. Eventually Fox changed to a 2-1/2" reservoir. If you're replacing the old style STEEL 2-1/2" reservoirs, you'll need to purchase an end cap clip, end cap, the IFP internal floating piston, and the wear band. When Fox switched from steel reservoirs to aluminum on their shocks, all of the internal parts were also changed because the aluminum reservoir has a smaller inside diameter than the steel reservoir.

Parts required for aluminum reservoirs:


One of these reservoir sleeves:
• 207-81-070-2 = 2-1/2" diameter 7" long requires 813-00-092-KIT end cap kit
• 207-81-080-2 = 2-1/2" diameter 8" long requires 813-00-092-KIT end cap kit
• 207-81-100-2 = 2-1/2" diameter 10" long requires 813-00-092-KIT end cap kit
• 207-81-140-2 = 2-1/2" diameter 14" long requires 813-00-092-KIT end cap kit
• 227-42-080-4 = 2-1/2" diameter 8" long requires 803-00-977 end cap kit
• 227-42-100-4 = 2-1/2" diameter 10" long requires 803-00-977 end cap kit
• 227-42-130-4 = 2-1/2" diameter 13" long requires 803-00-977 end cap kit


• One 038-01-052 wire clip

One of these IFP internal floating pistons:
• 223-00-031 Black nylon plastic non threaded piston (does not use a wear band)
• 805-00-079-KIT Black nylon plastic non threaded piston with o-ring (does not use a wear band)
• 223-00-036 Aluminum non threaded piston (requires 002-00-029 3/8" wear band and 029-00-328 o-ring)
• 223-00-047 Aluminum threaded piston (requires 002-00-029 3/8" wear band and 029-00-328 o-ring)
• 805-00-085-KIT Aluminum threaded piston with o-ring and wear band
• 805-00-066-KIT Aluminum bleed piston with o-ring and wear band (best choice but requires special tool)


• One 002-00-005-B Wear band for the IFP (note that this is 5/16" tall) or
• One 002-00-029 Wear band for the IFP (note that this is 3/8" tall)
• One 029-00-328 O-Ring for the IFP

One of these stickers:
• 024-04-134 Orange and black sticker for coil over or smooth body shocks
• 024-04-133 Orange and black sticker for IBP internal bypass shocks

Notes: A majority of Fox seal rebuild kits have the 5/16" tall soft brown wear bands in them. The 5/16" tall band was for steel reservoirs that had a different IFP. Most, but not all, of the aluminum reservoir aluminum pistons use the taller 3/8" wear bands. For the IFP internal floating pistons, the nylon plastic pistons would be the least favorite. They don't use a wear band, they often break and they're not threaded to set the depth or to remove it from the reservoir. Out of all of the aluminum pistons, the 805-00-066-KIT bleed piston works the best, especially in an internal bypass piggyback shock, but it requires an expensive tool to set the depth or remove it from the reservoir. On a conventional IFP, it's threaded 1/4"-20 coarse thread so you can grab onto it with a piece of all thread to set the depth or remove it from the reservoir. On the 805-00-066-KIT bleed piston, in the center of the piston, it has a small allen bleed screw. That's why it requires a special tool to grab onto that piston.
