Step 1

Unthread the Air Fill Cap counter-clockwise with a T8 Torx driver then set it aside. Thread the  Air Fill Adaptor (PN: 803-01-192) clockwise into the Reservoir End Cap fully to release the IFP pressure (if attached to a FOX high-pressure pump, use the pump to bleed out all air from the reservoir). Remove the Air Fill Adaptor by unthreading it counter-clockwise.

Step 2

Push the Reservoir End Cap into the Reservoir to gain access to the wire retaining ring. Remove the wire retaining ring by pushing the center of the ring down which will cause the ends of the ring to pop up. Be careful not to scratch the IFP bore while removing or installing this ring. Use a small hex wrench to lift the Reservoir End Cap out from the Reservoir.

Step 3

Remove the bearing housing cap and any travel spacers (if present) by unthreading counter-clockwise and removing the two screws with a 2mm hex wrench.

Step 4

Use your 2026 DHX2 bearing housing cap torque tool (PN: 398-01-195) to unthread the bearing housing counter-clockwise. Lift the shaft assembly out of the body. Pour the oil out of the body and reservoir into your waste oil basin.

Step 5

Use the IFP depth setting tool to remove the IFP by engaging the protrusion of the IFP with the tool then turning the tool 90 degrees. Lift up on the tool to remove the IFP from the reservoir.

Step 6

Unthread the set screw in the 2Pos lever by turning it counter-clockwise with a T10 torx. Remove the 2Pos from the eyelet .

Step 7

Clamp shock using Damper Body Clamps (PN: 803-01-545). Use a flat driver to carefully lift up the DSC Housing Cover and remove O-ring. Use the 12 Pin Spanner Socket(PN: 398-01-194) to unthread the DSC Endcap counter-clockwise from the eyelet then set it aside(Note: turn adjuster at least 1 click clockwise before unthreading DSC Endcap).

Step 8

Using a 6mm L Hex to slightly angle and then pull out the DSC Cartridge from within rezi.

Step 9

Remove the Firm Mode Piston using your Firm Mode Piston tool(PN:398-01-190) by unthreading it counter-clockwise. Be careful not to lose the Firm Mode Butterfly Valve and Spring Washer.

Step 10

Clean the Damper Body and Clamps with Isopropyl alcohol. Clamp the Body in your Damper Body Clamps (PN:803-04-355) then heat the body area of the eyelet to break down the Loctite. Unthread the Body counter-clockwise from the Eyelet. Take care as the eyelet may be hot!

Step 11

Clamp the eyelet assembly then loosen up the HSR Adjust Clamp set screw with a T10 torx. Use a 1.5mm hex key to turn the HSR adjuster shaft clockwise (causing the HSR knob to also turn), which will unthread the HSR Adjust Clamp. Unthread the Main Piston Assembly from the shaft by turning the HSR VVC Plate counter-clockwise with a 20mm wrench. Set aside the VVC Assembly. Remove the Bearing Assembly by pulling it up off of the shaft.

Step 12

Pull the Rebound Rod out from the Shaft. Remove the Bearing Assembly by pulling it up off of the shaft, followed by Bearing Housing Cap, MCU Bumper and Bottom Out O-ring. 

Step 13

Remove Compression Valving, Main Piston, and Rebound Valving from Piston Bolt

Step 14

Note: The next two steps only need to be performed if changing the bleed shim.

Use a T25 to hold the HSR Adjuster Shaft to unthread the HSR Adjuster Nut counterclockwise using a 8mm 12point deep socket.

Step 15

Remove HSR adjuster nut, spring washer, valve and bleed shim.

Step 1

Use a plastic pick to replace the all seals on the Bearing Assembly,  with new greased ones from the kit. Verify that the o-rings within the Bearing Assembly have been seated properly. Also replace the Topput Bumper and Back up rings.

Step 2

Use a plastic pick to replace IFP o-ring with a new greased one from the kit. Replace the o-rings on the Reservoir End Cap, Air Fill Cap and Bleed screw with new greased ones from the kit.

Step 3

Install a new bottom out bumper and Bearing Housing Cap (Important: Note orientation of countersink holes). Coat the seals of the Bearing Assembly with a thin film of Slick Honey, then reinstall the Bearing Assembly onto the shaft using 1/2" Shaft Bullet (PN:398-01-253) as shown. Reinstall Rebound Rod into shaft after replacing O-ring with new greased one from the kit.

Step 4

Ensure Rebound Rod is fully seated in the Cam Slot by turning HSR knob to make sure the rod turns and turning the LSR knob counter-clockwise while pushing in on the rebound rod and the knob stops.

Step 5

Reinstall bleed shim, valve, spring washer onto Piston Bolt.

Step 6

Install HSR Adjuster Shaft and thread on HSR Adjuster Nut. Torque to 15in-lb (1.7Nm) using a xx socket and a T25 to hold the HSR Adjuster Shaft.

Step 7

Thread on Piston Bolt and torque with 16mm hex (F-S/P-Se) or 15mm (P-S) to 80in/lbs (9.0 Nm) without the VVC Plate in place.

Step 8

1. Only for P-Se and F-S 

   1. install VVC Plate
   2. Run down HSR clamp and leaf springs using a 1.5mm hex.
   3. Obtain qty 2 .0031" thick valves (example 044-03-080).
   4. Locate holes on VVC plate in middle of VVC range.
   5. Place 1 valve on either side between VVC plate and .900 valve and aligned with holes from step 4
   6. Adjust HSR adjuster shaft so the VVC adjuster nut turns freely and and there is no preload on the leaf valves.
   7. Adjust the HSR knob clockwise 1 click at a time until the leaf springs are aligned to the holes in step 4 when torqued to the specification on the leaf valve stack. Note: Each VVC leaf valving assembly has its own torque specification.
   8. Torque m3 fastener in HSR adjust clamp to 15in/lbs.
   9. Remove .0031" shims

   Note: HSR VVC Leaf Valves orientation is critical and can be found here»

   Note: Turn HSR knob and ensure the VVC clamp nut rotates freely through the range of travel in the VVC plate

Step 9

Replace the eyelet o-ring with one greased one from the kit. Clean threads of body with alcohol. Apply Loctite activator 7649 and red Loctite 277 to 2-3 threads for a full 360 degrees on the body. Reinstall the Body on the eyelet assy tightening clockwise by hand. Clamp the Outer Body in your shaft clamps, then use the Eyelet Torque Tool to tighten clockwise to 35ft-lb (47.5 Nm) torque.

Step 10

Reinstall your Firm Mode Assembly and torque to 160in-lb (18.1 Nm) using your Firm Mode Piston tool (PN:398-01-190). Tip: Using an 8mm fork damper shaft helps center and drive in the lock out piston. Install Firm mode lever and verify detents function properly.

Step 11

Replace the O-rings on the HSC Adjust Shaft and DSC housing Cap. Reinstall your Base Valve Assembly and torque to 20ft/lbs (27 Nm) using your 12 Pin Spanner Socket (PN: 398-01-194). Reinstall Housing Cap Cover. Note: HSC needs to be not at minimum setting. Suggest middle of range or closed.

Step 12

Reinstall the rebuild Shaft Assembly into the Body. Tighten clockwise torque with the Bearing Housing Driver (PN: 398-01-191) to 30Ft/LB(40.7Nm).

Step 13

Coat the IFP with a thin film of Slick Honey then reinstall into the Reservior with the Bleed Screw facing up. Reinstall the wire retaining ring.

Step 14

Thread the Fill-Machine adapter clockwise into the bleed port. Vacuum the shock, then fill with FOX 4wt. oil. Using your IFP depth setting tool (803-00-566), set the IFP depth as follows:

• Transverse Reservoir (all sizes): 39 +/-1.25mm (1.535 +/- 0.05 in)
• Parallel Reservoir (250mm Eye to Eye): 45 +/- 1.25 mm (1.772 +/- 0.05 in)

Reinstall the set screw with a new greased o-ring from the kit and tighten to 10 in-lb (1.1 Nm).

(FLOAT X2 shown in this step, but applies to DHX2)

Step 15

Remove the wire retaining ring from the Reservoir. Coat the o-ring of the Reservoir End Cap with a thin film of Slick Honey then reinstall into the Reservoir. Push the End Cap down then reinstall the wire retaining ring.

Step 16

Use a small hex wrench to align Reservoir End Cap ( port pointed towards rebound end of shock for transverse rezi and parallel to shock axis for parallel rezi). Install the Rezi Fill Adaptor (PN:803-04-357) by threading it in clockwise. Set the IFP pressure to 150 psi. Remove the Fill Adaptor and reinstall the Rezi Fill Air Cap with a Schrader Valve tool, tightening clockwise to 3 in-lb (0.3 Nm) torque.
