KAVENZ VHP X SHOCK EXTENDER TECHNICAL DATA

SAFETY

• Always use a calibrated torque wrench and respect the torque values in this manual.
• Use only the hardware supplied with the extender. Do not mix in parts from other products.
• Never ride the bike if a part is cracked, bent, deformed or shows play.
• Do not modify, machine or file any part of the extender.
• Wear eye protection and work on a clean, stable bike stand.

COMPATIBILITY

Choose the extender that matches the eye-to-eye length of your shock. Both versions are for trunnion-mount shocks supplied without mounting hardware.

Check your shock's eye-to-eye length before ordering; it is printed on the shock body or listed in the shock manufacturer's documentation. 

INSTALLATION

1. Clean all parts. Degrease the shock eyelet, the extender bores and all threads. Threads must be clean, dry and free of old threadlocker.
2. Fit the flanged spacers (A). The shock eyelet must be free of any mounting hardware. Insert one spacer into each side of the eyelet.
3. Position the extender (B) on the shock. Align the shock eyelet with the upper bore of the extender.
4. Install the shock extender bolt (C). Apply medium-strength threadlocker to the thread, insert the bolt and tighten to 24 Nm.
5. Grease the shock mount bolt (D). Apply a thin layer of grease to the thread.
6. Mount the assembly in the frame. Align the lower bore of the extender with the frame mount. If your shock has a piggyback reservoir, it must point toward the front of the frame. Insert bolt D through the frame mount and the extender and tighten to 8 Nm.
7. Connect the trunnion end of the shock. Attach the shock's trunnion mount to the rocker as described in the frame manual: 12 Nm with medium-strength threadlocker.
8. Check for clearance. Cycle the suspension slowly through its full travel and make sure the shock never touches the frame. We recommend removing the coil spring or releasing the air for this check.
9. Set up the shock. Re-inflate the shock or reinstall the spring, then set the sag.

Let the threadlocker cure as specified by its manufacturer before riding.

TORQUE SPECIFICATIONS

Never exceed these values. Over-tightening can damage the threads, the shock trunnion or the shock mount.

CHECKS AND MAINTENANCE

Before the first ride, check the full travel with the shock deflated (air shocks) or the spring removed (coil shocks):

• Compress the rear suspension slowly through its full travel. Nothing may touch the frame, linkage or tyre.
• Check for play by lifting and pushing the rear wheel. No knocking or movement at the extender.
• Re-check both torque values after the first 2–3 rides.

Regular maintenance:
