A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Confirm the application requires an LQ-2 valve in the front service brake circuit.
✔ Verify the 3/8" supply, two 3/8" delivery, 1/4" control, and 3/8" exhaust connections.
✔ Mount using 5/16" SAE Grade 5 hardware tightened to 17-19 ft-lb.
✔ Apply air-system-compatible sealant without allowing sealant inside the valve.
✔ Test limiting, full-pressure, quick-release, and leak-free operation after installation.
