Dana will be releasing a new CTIS Wheel Valve design that will be compatible with the LMTV systems. The valve will only be sold to OEM for current production. However if there is enough interest we could market a rebuild kit. The advantage of the replacements parts is a new diaphragm that will perform to -35 deg F. and last much longer. The new design is also impervious to water and moisture. Please let me know your interest in this kit and what a fair price point might be. The kit would include the following: New vented lid w/4 screws, new diaphragm, new spring, and a small bracket to protect the lid vent. As this would be purchased through a dealer I could be $100 per valve retail.
