The splitter valve uses air pressure to split each gear (high/low) in multi-speed Roadranger transmissions, giving you extra ratios without a separate shift lever. Over time, internal o-rings wear out or the housing can leak, causing hard shifting, air leaks, or failure to split gears. This kit replaces the worn valve body and seals, restoring proper splitter operation. It includes the housing, fitting, o-rings, and lubricant needed for a complete rebuild.
