OEM toyota hardware to raise your split case breather. This kit allows the transfer case breather to be raised and routed to a higher location.
The original breather sucks air from directly on top of the case. This can allow contaminates and water into the case... assuming your breather is properly functioning. Often times they will be plugged from years of oil and road debris sealing them off. This leads to seals to be blown out due to pressure changes.
You will need to provide 1/4" hose and route it to your preferred spot. Be sure to use oil specific hose. NOT coolant hose.
