* Cost: The price of a new OEM proportioning valve might be higher than aftermarket alternatives or used parts from salvage yards.

* Installation complexity: The replacement process for this part may require professional expertise to ensure proper installation and bleeding of the brake system.

* Availability: Depending on the specific model and availability, the part might take some time to source and receive.

* Potential for additional repairs: Replacing a proportioning valve could reveal other issues within the brake system that may require further attention and additional costs.

The decision to buy a Ford 539.fd8f86 Rear Brake Proportioning Valve for 1985-1986 F-350 Chassis involves weighing the benefits of improved safety, proper brake force distribution, and OEM fitment against the potential drawbacks of cost, installation complexity, and availability.
