The radiator is an often overlooked part of the engine, despite being integral to a healthy-running vehicle. Replacing your radiator won’t make your car run faster and increase horsepower, but it can help your car survive a good deal longer. But radiators aren’t cheap, unless you can get a really good deal on them.

Speaking of good deals, for today only Downs Ford Motorsports is offering a whooping 50% off the cost of Ron Davis radiators left in stock (plus shipping costs.) That’s an incredible deal, offered only by Downs Ford Motorsports on their Facebook page.

Those kind of savings can go a long way towards making your motor faster, and add up to some serious scrilla. For example, a Ron Davis radiator for a 94-96 Mustang with an automatic transmission cooler usually costs $565, but today costs just $217 plus shipping. There are just four of these radiators left in stock. If you’ve got a 97-02 Mustang, the normally $495 Ron Davis radiator for manual transmissions costs just $185 plus shipping. There are just five of these left.

A radiator for an automatic-equipped Mustang from 1997 to 2002 usually costs $565, but for today only the cost has dropped to $217 plus shipping. That’s a huge discount for a great radiator…but supplies are very limited, so don’t waste time, get those orders in and save some serious money for an upgrade you probably needed anyways.
