Will this fit my 2.3L Ford Escape?

It fits 2.3L and 2.5L Ford and Mazda four-cylinders, including the Escape, Fusion, Transit Connect, Mariner, Milan, Mazda 3, 5, 6 and CX-7. Confirm your engine code and that the block is bored .040 over before ordering.

Do I need to machine the block?

Yes. These are .040-inch (1.00 mm) oversize pistons, so the cylinders must be bored and honed to the piston-to-wall clearance in the service manual. They will not drop into a standard bore.

Are piston rings included?

The listing does not confirm rings, wrist pins or clips. Plan to buy a matching .040-over ring set and check the box contents before assembly.

Is this set good for a turbo or performance build?

No. These are hypereutectic cast pistons intended for stock compression and normal driving. For boost or high rpm, use forged pistons.

How much does the set weigh?

About 12.25 lb for the set of four, roughly 3 lb per piston.

No price was listed, so there is no history to judge. Compare the set against other .040-over piston kits for the 2.3L/2.5L before buying.

Our take on the DNJ PRK484.40 Piston Set

The DNJ PRK484.40 is a set of four hypereutectic pistons in a .040-inch (1.00 mm) oversize, made for Ford and Mazda 2.3L and 2.5L four-cylinders. It fits the Ford Escape, Fusion, Transit Connect and Focus, the Mercury Mariner and Milan, and the Mazda 3, 5, 6 and CX-7. The .040 oversize means the block needs to be bored and honed to match, so it is a machine-shop rebuild part, not a drop-in replacement. It is a low-cost option for a stock rebuild; no price was available for this listing, so compare it against other oversize piston sets before buying.
