These 2.4L long-rod piston kits were designed to increase reliability and power from the standard 2.3L & 2.5L Duratec engines be lengthening the rods to decrease cylinderwall loading and friction. The 2.3L engines come from the factory with a 6.094" rod and the 2.5L come with a 5.975" length rod. Both of th3 2.3L and 2.5L engines use different size wristpins as well. We've gone with a 6.136" (+4mm) H-beam rod, and shorter 1.098" compression height piston to reduce the stress on the rods and crank. Most of the other options on the market are tailored around the OEM 2.3L 6.094" rod length with a .827" wristpin because that's what is commercially available, not what's best. They will tell you that you don't want to use a shorter piston because it requires an oil ring rail, but for 20 years the aftermarket has proven that there is no durability drawback. The reason the OEM's don't use oil ring rails is because they are an added cost, and require a small amount of additional time during install (both of those cost less than $5/set, but over 100's of thousands of engines that adds up to millions of dollars saved by the OEM for not using them). Our motto on stuff like this has always been, "If it's worth doing, it's worth doing right"! We don't worry about saving $10 when there is a proven performance gain at stake!
