Pistons & Cylinders

LN Engineering's Nickies cylinders look great and perform even better. They are machined out of a specially extruded alloy that is up to 50% stronger, 45% more thermally conductive, and much less brittle than the alloys used by Mahle for cast factory cylinders. With 6.5 fins per inch versus the typical 4 fins per inch on cast cylinders, a phenomenal 60% increase of surface area is achieved providing improved heat transfer. Nickel-silicon-carbide (known as Nikasil), which has a reputation for providing hundreds of thousands of miles of worry-free service, adheres excellently to this alloy, giving top-notch reliability. The finished product is media blasted and acid etched to roughen the surface, further increasing cooling ability by increasing air turbulence. All of these improvements and they weigh less too! Why go back to factory when you can build a cooler-running and more durable engine instead!

AutoTec /RaceTec is a High Quality, Precision Manufactured piston option. That comes at a very respectable price. Our Design Specific Forging allows us to manufacture our parts with less machining time, thus allowing us to keep production cost down. Then pass that savings on to you, the customer. Made out of 2618 (Ractec) & 4032 (AutoTec) High Silicone Aluminum Alloy, it has great wear resistance, a low expansion rate, is very durable, and is very low in friction. These pistons accommodate multiple uses including. Your local auto shop, muscle car restorations, performance street rods, as well as many spec racing classes. They can also withstand mild nitrous kits and small turbo or super chargers. Just about everyone can benefit from the excellent value the AutoTec line carries. Keeping in mind these pistons were originally designed for about 600 Horsepower. In Small Block applications, we have customers that frequently fine tune engines that yield 850+ Horsepower with a bit of Super Charger boost. Bore, Ring Pack, and Compression Distance changes can be made to any shelf part at no extra charge. Meaning that if you do not see your application listed in the guide, we can make what you need without charging a custom price. Every part is made with same high quality machines and tools as our RaceTec line including diamond turned ring grooves, and skirts. Not to mention our parts are 100% made in the USA. We can even provide private labeling / branding for those who are looking to expand their own engine business.
