Manley Performance components from Modern Automotive Performance will give the spirit of a classic American muscle car to your Ford, Chevy, Mitsubishi, Subaru or other sport compact model.
Our staff of gearheads has decades of collective experience, but none of us have been around as long as Manley Performance, which was founded in 1966. The founder of the company cut his teeth in performance racing by rebuilding a 312 Ford V-8 engine and tearing up the streets and highways of New Jersey in a ’56 T-Bird. Parts from Manley Performance have pushed classic names in racing to legendary status.
The company has stayed relevant all these years by keeping its commitment to high standards of quality and performance. These crankshafts, pistons, valves, springs and connecting rods are forged from the highest quality metal using precision engineering and machining.
If you are rebuilding the engine on your Mitsubishi Evo 8/9 or X, Subaru WRX or other performance vehicle, Manley Performance has internals crafted specifically for your car’s standards and specs.
What do you drive, and how do you want to drive it? At Modern Automotive Performance, we’re your personal pit crew, so if engine internals are in your future, contact us today and we’ll point you toward Manley Performance components and parts that meet every single demand you have. Whether you transport your project car to the track in a trailer, or your car is also your daily driver that needs to handle regular roads, Manley Performance parts will get you exactly where you want to go.
You’ll love our prices at Modern Automotive Performance, as well as our low shipping rates and Loyalty Rewards program. You’ll also appreciate our immediate order packing: We get started on your order as soon as you place it. That way, you can get to work faster, and get your project car back on the road where it belongs.
