Achieving maximum displacement and structural integrity in an aluminum modular block requires the robust reinforcement that only high-quality liners can provide. At ModMax Racing, we offer the specialized components you need to push your 4.6L or 5.4L engine to its absolute limits. Our premium Ford performance parts are engineered to replace thin factory liners, allowing for larger bores and increased wall thickness to combat cylinder distortion under high boost.

By choosing these Ford engine parts, you ensure your build can handle the extreme cylinder pressures common in drag racing and high-performance street applications. Shopping with us means you gain access to decades of modular engine expertise and a commitment to precision machining that many competitors overlook. While you might be sourcing Ford cylinder block sleeves for strength, the ModMax Racing Big Bore Cylinder Sleeve Set provides the necessary foundation for those gains. We stock these essential Ford replacement parts because we understand that a reliable, high-horsepower engine starts with a stabilized bore. Order today.
