Automotive Performance Push Rods: A Comprehensive Buyer’s Guide
As a car enthusiast, you already understand that performance matters. That’s why you’re looking to upgrade your push rods to get the most out of your engine. But with so many options available, it can be hard to determine which push rod is best for your car’s make and model.
In this comprehensive buyer’s guide, we’ll dive into the world of automotive performance push rods. We’ll cover everything from materials to lifter compatibility and help you make an informed decision when it comes to buying the right push rods for your ride.
Materials and Construction
When it comes to performance push rods, materials matter. Most performance push rods are made from either chromoly steel or titanium due to their strength and durability. Chromoly steel is an excellent choice for higher horsepower applications, while titanium push rods are lighter and ideal for high RPM engines.
Construction also plays a crucial role in push rod performance. Rolled push rods are more cost-effective but are not as durable as forged push rods. Forged push rods are stronger and can withstand higher spring pressures, making them an ideal choice for high-performance engines.
Push Rod Length
Push rod length is another critical factor in achieving optimal engine performance. The length of your push rod can affect valve train geometry, which can have significant consequences on power output and driving experience.
It’s essential to choose a push rod that works with your engine’s lifter design and valve train geometry. Many push rod manufacturers provide calculators to help you determine the optimal length for your engine, giving you precise measurements to consider when buying.
Your car’s lifters and their compatibility with your chosen push rods is an essential factor to keep in mind when buying. Hydraulic roller lifters work best with lighter push rods due to their lower stress on the valve train. On the other hand, mechanical roller lifters require a more rigid push rod to function accurately.
It’s important to match the lifters and push rods to achieve optimal camshaft and valve motion. Incompatible lifters and push rods can lead to critical engine damage, making it essential to do your research before buying.
Push Rod Diameter
The diameter of the push rod plays a critical role in its strength and weight. Smaller diameter push rods weigh less but have a lower strength threshold than larger diameter push rods. Conversely, larger diameter pushrods can handle more stress but have increased weight.
Choosing the right push rod diameter is critical to prevent bending or snapping, which can lead to engine failure. Always consult with a trusted professional to determine the proper diameter to use for your car’s engine and application.
Push Rod Coatings
Push rod coatings can help add strength and durability to your push rods while also providing excellent heat resistance. Generally, popular coatings include black oxide or nitriding, which can help reduce Ws valve guide wear and scuffing. Titanium nitride coatings are especially useful for high-heat applications, such as racing engines.
Choosing the best coating for your push rods depends on your engine’s specifics and intended use, making it important to consult with professionals to determine optimal coatings for your car’s make and model.
Upgrading your push rods can help you achieve optimal engine performance and power output. Understanding the various factors that affect performance push rods can help you determine the best push rods to meet your car’s performance demands.
When purchasing performance push rods, be sure to research and consult with trusted professionals to ensure the push rods you choose are compatible with your car’s make and model. By following this buyer’s guide and seeking expert advice, you can easily upgrade your push rods and dominate the road, track, or strip.
