Understanding Flat Top Pistons Flat top pistons are the most common piston design you’ll encounter, but the term can be misleading if taken too literally. When you hear “flat top...

In high-performance naturally aspirated engines, piston assembly weight (piston, pin, rings, and locks) is always a concern. While lighter often seems better, too light can cut the race...

  When designing pistons, it’s not just about making them thick or thin — it’s about finding the right balance for the application and the forging being used . The...

Relying on bolt torque alone can lead to inaccurate clamp loads, giving a false sense of security that the bolts are properly tightened. Here’s why: What is bolt torque? Bolt...

When it comes to building serious power, every component matters—but few play as critical a role as the piston. For Yamaha Banshee riders and racers pushing the limits of two-stroke...

Shelf Pistons Receive Performance Upgrade We’re proud to announce a rolling change to our high-moving shelf piston part numbers. These pistons are now being upgraded with Profiled...

Are your pistons all the same (symmetrical), right-handed, left-handed or a combination of both? On some cylinder head designs, the spark plug is not always opposite the intake manifold like a...

While our recommended bolt stretch and clamp loads have been working well for many years, we can’t ignore the fact that rods continue to be subjected to more demanding tensile loads as...

As load requirements have increased over the years, CP-Carrillo developed an improved 3/8 CARR fastener to meet the rigorous performance standards one expects from Carrillo connecting rods. This...
