What engine sizes do these pistons fit?

These Mahle OE pistons are designed for 229 cubic inch 3.8L and 305 cubic inch 5.0L engines. They are sized .030 inches larger than stock.

Are the piston rings included with this set?

Yes, this set comes with the pistons ready for installation, including the mounted piston rings, piston pins, and clips.

What does 'expansion controlled design' mean for these pistons?

An expansion-controlled design helps the piston maintain tight clearances within the cylinder bore as it heats up. This reduces engine noise, wear, and emissions, while also improving oil control.

Product Details

If you're rebuilding the engine in your classic GM car or truck from the late 70s or 80s, a fresh set of pistons is key to getting it running right. This Mahle OE cast piston set is designed for engines like the 229 cubic inch 3.8L and the 305 cubic inch 5.0L, and it's sized .030 inches larger than stock to help account for cylinder wear.

Mahle is a major OE supplier, so these pistons come with the same features you'd find from the factory. They have compensated ring grooves to ensure your piston rings seal properly and control oil, and their expansion-controlled design helps reduce engine noise and wear by maintaining tight clearances. This set includes eight pistons, pins, and clips, so they're ready to go right into your build, saving you a step during assembly.

This set fits a wide range of vehicles from Buick, Chevrolet, and GMC, including popular models like the Chevrolet C10, Camaro, and Monte Carlo, as well as the Buick Regal. Make sure to check the full fitment list to confirm it's the right choice for your specific application.
