JM

I recently installed the Chevrolet Small Block Piston Kit by JE Pistons in my small-block engine. The performance boost has been incredible! The pistons fit perfectly, and the 4032 aluminum material holds up great under heat. The pin oiling system makes a noticeable difference in engine smoothness. Highly recommend for anyone looking to up their engine game.

I installed the Chevrolet Small Block Piston Kit in my 350 engine, and it really brought the power back. The forged design is top-notch, and the pistons fit with no issues. I love that they're made in the USA too. Great value for the price!
