Custom Pistons

Custom piston manufacturing is, and always will remain, the primary function at ARIAS. We have the technical know-how, flexibility, resources and passion to create a product tailored to your special requirements.

ARIAS also stocks piston kits of popular combinations on the shelf, ready for immediate delivery. If your combo cannot be found in our stocking piston listings, contact us about customs. We won’t try to sell you a kit that is "close enough". Instead, we’ll extract critical information about your power plant and deliver a functional set of pistons to suit your needs.

ARIAS PISTONS has manufactured custom pistons since its beginnings. After-market pistons, for most American-made vehicles, are manufactured in a regular basis per customer’s specifications.
