What we do?
Using a custom biuilt pinching tool supplied to us by Adam Drake, we take your worn out piston and sleve; with little to no compression, resize the sleeve to restore the compression to expected levels. Unlike other pinching services, there is no need to break-in your piston and sleeve after this process is completed. We recommend idling for one tank and then proceed directly to the track with a race tune.
What we need?
Simply mail us your old piston & sleeve. It's best to leave the con-rod attached to prevent wear and tear on the retaining clip. Package should be mailed to the following address:
Address will be supplied upon receipt of order.
Note: We only offer pinching service for .21 (3.5 CC) Engines at this time.
