About CrawfordSPEC Pistons

Every CrawfordSPEC piston features a unique design, engineered by and exclusive to Crawford Performance. We have worked side-by-side with JE Pistons to create a design with the following results:

• More manifold vacuum at idle, which makes for a tighter, healthier, more efficient engine
• Lower crankcase pressure
• All CrawfordSPEC pistons are sized for the OEM bore.

About CrawfordSPEC Rods

Every CrawfordSPEC rod is designed at a specific length, engineered by and exclusive to Crawford Performance. We have worked side-by-side with Pauter Rods to create a design with the following results:

• Longer than stock length not only increases strength but also increases the rod ratio which allows for smoother and more efficient power delivery
• Billet vs. Forged, made with the strongest steel available in the industry: 4340 chrome-moly

Fits: Subaru BRZ, Scion FR-S, and Toyota GT86 / 86 (2013–2021).

We recommend that certain parts be replaced new when installing a new long block into your vehicle. We have assembled a kit that includes each piece, down to break-in oil.

Send in yours, or choose New and the work is done on new OEM Subaru cylinder heads.

Send in yours, or choose New and the work is done on new OEM Subaru cylinder heads.

Send-in means you ship your cylinder heads to us after ordering — every send-in head is inspected first, before any work proceeds.
