Overview

The DSS Racing 4857-3710 is a set of forged pistons designed for Ford 4.6L Modular engines. These FX Series pistons feature a -13cc dish top and are designed to accommodate various cylinder head configurations, including 2V, TW, 3V, and 4V Modular Multi-notch heads. Constructed from a 2618 alloy, they are built for high-performance applications.

Key specifications include a 3.710-inch bore size, a 1.210-inch compression height, and a 0.866-inch pin diameter. The pistons also feature larger, deeper CNC valve reliefs suitable for more aggressive camshafts and cylinder heads, as well as horizontal gas ports to enhance ring seal.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.
