Overview

The Harddrive Twin Cam 88 Primary Outer Chain is a stock replacement cam chain designed for Twin Cam 88 motors. It is a heavy-duty option that serves as a direct replacement for OEM part number 25610-99. This chain is part of a kit that also includes long-life cam chain tensioners.

Regular inspection of the cam chain tensioners is recommended due to varying wear rates influenced by factors such as usage and oil change frequency, to prevent potential engine damage. A compatible cam chain guide is also available separately.

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.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
