1 7/8" Primaries
3" Collector
Includes: headers w/ graphite gaskets
optional MLS gaskets
optional header to head, bolt kit

Vehicle Applications:

1960-1987 C10 Trucks
1960-1987 K10 Trucks
(1960-1966 C10 Trucks require slider engine mounts to clear the front crossmember)

Note: If using a larger 4L80E, older Turbo 350/400 or Manual transmission the bellhousing ears may need to be trimmed for proper clearance

Note: Headers do not hang below the frame and offer ground clearance with air ride suspension and lowered suspension. Customers have installed this product on Choppin Block, Roadster Shop(with Pro spindles), Porterbuilt, and other front drop members with air ride and coil over suspension.

Note: Can fit 4wd applications with proper engine position and custom exhaust work. Having lifted suspension is a plus for driveline clearance.

Note: This product with off road x pipe kit will need a modified or aftermarket crossmember for fitment on installation. This kit will work with Suspension Engineering transmission crossmember with required shims (4L60 will need 3 shims).
