RYANSTAR RACING Exhaust Manifold Clamp Repair Kit – Replaces 11518860 / 917-107 – Fits 4.8L-6.0L Engines

Overview

RYANSTAR RACING introduces an external exhaust manifold clamp repair kit designed to simplify maintenance and address exhaust leaks by sealing the joint between the manifold and the cylinder head. The approach emphasizes practicality, allowing you to tackle a leak without removing or disturbing the original studs, which can save time and reduce complexity during repairs.

This kit centers on a clamp that attaches directly to the cylinder head, forming a secure seal at the critical junction where bolts may fail. By engaging the clamp externally, you can address leaks caused by damaged or broken manifold bolts while keeping other components intact. The result is a straightforward, space-efficient solution for stubborn leaks that might otherwise require more invasive work.
