Features & Product Details
AMS Performance has designed the 4B11 cam cap to replace the OEM unit that are prone to cracking. And the factory cam cap is not sold separately from the head itself so it can be a much costly repair.
AMS now offers the 4B11 cam cap as a great solution so customers aren’t stuck with purchasing an entire cylinder head from the factory. These are crafted from billet aluminum which is CNC machined, and etched with the famous AMS logo, and is designed using the Solidworks CAD software.
Please note that align honing of any cam cap to your existing cylinder head by a professional machine shop is necessary to ensure exact tolerances. Because the measurements between one cylinder head to another may vary, this cam cap cannot be just replaced and bolted into place, or engine damage will occur.
