Product Details

This is the COMP Cams GM38 255HR12 Xtreme Energy hydraulic roller camshaft, designed for naturally aspirated GM 3800 Series II and III 3.8L V6 engines. If you're looking to get more performance out of your engine, especially when paired with intake improvements, this camshaft is a solid choice. It's built to offer a noticeable bump in power and torque, making your vehicle feel more responsive.

This camshaft features a 201-degree intake and 205-degree exhaust duration at .050 inch lift, with a .380 lift on both intake and exhaust. The hydraulic roller design means it operates smoothly and efficiently, reducing friction compared to flat tappet designs. For this camshaft to perform correctly and safely, it's essential that you replace your stock valve springs with a set rated for this camshaft's lift and operating range. COMP Cams recommends specific spring kits to ensure proper valve control and prevent valve float at higher RPMs. This part is not CARB approved and cannot be shipped to California.

When installing this camshaft, remember that it's part of a system. While it offers improved performance on its own, you'll see the best results when combined with other intake modifications like a less restrictive air intake system or improved exhaust components. Always refer to the manufacturer's installation instructions for detailed guidance on replacing your camshaft and the necessary supporting components.
