Magnum Roller Rocker Arms: Chevy; 3/8" Stud, 1.52 Ratio
These Magnum Roller Rocker Arms for Chevy V8 265-400 and V6 200-262 applications are the ultimate street rocker. With a 3/8" stud diameter and 1.52 ratio, they are designed for serious performance enthusiasts. All Magnum Roller Rocker Arms are constructed from 8620 chromemoly steel, which is a superior material that will not flex and assures maximum lift. Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, Magnum Roller Rockers are perfect for performance applications with less than 350 lbs. open spring pressure. Don't accept inferior products or cheap knock-offs, look for the COMP Cams® logo stamped into the underside of every Magnum Rocker.

Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
