INTRODUCING: SMOKIN’ SS – Part 1
If you’ve ever built a car from scratch, then you know that getting the basic body and chassis together is not the tough part. What’s tough are all the details that eat up hours, days and weeks, but without this attention to detail, the project would suffer.
RUGGED LUXURY
Cars and trucks are all about utilitarianism. Although vehicles have become status symbols, at the core, it’s all about getting people or things from one place to another. Through the years, Ford Motor Company has solidified its place in the annals of automotive history with its incredible lineup of consumer and commercial trucks. As the nameplate has been expanded and new options made available, Ford’s famed F-Series truly offers something for everyone.

When you’re chasing horsepower, every ounce of wasted motion is power left on the table. That’s why the Super-Street GM LS Aluminum Roller Rockers are worth a hard look. Proform went back to the drawing board and rebuilt their rocker lineup from the ground up—stronger, smoother, and better-looking than ever.
These beauties are machined from lightweight aluminum, anodized in that unmistakable deep blue, and laser-etched with the Proform “P” and 1.7 ratio. But the real magic is inside: full cage bearing trunnions keep things planted at high RPM, while steel roller tips slice friction like a hot knife through 10W-30. The result? More efficiency, more valve lift, and more of that glorious LS top-end pull.
Designed for Gen III LS1/LS6 (1997–2004) and Gen IV LS2/LS4 (2005–present) V8 engines, these self-aligning rockers are a straight bolt-on with the included M8 hardware and pedestals. They’ll even clear valve springs up to 1.400 inches in diameter, giving you room to get rowdy with your cam choice later.
Why We Love Them: Race Tech for the Street
Because it’s not just about making power—it’s about making power reliably. These rockers reduce friction, sharpen valvetrain response, and look good doing it. They’re engineered to handle the abuse of big cams and high RPM, yet still right at home in a street-driven LS. In short: race-bred tech without the “only on Sundays” attitude.

- 1.7 Ratio for increased valve lift and flow
- Cage Bearing Trunnions = rock-solid stability
