Yella Terra Street Terra: A superior choice for your 302 Windsor or GT40 roller rockers. Engineered to exceed performance street, this is undoubtedly the best value roller rocker available for the GT40 heads.

Yella Terra Street Terra Windsor GT40 roller rockers are designed for optimal strength using vacuum die-cast manufacturing, without the high costs of billet CNC machining. These roller rockers for 302 Windsor and GT40 heads come equipped with the extreme duty hardware of our premium Platinum race series, ensuring enduring performance.

Our Yella Terra EasyFit (EF) kits are a cost-effective alternative to factory-stamped steel rocker arms. They can be installed in less than an hour, eliminating the need for cylinder head removal or extensive machining.

With a wide range of true ratios, Yella Terra GT40 roller rockers help achieve high lift without relying solely on your camshaft. This trend is gaining popularity among engine builders and racers, as it relieves the inertia on lifters and pushrods caused by aggressive ramp rates needed to create significant lift.

Ideal for standard rebuilds where OEM equipment is worn or scarce, as well as for mild street applications, our Ford AU GT40 head roller rockers and 302 Windsor roller rockers are your go-to choice for unmatched performance and reliability. Experience the Street Terra difference today.
