Ford 6 Pre Cross Flow Shaft Rockers
Introducing the Street Terra Shaft Rockers for Ford 6 Pre Cross Flow engines, the best value rocker arm on the market today. Engineered to meet or exceed the needs of performance street and sportsman race applications, these rockers offer superior performance and reliability.
Key Features:
- High-Quality Construction: Our vacuum die-cast arms are designed and engineered for optimum strength without the costs associated with billet CNC machining.
- Premium Hardware: The Street Terra series utilizes extreme duty hardware from our premium Platinum race series, ensuring a lifetime of trouble-free performance.
- Easy-Fit Kits: Our Easy-Fit (EF) kits are a cost-effective alternative to factory stamped steel rocker arms and can be installed in less than an hour without cylinder head removal and, in most cases, without machining.
- High Lift Ratios: A wide range of true ratios allows you to achieve high lift without relying solely on your camshaft, reducing the inertia on lifters and pushrods generated by aggressive ramp rates.
Performance Benefits:
- Versatile Applications: Popular for standard rebuilds where OEM equipment is worn or scarce, as well as mild street applications. Ideal as a replacement for factory stamped rockers that have seen decades of wear and tear.
- Enhanced Durability: Vacuum die-cast arms are built to withstand up to 450lbs* max open spring pressure.
- Efficient Operation: Oversize full-complement caged bearings designed for oscillating loads, paired with oversize precision ground trunnions to reduce friction.
- Improved Valve Lift: Various ratios available, catering to every camshaft grind. High ratios allow for additional lift on stock and aftermarket camshafts.
- Bolt-On Shaft Mount Design: Proven design mounts both inlet and exhaust to a common shaft, effectively increasing footprint and clamp load twofold without further cylinder head modification.
- Smooth and Quiet: Chrome moly steel hardened and ground roller tips of generous diameter, positively retained by internal circlip, prevent abrasion of valve tips and guides. This results in smoother, quieter operation, maintains lash, and reduces engine maintenance.
Additional Information:
- Includes Adaptor Plates: Ensuring seamless installation and compatibility with your engine setup.
- Pushrod & Lifter Kit Required: Requires YT 14101-12 pushrod & lifter kit for optimal performance.
- Pushrod Length Variations: Note that the 170ci/Narrow block may differ in pushrod length, requiring adjustments for proper fit.
