Skunk2's industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2's already popular Pro Series Titanium Retainers, Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction. Alpha Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that's been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Finally, each retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road, including 11,000 rpm drag racing engines and 17,000 rpm superbikes. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support.

More than a decade ago, Skunk2s engineers revolutionized Honda performance by creating the first-ever, high-flow, cast aluminum intake manifold. Skunk2's Pro Series Intake Manifold for Honda's H-series features a larger plenum and oversized runners when compared to the OEM version for maximum horsepower and torque gains. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was designed for the 'street enthusiast' who wants more power but doesn't want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains. Skunk2's cast-aluminum Pro Series Intake Manifolds for Honda's H-series engines are a direct-fit replacement for all H-series engines and are compatible with all factory sensors. Pro Series Intake Manifolds offer horsepower and torque gains greater than competitors' manifolds but without compromising mid-range power output. The design incorporates specially tapered runners as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined to best match the cylinder head's ports. Skunk2's Pro Series Intake Manifold's shape and design also increases wave scavenging effects at the engine's ideal operating range, which allow for a broad increase in usable power. Skunk2 is a familiar name in the intake manifold business, with more than 10 years of experience designing, testing, and building them. Similar to OEM manifolds, Skunk2's Pro Series Intake Manifolds are shell-molded from 356-aluminum, CNC-machined for superior strength, a precise fit, and a high-quality finish, and vacuum-tested for quality.

• Ideal For Turbocharged And Naturally Aspirated Applications

Alpha Series Rods are forged from select 4340 chromoly steel and feature an H-beam design, resulting in the ultimate strength-to-weight ratio. 4340 chromoly is one of the strongest materials available, however, not all 4340 chromoly is the same. As such, Skunk2 relies on extensive material testing and works closely with its foundry to produce high-quality rods at an affordable price. Comprehensive heat-treating, tempering, and shot-peening processes together ensure that each Alpha Series Rod remains consistent and strong. Finally, each rod is magna-fluxed to ensure integrity and that each process has been completed thoroughly and according to Skunk2's rigid specifications. Skunk2's engineers spent nearly three years developing and testing its H-beam rod design. The results are one of the strongest beam configurations available, capable of handling more than 900 hp. Engineers made use of FEA (Finite Element Analysis) to determine high-stress points and implemented features to reduce wear and increase strength. Skunk2's straight design distributes stress across a larger area when compared to tapered rods, providing additional support where necessary. Alpha Series Rods are manufactured from two-piece forgings, resulting in optimal grain orientation along the rod cap for increased strength. By orienting the metal's grain in the direction of stress along the rod cap, perpendicular to the stress exerted along the beam, strength is significantly increased. Skunk2's two-piece forgings provide a precision-tight fit between the rod's cap and its beam without resorting to the brittle materials required by other processes. Alpha Series Rods also feature dual oil passages at their pin ends, providing additional lubrication and cooling, which leads to an even stronger, more durable rod. Unlike other designs, Skunk2's carefully positioned, offset oil passages help deliver lubrication around the entire wrist pin, during each phase of the engine cycle.

By orienting the metal's grain in the direction of stress along the rod cap, perpendicular to the stress exerted along the beam, strength is significantly increased. Skunk2's two-piece forgings provide a precision-tight fit between the rod's cap and its beam without resorting to the brittle materials required by other processes. Alpha Series Rods also feature dual oil passages at their pin ends, providing additional lubrication and cooling, which leads to an even stronger, more durable rod. Unlike other designs, Skunk2's carefully positioned, offset oil passages help deliver lubrication around the entire wrist pin, during each phase of the engine cycle.

Alpha Series Rods are forged from select 4340 chromoly steel and feature an H-beam design, resulting in the ultimate strength-to-weight ratio. 4340 chromoly is one of the strongest materials available, however, not all 4340 chromoly is the same. As such, Skunk2 relies on extensive material testing and works closely with its foundry to produce high-quality rods at an affordable price. Comprehensive heat-treating, tempering, and shot-peening processes together ensure that each Alpha Series Rod remains consistent and strong. Finally, each rod is magna-fluxed to ensure integrity and that each process has been completed thoroughly and according to Skunk2's rigid specifications. Skunk2's engineers spent nearly three years developing and testing its H-beam rod design. The results are one of the strongest beam configurations available, capable of handling more than 900 hp. Engineers made use of FEA (Finite Element Analysis) to determine high-stress points and implemented features to reduce wear and increase strength.
