Skunk2 Honda/Acura (H22A/F20B) Valve Spring Base Kit

Skunk2’s high-quality Spring Bases for Honda’s H-series VTEC engines are designed to allow any H-series VTEC cylinder head to accept Skunk2’s higher-performance, Pro Series Valve Springs and Titanium Retainers originally designed for B-series engines. Each Spring Base is manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to make sure the design is optimized for strength and longevity. Engineers then test and prove the design on the engine dyno. Once approved for manufacturing, engineers make sure to only use high-quality steel that’s been ultrasonically inspected and certified. After CNC machining, each Spring Base is then individually inspected to ensure proper dimensions and that it’s free from machining defects. 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. 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.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Upgrading your valve springs and retainers is the best way to help your car rev higher. If your are looking to increase the horsepower of your engine, your may have considered rebuilding the head. When rebuilding your engine's head, we recommend upgrading your valves, and springs. This will increase airflow and the RPM of your engine.

Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. For these reasons, top street cars and race cars worldwide rely on Skunk2 products. As part of Skunk2’s commitment to developing industry-leading products, we’ve remained actively involved in various forms of motorsports through technical partnerships, sponsorships, as well as with our own race vehicles for more than 15 years. We’ve gone on to secure a number of drag racing and road racing records and championships, including earning the title of the world’s first 10-second naturally aspirated Honda. Racing provides us with the data necessary to produce high-performance parts utilizing innovative designs, advanced metal alloys, cutting-edge manufacturing methods, and stringent quality-control measures. Driven by the desire to make things go faster, Skunk2’s staff is comprised of industry leaders, racers, and enthusiasts who are passionate about what they do and understand what other enthusiasts want. Our perspective is shaped by real-world racing experiences as well as by practical science, and that's precisely what makes Skunk2 products so good. Firmly grounded in our understanding of engineering, we make every effort to embrace advanced technology. Our goal is to make performance and technology accessible to other enthusiasts through innovative manufacturing techniques. Since 1994, we’ve released a number of industry-leading products, including the first cast aluminum, high-performance intake manifold, cutting-edge composite fuel rails, and valvetrain components made from premium materials. Skunk2 is acclaimed as being the first U.S.-based sport compact parts manufacturer to offer CNC-machined, adjustable cam gears in 1995 as well as billet camshafts in 1999. As a result of continually pushing our engine development capabilities in the racing world, we’ve discovered a number of exciting “power secrets” that are incorporated into every Skunk2 product. Today we continue our tradition of creating leading-edge products through a state-of-the-art engineering and R&D department as well as through extensive engine development and testing both on the race track and the street.
