Sprint Air Box Seal Ext Lip 2-5/8in - 2-7/8in

The SEALS-IT Sprint Air Box Seal with Extended Lip (2-5/8in – 2-7/8in) is a precision-engineered air intake closure system designed for sprint car racing and high-performance motorsports applications. This extended lip air box seal accommodates stack heights between 2.625 and 2.875 inches, making it compatible with a range of competitive engine configurations where air intake sealing is critical to performance consistency and compliance.

Constructed from a combination of aluminum and rubber materials, this seal delivers both structural rigidity and vibration dampening essential in high-RPM racing environments. The aluminum core provides durability under thermal cycling and pressure fluctuations typical in sprint car operation, while the rubber interface creates a consistent, repeatable seal against the air box carb stack interface. The extended lip design increases sealing surface area, reducing air leakage around high-velocity intake stacks—a critical factor in maintaining precise fuel metering and engine performance during competition.

Sprint car competitors and engine builders rely on SEALS-IT air box seals to maintain air intake integrity across multiple race events. The adjustable size range accommodates both stock and custom-built stacks, reducing the need for multiple seal inventory. Each unit is sold individually, allowing targeted replacement or system rebuilds without purchasing unnecessary extras.

Whether you're preparing for a full season or replacing a worn seal mid-season, this SEALS-IT product maintains the precision air intake closure your engine demands. Available at TacticalSurplusUSA for quick delivery to your shop or track.
