Sure Seal 1In Alum A/C Riser Fit Flat Base

The Sure Seal 1In Alum A/C Riser Fit Flat Base is an essential component for builders and tuners looking to optimize the clearance between their air cleaner and carburetor. This precision-engineered spacer is designed for enthusiasts running performance setups where standard clearances are insufficient for throttle linkages or high-rise intakes. By providing a full inch of vertical lift, it ensures that your air cleaner sits securely without interfering with critical engine components. Mechanics often buy these risers to solve fitment issues during custom engine builds or complex restoration projects.

Constructed from high-strength aluminum, this riser features a 5-1/8 inch flange diameter that fits most standard four-barrel carburetors and throttle bodies. The natural aluminum finish provides a clean, professional appearance under the hood while resisting the thermal stresses of a high-performance engine bay. The integrated Sure Seal design is critical, as it utilizes a specialized lip to prevent unfiltered air from bypassing the cleaner element. These technical specifications ensure that your engine receives only clean air, protecting internal components from debris while maintaining a consistent vacuum seal.

This riser is specifically engineered for flat-base air cleaners, making it a versatile solution for a wide range of domestic and high-performance vehicles. It is particularly beneficial for those upgrading to HEI distributors or larger fuel lines that often conflict with the air cleaner housing. Installation is straightforward, requiring no modifications to the carburetor flange itself, allowing for a quick and effective performance adjustment. Reviewing your hood clearance is recommended before you buy this component to ensure the additional one-inch height fits within your vehicle's profile.
