Collector Gasket Kit - 3in Aluminum

The Collector Gasket Kit - 3in Aluminum from PROFORM is a precision sealing component engineered for high-performance engine builds and custom automotive applications. Designed for builders and technicians who demand reliability in critical assembly areas, this gasket kit addresses the need for leak-free collector-to-manifold connections in both street and competition environments. The 3-inch aluminum construction makes it ideal for systems where thermal management and durability are non-negotiable, particularly in modified or race-spec powerplants where standard gasket materials fall short.

Constructed from aircraft-grade aluminum, the Collector Gasket Kit provides superior heat dissipation and maintains structural integrity under extreme temperature cycles. The 3-inch diameter specification ensures proper fitment on mid-to-large displacement engines and custom collector systems where bore alignment and compression ratings are critical. PROFORM's engineered gasket design eliminates common leak paths at the collector interface, reducing the risk of exhaust bypass and maintaining cylinder scavenging efficiency. The kit's compact footprint (5.6 x 1.6 x 6.6 inches) allows for straightforward installation without requiring extended downtime or complex manifold repositioning.

Technicians rebuilding forced-induction systems, carbureted high-performance engines, and fuel-injected racing platforms will find this gasket kit indispensable for maintaining exhaust integrity and preventing performance loss. The aluminum composition suits both street applications and track environments where vibration and thermal cycling demand materials that won't degrade or crack over extended use. Installation on most header or collector systems is straightforward, requiring only standard hand tools and proper torque sequencing to ensure even clamping pressure. At 0.61 lbs, the kit's lightweight design adds negligible mass while delivering the sealing performance expected in professional engine assembly work.
