Exhaust Valve Gasket Kit for Arctic Cat F6/F7/F8/F1000 EFI/Sno-Pro (2003-2013)

Material Composition High-temperature aramid fiber reinforced composite with nitrile rubber binder, formulated for harsh 2-stroke snowmobile exhaust operating conditions Gasket Thickness 0.060 inch (1.52mm) uniform profile across all gasket faces to maintain even clamp load without distorting aluminum exhaust valve housing surfaces Included Kit Quantity 8 precision die-cut exhaust valve gaskets, matched to cylinder port dimensions for all listed F6, F7, F8, and F1000 EFI/Sno-Pro model variants Continuous Heat Resistance Rating 1200°F continuous exhaust temperature tolerance, with a 1400°F intermittent heat rating to support wide-open-throttle, high-RPM trail and mountain riding OEM Cross-Reference Compatibility Direct drop-in replacement for Arctic Cat factory part numbers 3006-527, 3007-225, and 0930-047, requiring no cutting, trimming, or modification for proper fit Recommended Installation Torque 8–10 ft-lbs of torque on exhaust valve cover fasteners, applied in an alternating crisscross tightening pattern to prevent uneven gasket compression and air leaks Seal Pressure Rating Maintains a positive, leak-free seal up to 55 PSI of exhaust backpressure, preventing leak-related horsepower loss, elevated exhaust noise, and accelerated exhaust valve carbon fouling Chemical Resistance Impervious to EFI fuel residues, exhaust system condensate, and 2-stroke injection oil breakdown to prevent premature gasket swelling, cracking, or degradation Compression Set Rating Less than 10% compression set after 22 hours of sustained clamped load at 300°F, ensuring consistent seal performance across the full recommended service interval Recommended Service Replacement Interval Designed to match the factory 2000-mile exhaust valve service schedule, recommended for replacement during every routine exhaust valve cleaning or adjustment Cold Temperature Durability Rated for -40°F ambient operating conditions without brittling or cracking, suitable for extreme winter snowmobile use in arctic and alpine environments Port Alignment Tolerance +/- 0.005 inch die-cut alignment tolerance for exhaust port bolt holes, ensuring perfect alignment during installation without offset or overhang into exhaust flow paths
