Head Gasket, Rear Cylinder by Indian

Unrivaled Reliability: Polaris OEM Head Gaskets Part #5815469 – Available at buywitchdoctors.com

The head gasket is arguably the most stressed seal in your entire V-Twin engine. It must maintain a perfect seal to contain high-pressure combustion, keep oil and coolant rigidly separated, and withstand extreme thermal expansion. A failing gasket means lost compression, overheating, and catastrophic engine damage.

When rebuilding or repairing your engine, never settle for generic parts. The Victory & Indian motorcycle head gasket from Witchdoctors.com is a genuine Polaris OEM component, designed, tested, and certified to meet the exact specifications of your powerful V-Twin. Invest in the factory seal that guarantees maximum compression and peak performance for the long haul.

Features & Benefits of Polaris OEM Head Gaskets

Polaris OEM head gaskets are engineered to surpass the demands of high-performance V-Twin engines like the Freedom 106 and the Thunder Stroke 111.

Why Choose OEM for Your Head Gasket Replacement?

A head gasket failure—often due to age, engine overheating, or material degradation—requires significant labor to repair. Given the complexity, choosing the right part is non-negotiable.

• Prevents Coolant/Oil Mixing: Maintains the critical separation of fluids, avoiding the "milky oil" contamination that destroys bearings and other internal components.
• Restores Compression: A perfect fire ring seal ensures maximum combustion efficiency, restoring lost horsepower and optimizing fuel economy.
• Avoids Overheating: Prevents combustion gases from leaking into the cooling system, which pressurizes and overheats your engine.
• Specific V-Twin Engineering: Aftermarket gaskets often use generic materials. OEM gaskets are made for the unique thermal signature and bolt pattern of the Freedom/Thunder Stroke engines.

Frequently Asked Questions (FAQs)

Q: How do I know if my Victory or Indian head gasket is leaking?

A: Common signs include white smoke with a sweet smell from the exhaust (burning coolant), overheating (pressure entering the cooling system), milky, foamy oil visible on the dipstick or under the oil fill cap, or unexplained coolant loss.

Q: Should I replace both gaskets on my V-Twin?

A: Yes. Since both the front and rear cylinders experience the same heat cycles and age simultaneously, if one gasket is failing, the other is likely to follow soon. Replacing both ensures uniform performance and saves on labor.

Q: Do I need new head bolts when replacing the gasket?

A: It is highly recommended to replace head bolts, as many modern engines use Torque-to-Yield (TTY) bolts designed to stretch permanently upon initial installation. Reusing TTY bolts will result in insufficient clamping force and lead to premature gasket failure. Always check your service manual.

Q: Can I use aftermarket head gasket sealant?

A: No. Polaris OEM head gaskets are designed to be installed dry (unless otherwise noted in the official shop manual). Chemical sealants can interfere with the MLS coating and compromise the engineered seal.
