Complete Full Gasket Kit for HONDA CRF450R / CRF450RX (2017-2018) – OEM-Grade Sealing for Unmatched Engine Reliability

Protect your Honda CRF450R or CRF450RX’s high-performance engine from costly leaks, blowouts, and premature wear with this Complete Full Gasket Kit, engineered exclusively for 2017-2018 models. Built to handle the extreme heat, vibration, and pressure of motocross, supercross, and aggressive trail riding, this kit delivers factory-grade durability to seal critical components, preserve compression, and keep your engine running strong. Whether you’re rebuilding, maintaining, or fixing pesky leaks, this all-in-one set has every gasket you need—no more hunting for mismatched parts or settling for subpar replacements.

What’s Inside the Kit?

This comprehensive set includes every essential gasket for your CRF450R/RX’s engine, designed to fit like factory originals and deliver long-lasting, airtight seals. Key components feature:

• Cylinder Head Gasket: Multi-layer steel (MLS) or precision composite construction engineered to withstand extreme combustion pressures (up to 135+ PSI) and scorching temps (exceeding 260°C/500°F). Prevents coolant/oil leaks and maintains optimal compression for peak horsepower.
• Crankcase/Engine Block Gasket: Heavy-duty rubber-coated metal or heat-resistant composite design seals the crankcase to the block, stopping oil seepage and protecting internal bearings, gears, and crankshaft seals from dirt and debris.
• Oil Pan Gasket: Reinforced with high-temp fibers to block oil leaks at the engine’s base, keeping your lubrication system clean and reducing sludge buildup—critical for off-road rides where grit and grime are constant threats.
• Valve Cover Gasket: High-performance silicone or nitrile rubber blend blocks oil leaks around the valve cover, preserving engine cleanliness and minimizing carbon buildup on spark plugs (a common culprit in power loss).
• Timing Cover Gasket: Durable, sealant-backed material protects timing chains/guides from dirt, mud, and moisture—key for maintaining precise valve timing under high-stress track or trail conditions.
• Exhaust Manifold Gasket (if applicable): Aluminum or stainless steel-reinforced to resist corrosion and extreme exhaust temps, preventing blowouts and keeping exhaust flow (and power) optimized.

Why This Kit Outperforms the Competition

• CRF450R/RX-Specific Engineering: Tailored to match Honda’s legendary 450cc engine design—materials and dimensions tested to handle the vibrations, heat, and pressure of motocross and off-road riding (no generic “fits most” shortcuts here).
• OEM-Quality Durability: Matches or exceeds factory specs for compression resistance, heat tolerance, and chemical resistance (coolants, oils, and detergents)—so you get factory-level reliability, not budget compromises.
• Complete Coverage, Zero Hassle: No need to buy 6+ individual gaskets separately. This single kit covers every major sealing point on your CRF450R/RX, saving you time, hassle, and money at checkout.
• Cost-Saving Value: Save 40-60% vs. purchasing gaskets individually from dealers or aftermarket shops—without skimping on quality.
• Leak Prevention, Power Preservation: Restores airtight/liquid-tight seals to critical areas, protecting against costly damage like blown head gaskets, oil starvation, or overheating during intense rides.

Perfect For:

• Routine maintenance (every 1-2 years or 50+ hours of riding).
• Engine rebuilds, overhauls, or after replacing components (e.g., pistons, valves, or camshafts).
• DIY riders, mechanics, and trackside tuners looking to simplify parts sourcing and reduce labor costs.
• Enthusiasts aiming to extend engine life and keep their CRF450R/RX’s legendary Honda power and agility alive season after season.

Pro Installation Tips

• Clean Mating Surfaces: Use a gasket scraper and brake cleaner to remove all old gasket material, grease, and debris—any residue guarantees leaks.
• Follow Torque Specs: Refer to your Honda service manual for exact torque settings (critical for avoiding warped gaskets or damaged threads).
• Sealant Sparingly: Use a high-temp, non-hardening gasket sealant (e.g., copper-based) only if recommended for porous materials (check your manual—some gaskets are pre-coated).
• New to Builds? If you’re unsure, consider professional installation—we’re happy to recommend trusted mechanics in your area to protect your investment.
