Aynaxcol Exhaust Manifold Gasket Spring Rebuild Kit for Polaris 600–800 — Graphene High‑Temp, 5 Springs

The Aynaxcol Exhaust Manifold Gasket Spring Rebuild Kit restores a tight, high-temperature seal for Polaris Ranger, Sportsman and RZR 600–800 models to reduce leaks and improve exhaust integrity.

This rebuild kit supplies the main pipe inlet/outlet gaskets, a dedicated exhaust manifold gasket and five tension springs made from high-temperature graphene material. It replaces Polaris part numbers 3610047 and 5811511 and fits a wide range of models including Sportsman 600 (2003–2006), Sportsman 700 (2002–2007), Sportsman 800 (2005–2013), RZR and Ranger 800 variants (2008–2011 and select 2010–2011 4x4 models). The components are engineered for airtight mating surfaces and sustained exposure to extreme exhaust temperatures.

How will this kit stop my exhaust leaks?

The gaskets form a pressure-tight seal at the junctions where the exhaust manifold meets the head and the main pipe, while the springs maintain clamping force through thermal cycles. Together they limit hot-gas escape and reduce gasket blowout.

• High-temperature graphene material resists 800–1000°C softening.
• Pair of main pipe gaskets for inlet and outlet mating surfaces.
• Exhaust manifold gasket contours to OEM flange shapes for improved sealing.
• Five springs provide consistent tension to prevent loosening under vibration.

Which Polaris models and part numbers does this kit replace?

This kit is specified as a replacement for multiple Polaris part numbers and covers several model years of Rangers, Sportsmans and RZRs. Verify compatibility with your vehicle’s year and model before ordering.

• Replaces part numbers 3610047 and 5811511.
• Sportsman 600: 2003–2006; Sportsman 700: 2002–2007 (including Touring and X2).
• Sportsman 800: 2005–2013.
• RZR and Ranger 800 series: select 2008–2011 and 2010–2011 4x4/RZR 4 models.

What are the material benefits and temperature limits?

Gasket faces use a graphene-enhanced formulation created to preserve sealing integrity under intense heat and repeated thermal cycling. The material improves durability and airtightness compared with standard composite gaskets.

• Graphene-reinforced material for improved strength and seal retention.
• Rated to withstand high temperatures between 800–1000°C.
• Extra spring count for sustained clamp force over time.
• Resistant to exhaust gas corrosion and common thermal degradation.

What’s included in the package and how hard is installation?

The kit comes with all core components you’ll need to rebuild the manifold connection. Installation requires basic mechanical tools and moderate experience with exhaust work; gaskets must be aligned and springs correctly tensioned for a reliable seal.

• 1 pair main pipe gaskets (inlet and outlet) and 1 exhaust manifold gasket.
• 5 exhaust springs to maintain proper tension.
• Direct bolt-on replacements—no machining required if mating surfaces are in good condition.
• Recommend inspecting flanges and studs; replace damaged hardware as needed.

Who is this for: This kit is intended for Polaris owners and mechanics rebuilding or repairing exhaust systems on Sportsman, Ranger and RZR 600–800 models who need a durable, high-temperature sealing solution. It’s suitable for routine maintenance, repairing leak-prone flanges, or restoring exhaust integrity after component removal. Check model year and part numbers to confirm fit before purchase.
