Gasket Kit With Extra Thick Exhaust Gasket And Bolts
The GY6 Exhaust Bolt Nuts Gasket set is designed for engines from 50cc to 150cc and fits a range of scooters, ATVs, and go-karts. Its features include an extra thick gasket with a bolt-to-bolt spacing of 49mm and an inner port of 27mm, helping create a robust seal. The included exhaust studs measure 32mm in length with M6 threads, and the bronze gasket has an outside diameter of 30mm and an inner diameter of 27mm. This kit emphasizes dual-layer, double-sided construction for enhanced noise suppression and long-term durability in heat-heavy exhaust paths.
Ideal for riders who need a solid, all-in-one seal solution that reduces exhaust noise while maintaining a tight fit across multiple GY6 models.
GY6 150cc Exhaust Gasket Kit with Bolt Nuts
This kit targets a broad range of GY6 engines from 50cc to 150cc, including common platforms for ATVs, scooters, mopeds, and go-karts. It features a metal gasket with a 1.08-inch inner opening to accommodate various pipe interfaces while providing strong noise isolation. The graphite gasket material withstands high temperatures, reducing heat transfer and potential leakage. The included bolts and nuts are metal, providing durability and resistance to wear. This option emphasizes a quieter ride and solid structural integrity under typical engine heat conditions.
Consider this kit when you need a quieter exhaust interface and a robust graphite gasket that stands up to heat cycling.
GY6 Exhaust Kit with Nuts, Gasket, and Studs
Designed to fit GMB139 engines from 50cc to 150cc, this comprehensive kit includes two exhaust studs, two nuts, one exhaust gasket, two spring gaskets, two additional gaskets, and a premium metal gasket. The bolt spacing remains at 49mm with a 27mm inner port, and the set emphasizes a double-sided, double-layer design to minimize exhaust noise. It is ideal for riders seeking a complete replacement solution for worn-out hardware and gaskets, ensuring consistent torque retention and reliable sealing during operation.
Best for ongoing maintenance and those replacing multiple worn components in one go, without sacrificing seal quality.
HIAORS GY6 Exhaust Bolt And Gasket Kit
The HIAORS kit focuses on broad compatibility and durability for GY6 engines across many Chinese scooter and ATV models, including Taotao, Coolster, Xpro, SSR, Jonway, Hammerhead, and more. The set is built with sturdy metal components to ensure long-lasting performance and a secure fit that resists extrusion under high heat. It is well-suited for riders who demand reliable parts from a trusted brand, with attention to preventing leaks and maintaining consistent exhaust flow in daily use.

GY6 Exhaust Pipe Gaskets for 50cc QMB139 & 125cc/150cc Motors
These pipe gaskets are tailored for smaller GY6 engines, including QMB139 and the 125cc/150cc family. They provide a compact, precise fit with a simple inner diameter of 24mm and outer diameter of 30mm, with a gasket thickness of 5.4mm. While not a full kit, these gaskets play a critical role in the flange-to-pipe interface, helping seal the joint and reduce minor exhaust leaks on compatible models. They’re a practical option for users focusing on precise gasket sizing and straightforward replacements.
Best for precise, low-profile gasket needs on specific QMB139-based setups.
Buying Guide
- Engine compatibility: Ensure the gasket kit explicitly lists GY6 engines in the 50cc–150cc range and a GMB139 flange if applicable. This prevents mismatches that could cause leaks or fitment issues.
- Gasket material and construction: Graphite or double-layer gaskets often provide better heat resistance and sealing compared to simple rubber compounds. Consider double-sided or extra-thick gaskets for tougher exhaust paths.
- Bolt and stud hardware: Kits that include studs, nuts, and multiple bolts simplify installation. Confirm thread size (often M6) and length to avoid undersized fasteners that fail under vibration.
- Noise reduction: Some gaskets feature dampening or metal dampening interfaces to minimize exhaust sound. If you ride in noise-sensitive areas, this can be a meaningful benefit.
- Installation considerations: Check if the kit includes additional gaskets, springs, or extra pieces that aid sealing around the exhaust flange. A complete kit reduces the need for additional purchases.
- Durability and heat resistance: Look for gasket materials that withstand high exhaust temperatures and resist extrusion or deformation over time.
- Brand and warranty: Reputable brands often provide better fitment consistency and support. A warranty or return policy can be helpful if the part doesn’t fit perfectly.
- Maintenance strategy: If you ride frequently or in harsh conditions, consider stocking a couple of spare gaskets and studs for quick on-the-road maintenance.
In selecting a gasket kit for a 150cc GY6 setup, consider not only the gasket material but also the completeness of the kit. A kit that includes gaskets, bolts, studs, and nuts offers greater assurance against leaks and misalignment after installation. For riders prioritizing noise reduction, see options with sound-damping features. Always verify fitment against your specific model and engine type before purchasing to ensure optimal sealing, performance, and a quieter ride.
