Product Overview
This 70mm exhaust stud bolt is designed as a replacement cylinder exhaust pipe mounting stud for many 50cc, 70cc, 90cc, 110cc, 125cc, and 150cc Chinese horizontal engines used on ATVs, dirt bikes, pit bikes, go karts, 4-wheelers, and quads.
Installed on the cylinder exhaust port, this double-ended stud helps secure the exhaust pipe or exhaust manifold to the engine cylinder. A worn, broken, rusted, or missing exhaust stud may cause exhaust leaks, loose exhaust mounting, abnormal noise, or poor sealing at the exhaust connection.
Please compare the length, thread size, shape, and installation position with your original exhaust stud before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This 70mm exhaust stud bolt may fit many 50cc, 70cc, 90cc, 110cc, 125cc, and 150cc Chinese horizontal engines used on ATVs, dirt bikes, pit bikes, go karts, and quads. Fitment depends on the cylinder exhaust port thread size, stud length, and exhaust pipe mounting design rather than model year alone.
Do I need to match the OEM part number?
Matching the OEM part number is helpful, but for this type of exhaust stud bolt, the key details are the total length, thread size, and installation position. Please make sure your original exhaust stud is 70mm long and matches the same cylinder exhaust mounting style.
What models or situations does this part not fit?
This part may not fit vertical engines, non-Chinese engine platforms, engines using a different exhaust stud length, different thread size, or a different exhaust flange mounting design. It is not suitable if your cylinder exhaust port threads or exhaust pipe mounting holes do not match this stud.
What should I check before ordering?
Before ordering, check your engine type, cylinder exhaust port design, original stud length, thread size, exhaust flange hole spacing, and product photos. This product is a 70mm double-ended exhaust stud for Chinese horizontal engine exhaust pipe mounting.
