New style units with copper bushings and rounded brackets. Put an end to the hassle and welding required to install Rotax exhaust ball joints with our new Ball Joint Conversion Kit. This simple bolt-on kit installs in minutes and eliminates all custom placement and welding of standard Rotax exhaust hooks. A matching pair of stainless steel half brackets surround the existing exhaust pipe and are secured with AN fasteners and hi-heat lock nuts. AN3 bolts and SS springs tension the brackets to provide a firm yet flexible joint. Also eliminate the large diameter springs that can break and strike prop. Sold in kits per joint.

Q: How much do I torque the nuts down?

You need 2-3 threads showing on each bolt and that will set the correct spring tension.

Q: Can I use it on the Rotax 503 engine exhaust system? Or it is only suitable for the Rotax 912 engine?

Yes. This kit is designed for the two stroke engines. It will not work on the 9 series engines.

Q: Is this kit for one joint or is it for both joints?

This is for one joint.
