Good To Know

Q: How many O-rings should I order? A: Each engine uses one O-ring per power valve, so check your valve count and order accordingly. Replacing both at once keeps sealing consistent across the exhaust system.

Q: Does this fit models other than the GTX 951? A: This O-ring is listed for the 951 engine platform in the GTX. Confirm your model and serial number match before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
