Good To Know

Q: Does this chain need to be replaced with the tensioner? A: Timing chains are often serviced together with the tensioner and guides since wear on one accelerates wear on the others. Inspect all related components during installation.

Q: Will this fit my exact GTX STD 155? A: It is listed for the 2017-2018 GTX STD 155 1503, but confirming your serial number and engine code before ordering is recommended.

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