Good To Know

Q: Will this fit my 2016 GTX S 1503? A: It is listed for that exact model year and 1503 platform, but confirming by serial number is advised before ordering. Q: Do I need to replace the chain at the same time? A: Many technicians replace the chain and related tensioner components together during a timing service.

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