If you're planning any upgrades to your 4.6/5.4L 2 V or 4 V modular engine (such as performance improvement heads), then it's a good time to update your timing chain. Since they're interference engines, timing component wear can ruin your day. That's why Trick Flow® has engineered these replacement timing chains to keep your engine running smoothly.
