MRC Racing Components Universal Timing Chain Guide for K20 K24 Engines

Protect your valvetrain with a proper timing chain guide. The MRC Racing Components Billet Timing Chain Guide for K20 and K24 engines is CNC machined from 6061-T6 billet aluminum and replaces the OEM lower timing chain guide. Factory plastic guides wear down over time and can break, leading to chain skip and potential valve-to-piston contact — a catastrophic and expensive failure. This billet guide eliminates that risk.

Billet Timing Chain Guide Features

• CNC Machined 6061-T6 Billet Aluminum — Precision-cut for exact fitment and long-term durability
• Replaces OEM Lower Chain Guide — Direct replacement for the factory plastic guide
• Prevents Timing Chain Skip — Maintains proper chain tension and alignment
• Eliminates Plastic Guide Failure — No more worrying about broken plastic guides causing engine damage
• Lightweight Construction — No weight penalty versus the factory part

Fitment / Applications

• Honda K20 engines
• Honda K24 engines
• All K-series engine applications (OEM and swap builds)

Notes

• Replaces the lower timing chain guide only
• Installation requires access to the timing cover area — recommended during engine build or timing chain service

Pro Tip: If you are building a K-series engine for any kind of performance use, replace the lower timing chain guide while you have the engine apart. The factory plastic guide is a known weak point, and the cost of a billet replacement is nothing compared to the cost of a dropped valve from a skipped chain. This is cheap insurance for your build.
