GPI Modified Lower Timing Gear for Gen V LT Engines - Wet Sump - GPI-1214
Engineered Timing Gear Upgrade for Aftermarket Cranks
The GPI-1214 Modified Lower Timing Gear is purpose-built for Gen V LT engines running aftermarket crankshafts in wet sump configurations. OEM timing gears feature a flat inner surface, which does not properly accommodate the radiused snout found on most aftermarket LT crankshafts. This mismatch can create unwanted pressure points, leading to timing gear cracking or total gear failure.
GPI resolves this with a precision-machined chamfered inner edge that perfectly matches the snout radius of performance crankshafts - ensuring correct fitment, proper load distribution, and long-term durability under high-RPM and high-stress operation.
Product Overview
This OEM-quality timing gear retains factory dimensional accuracy while providing the critical modifications required for aftermarket crank compatibility. Whether you're building a high-power LT1, LT4, L86, or other Gen V variant, this gear eliminates a known failure point and ensures the timing system operates exactly as intended.

FAQs
Why is the chamfered edge necessary?
Most aftermarket LT crankshafts have a radiused snout. The OEM timing gear's flat surface does not clear this radius, creating excessive stress that can lead to cracking. The chamfered edge eliminates this interference.
Will this work with both boosted and naturally aspirated builds?
Yes. Any build using an aftermarket crank - boosted, nitrous, or N/A - benefits from proper timing gear-to-crank snout fitment to avoid premature gear failure.
