Product Description
Genuine GM / IWIS Timing Chain & Sprocket Set – Gen V+ LT Engines
Fits 2019+ L84 L87 L8T L82 & 2022+ LT1 (8th VIN Digit = D, L, 7, F)
This Genuine GM / IWIS Timing Chain and Sprocket Set is the correct OEM-style replacement for 2019-newer Gen V+ LT engines including L84, L87, L8T, L82, and 2022-later LT1 applications. Designed to maintain factory reliability and proper cam phasing operation, this kit combines original GM sprockets and tensioner components with a premium German-made IWIS timing chain for superior strength, durability, and long service life.
This kit will NOT fit L83, L86, L8B, LT4, or earlier versions of LT1. For 2019–2020 truck/SUV models, you must verify that the 8th digit of the VIN is D, L, 7, or F, as GM used earlier L83/L86 configurations during those transition years. Installing the incorrect cam phaser sprocket on those engines will result in improper fitment.

- GM 12689342 Camshaft Phaser Sprocket
- GM 12630107 Timing Chain Tensioner
- GM 12713934 Crankshaft Sprocket Gear
