Overview
Show original supplier description
Part #: CSIT-LS
Made In USA. Builders have found an issue when assembling the GM LS engines timing sets. Improper installation of the camshaft sprockets or phasers can damage or push the locating pin back into the camshaft during installation. As a result Melling has released the CSIT-LS installation tool which is designed to aid in the installation of both the camshaft and the camshaft sprocket or phaser. The CSIT-LS can be used with both single bolt and 3-bolt cams. The CSIT-LS installation tool is made from alloyed tool steel and heat treated for durability.
Features:
- Precise Gear Alignment - Designed specifically for LS engines to ensure accurate and damage-free camshaft gear installation
- Time-Saving Design - Streamlines the installation process, reducing the risk of errors and speeding up assembly
- Heavy-Duty Construction - Built from durable materials to withstand repeated use in professional or DIY engine builds
- Engine-Specific Fitment - Tailored to match LS camshaft gear profiles for a secure, slip-free installation every time
