LS1 2 3 LSX ENG 4.8 5.3 5.7 6.0 6.2 HARMONIC BALANCER INSTALL & FLYWHEEL HOLDER

Harmonic Balancer Install & Flywheel Holder for LS1 LS2 LS3 LSX

This heavy-duty tool kit allows mechanics to safely install harmonic balancers and lock the flywheel on 4.8, 5.3, 5.7, 6.0, and 6.2 liter engines.

Overview

The harmonic balancer install & flywheel holder provides the necessary mechanical leverage to install pulleys and lock the crankshaft in place. This harmonic balancer install & flywheel holder is designed for mechanics working on high-performance engine platforms. Utilizing the harmonic balancer install & flywheel holder prevents the engine rotating assembly from spinning during critical torque procedures.

• Facilitating easy timing chain replacement or camshaft swaps.

Specs At A Glance

Good To Know

Q: Can the flywheel holder be used with automatic transmissions? A: Yes, it works on both manual flywheels and automatic flexplates by mounting in the starter position.

Q: Why is a dedicated installer tool necessary for the balancer? A: Using the balancer bolt to pull the balancer on can strip the threads inside the crankshaft snout, which this tool prevents.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
