Description
xOverview
Designed for GM Gen III and IV LS engines, including the popular 4.8L, 5.3L, 6.0L, and 6.2L variants, the Hardened Harmonic Balancer Bolt from Xotic Performance combines rugged reliability with a clean installation path. This kit is engineered to integrate with your engine's balancing system, offering a purpose-built fit that aligns with factory spacing and lubrication guidelines. The bolt's 8740 chrome-plated steel body and a corrosion-resistant black oxide coating are chosen to endure the heat, moisture, and road grime typical of daily driving and performance use.
At the core is a high-strength design rated to approximately 200,000 psi of holding power, which helps maintain precise alignment at higher RPMs and under load. While no single part guarantees a specific outcome, the combination of the bolt, washer, and mounting hardware is intended to support stable engine rotation and reduce the chance of loosening under vibration. The result may translate into smoother operation and more consistent timing across a wide range of driving conditions.
What makes this kit special
In addition to the bolt itself, the kit includes everything needed to complete the installation with confidence. The rugged 12-point high-head design simplifies engagement with the harmonic balancer, and the accompanying socket ensures a proper tool is always on hand. A dedicated assembly lubricant is provided to ensure proper lubrication during installation, while a hardened parallel washer helps seat the bolt evenly, contributing to a tidy, repeatable setup that many DIY enthusiasts value.
