This kit is engineered specifically for Chevrolet GM Gen III and Gen IV LS-series 4.8L, 5.3L, 6.0L and 6.2L engines and replaces factory hardware with a tougher fastener designed to resist stretching, corrosion and fatigue under heavy loads. The package includes the hardened bolt, a parallel hardened washer, a dedicated socket and assembly lubricant so you have everything needed for a proper install.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this bolt improve reliability on high-torque LS engines?\u003c\/h3\u003e\n\u003cp\u003eThe bolt is manufactured from 8740 chrome-moly steel with a corrosion-resistant black oxide finish and a 200,000 psi tensile rating to resist elongation and shear. That strength reduces the chance of thread pull-out or bolt stretch when running increased torque, forced-induction, or high-rpm applications. The hardened washer and precise fit help maintain clamping force and crank timing stability under repeated thermal cycles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e8740 chrome plated steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish to resist corrosion and galling\u003c\/li\u003e\n  \u003cli\u003eHardened parallel washer preserves clamp surface against deformation\u003c\/li\u003e\n  \u003cli\u003e200,000 psi rating for superior holding power\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes installation straightforward for DIYers and shops?\u003c\/h3\u003e\n\u003cp\u003eThis kit includes a dedicated 12-point high-head socket and assembly lubricant so you don't need to source specialty tools or compounds. The 12-point head provides better socket engagement and reduces round-off risk, while the lubricant eases torque accuracy and prevents thread damage. A clear installation manual guides torque specs and sequence to help produce consistent results.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncluded 12-point socket fits the bolt head for secure turning\u003c\/li\u003e\n  \u003cli\u003eAssembly lubricant supplied to ensure correct torque readings\u003c\/li\u003e\n  \u003cli\u003eComprehensive instructions reduce guesswork during fitment\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct-fit replacement for GM Gen III\/IV LS engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this kit fit my specific LS engine and balancer type?\u003c\/h3\u003e\n\u003cp\u003eThe kit is designed as a direct-fit solution for GM Gen III and Gen IV LS-series 4.8L, 5.3L, 6.0L and 6.2L engines and their common harmonic balancers. It matches factory geometry and thread engagement so you won't need modifications to the crank or balancer. For unusual aftermarket balancers, double-check thread pitch and counterbore dimensions before installing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConfirmed fit for Chevrolet LS 4.8L, 5.3L, 6.0L, 6.2L factory-style balancers\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for GM Gen III\/IV balancer hardware\u003c\/li\u003e\n  \u003cli\u003eVerify aftermarket balancer compatibility if non-factory dimensions differ\u003c\/li\u003e\n  \u003cli\u003eIncludes hardened washer to match OEM clamp geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the construction resist corrosion and long-term wear?\u003c\/h3\u003e\n\u003cp\u003eThe bolt combines a high-strength steel core with chrome plating and a black oxide corrosion layer to provide both mechanical durability and environmental protection. Chrome plating offers an initial barrier against oxidation while the black oxide finish reduces surface friction and helps prevent galling where the bolt contacts the washer or socket. Together these treatments extend service life in wet or salty conditions common to road use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eChrome plating for initial corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces friction and resists surface rust\u003c\/li\u003e\n  \u003cli\u003eHardened materials prevent wear at contact points\u003c\/li\u003e\n  \u003cli\u003eDesigned for repeated removal and reinstallation without rapid degradation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This Xotic Performance CP236 kit is aimed at professional mechanics, performance shops and experienced DIY enthusiasts who work on Chevrolet LS engines and want a stronger, more reliable balancer fastening solution than stock bolts. It's particularly useful for builders upgrading torque capacity, installing aftermarket balancers or restoring older engines where original hardware shows wear.
