GM 6.2L LT1 Head Bolt Kit

The ARP 234-3710 GM 6.2L LT1 Head Bolt Kit is a Pro Series chromoly fastener set engineered for the GM GenV LT-series engine platform. Built to withstand the demanding loads of high-compression and forced-induction applications, this 12-point head bolt kit delivers the clamping consistency and tensile strength required for reliable cylinder head sealing in performance and modified engine builds.

The Pro Series designation indicates these bolts are manufactured from high-strength chromoly material with black oxide finish for corrosion resistance and thermal stability. The 12-point head geometry provides superior engagement with socket tools, reducing the risk of rounding during installation and torque verification—critical when working with tight engine bay tolerances. ARP fasteners are precision-manufactured to exacting standards, ensuring consistent preload across all cylinder head positions and maintaining clamping force through thermal cycling and sustained engine operation. This kit contains the complete complement of fasteners needed for a full LT-series cylinder head installation.

Serious engine builders, LS and LT platform enthusiasts, and shops performing cylinder head work on GM GenV engines rely on ARP Pro Series fasteners for repeatability and durability. Whether building a street performance engine, a competition platform, or restoring an engine to OEM specifications with upgraded components, proper head bolt selection directly impacts combustion seal integrity and long-term reliability. The 234-3710 is the fastener choice for builders who understand that marginal gains in clamp load consistency translate to measurable improvements in engine stability and longevity.
