SBC 12pt Short W/P Bolt Kit

The ARP 134-3203 SBC 12pt Short W/P Bolt Kit is designed for builders and performance enthusiasts who require enhanced reliability in small-block Chevy engine builds. This bolt kit specifically addresses the water pump mounting interface, which can be a weak point in high-performance applications. As boost levels increase or nitrous is introduced, factory fasteners may fail, leading to potential coolant loss.

Manufactured from ARP's proprietary alloy steel, these bolts feature a unique 12-point head design that helps distribute clamping load more evenly compared to traditional 6-point fasteners. This design reduces the risk of thread galling during installation. The short length ensures proper engagement without bottoming out in the block's threaded holes, distinguishing this kit from lower-quality alternatives.

Ideal for various SBC applications, this ARP kit is a valuable addition for those looking to enhance their engine's performance and reliability. Each bolt is individually wrapped and comes with ARP's assembly lube to ensure consistent preload and prevent cross-threading. This complete water pump bolt set is suitable for many SBC configurations, making it a versatile choice for engine builders.
