Hawks Motorsports is pleased to offer our clients the following 434-3202 LS1/LS6/LS2 Stainless Steel Polished 12-Point Water Pump & Thermostat Housing Bolt Kit, ARP. This ARP fastener kit is designed for applicable GM Gen III and Gen IV LS-series engines and includes polished stainless steel 12-point bolts for the water pump along with the thermostat housing bolts.

If you're building an LS and you've already spent the time cleaning up the engine, painting or detailing the accessories, and getting the engine bay looking right, it makes sense to finish the job with hardware that looks the part. These polished stainless ARP bolts add that clean, high-performance look around the water pump while giving a fresh engine build or restoration a much more finished appearance than a collection of rusty or mismatched factory fasteners.

The 434-3202 kit features 12-point heads, polished stainless steel construction, and includes the thermostat housing bolts. ARP offers this application in both polished stainless steel and black oxide finishes, as well as hex and 12-point configurations. The compact 12-point head can be useful where access around LS accessory components is limited.

ARP identifies 434-3202 for Chevrolet Gen III and Gen IV LS-series applications. Current application information includes LS1 and LS2, while other current application references list additional LS engines and vehicle applications. Because LS water pump and thermostat configurations can vary between engines and applications, verify the exact engine and configuration before ordering.
