Street Proven Fab now offers American made and affordable 8.8 bolt kits for most LS applications. This kit is compatible with all gen 3 & gen 4 LS engines. SPF water pump bolts are zinc-plated steel bolts that resist corrosion in wet environments. The tensile strength of these bolts are 110,000 psi and meet ISO 4014, DIN 931 standards. The thermostat bolts are black-phosphate 10.9 grade bolts that are corrosion resistant, have a tensile strength of 150,000 psi and meet ISO 898-1 standards. These Class 10.9 steel bolts are made for high-stress applications. They are at least 25% stronger than medium-strength steel bolts. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.
KIT INCLUDES:
6X M8 1.25 80mm Bolts (Class 8.8 Steel Hex Head Bolts)
2x M6 1.00 20mm Bolts (Black-Phosphate 10.9 Bolts)

WARNING - This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information go to www.P65Warnings.ca.gov
ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.
STEEL (steel bolts): Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steels as well.
