ARP 203-4302 Toyota Head Stud Kit - 2ZZGE 1.8L

The ARP 203-4302 head stud kit is engineered specifically for the Toyota 1.8L 2ZZ-GE engine, providing superior cylinder head clamping force and improved head gasket sealing for high-performance and racing applications. When you increase power beyond factory specifications, cylinder heads can separate from the block, stretching factory bolts and causing engine failure. This premium head stud kit prevents head lift and maintains proper gasket compression even under extreme conditions.

Key Features:

• Manufactured from ARP2000 material with 220,000 PSI tensile strength
• Heat-treated prior to precision thread rolling for maximum strength
• 12-point nuts with parallel ground washers for even load distribution
• Black oxide finish for corrosion resistance
• Reusable design unlike factory head bolts
• Complete kit includes 10 studs, 10 washers, 10 nuts, moly assembly lube, and instruction sheet

ARP studs offer superior clamping accuracy compared to bolts because they don't twist during installation, providing more accurate torque readings and reducing stress on aluminum block threads. This results in increased block life and reliable performance in racing, turbo, and supercharged applications. Torque specification: 70 ft-lbs with ARP lube or 80 ft-lbs with 30-weight oil.
