Product Description

The ARP 234-6301 Pro-Series ARP2000® Rod Bolt set is engineered specifically for Chevrolet LS Gen III and IV engines (including 6.2 L LT1), excluding LS7 and LS9 variants. Designed with a cracked-cap style, these bolts are precision machined from ARP2000 alloy and undergo heat treatment to deliver up to 200,000 psi tensile strength - some listings indicate strengths reaching 220,000 psi. The E-style head and 12-point nut ensure tight engagement, while the Wave-Loc design enhances retention under high RPM and load conditions.

Ideal for performance and high-combustion applications, these bolts offer up to ten-times the fatigue strength of OEM fasteners. They require a simple 3/8" 12-point socket for installation, and stretch should be measured between 0.0065-0.0070 in using ARP lube, guided by a torque of approximately 40 ft-lb. Fitment is confirmed through 2009; 2025 compatibility is unverified at this time.
