Hawks Motorsports is pleased to offer our clients the 134-2201 Gen III/IV LS1 LS2 LS3 LS6 LSX Pressure Plate Bolt Kit from ARP. These High Performance pressure plate bolts are designed for Chevrolet LS-series clutch applications using 10-inch and 11-inch clutches. The kit features heat-treated 8740 chromoly construction, a black oxide finish, hex heads, and hardened washers.

When you're putting an LS-powered car together, clutch hardware is one of those little details that deserves the same attention as the big stuff. These ARP pressure plate bolts give your clutch assembly serious performance-grade hardware instead of relying on questionable old fasteners. With the right grip length, high-strength chromoly construction, and a clean black oxide finish, they're a solid choice for a street-driven build, swap, or performance LS setup.

ARP specifically designs its pressure plate bolts around the application to provide the appropriate grip length. The 134-2201 uses an M10 x 1.50 thread, a large-diameter low-profile hex head, and is nominally rated at 180,000 psi tensile strength. The kit is supplied as a set of six bolts with hardened washers.

• ARP lists 134-2203 as the pressure plate bolt kit for LS-series applications using a 12-inch clutch.
• Verify the clutch diameter and pressure plate configuration before ordering.
• The bolts use an M10 x 1.50 metric thread.
• This is a pressure plate-to-flywheel fastener kit; it is not a flywheel-to-crankshaft bolt kit.
• The kit contains six bolts and hardened washers.
• Do not substitute flywheel bolts for pressure plate bolts or vice versa.
• LS7-specific clutch hardware should be verified against the actual pressure plate and flywheel configuration before ordering.

INSTALLATION NOTES

• Follow the current ARP installation instructions and recommended torque specifications.
• Clean the pressure plate and flywheel fastener threads before assembly.
• Verify that the bolts have the correct thread engagement and grip length for the specific clutch assembly.
• Apply the appropriate ARP-recommended lubricant where specified.
• Tighten the pressure plate fasteners gradually and evenly using the manufacturer's recommended sequence.
• Rotate the assembly during installation as necessary to progressively seat the pressure plate evenly.
• Verify that the clutch disc remains properly centered during pressure plate installation.
• Always follow the clutch and pressure plate manufacturer's assembly instructions in addition to ARP's fastener recommendations.
