Fits 2003-2023 Dodge/Ram 2500 and 3500 trucks (5.9L / 6.7L Cummins).

Engineered for high-performance Common Rail Cummins applications, the Fluidampr High Strength Bolt Kit provides the necessary clamping force to secure your harmonic balancer during high-torque operation. This kit is specifically recommended for engines producing up to 700 hp and 1,250 ft-lbs of torque, where factory hardware may reach its structural limits. By utilizing premium hardware and a specialized friction interface, this kit ensures the damper remains indexed and securely mounted to the crankshaft snout.

• Manufacturer Part Number: 300007
• High-Strength Hardware: Includes custom heat-treated bolts manufactured by ARP® for superior tensile strength.
• Friction Washer: Features a diamond-impregnated friction washer to increase the coefficient of friction between the damper and the crank gear.
• Performance Rating: Validated for applications up to 700 hp / 1,250 ft-lbs torque.
• Direct Fit: Designed for 5.9L and 6.7L Cummins engines (2003-2023).

Fits select 2004-2019 Cadillac CTS-V, Chevrolet Camaro, Corvette, Silverado, Tahoe, GMC Sierra, Yukon, and Pontiac G8/GTO with LS-series engines.

High-performance GM LS engines often require pinning the harmonic balancer to the crankshaft, as the factory crank snout lacks a keyway. For supercharged or high-RPM applications, the Fluidampr 300004 Drill Pin Kit provides the hardware necessary to create a secure mechanical lock between the crankshaft and the damper, preventing the hub from spinning or slipping under load.

This kit is designed for accuracy and ease of use, featuring a dedicated drill fixture that bolts to the crankshaft to ensure perfectly aligned holes. The included hardened drill bit is sized specifically for the provided press-fit steel dowel pin, creating a robust connection that eliminates the risks associated with a friction-only fit.

• Prevents harmonic balancer slippage on non-keyed LS crankshafts
• Precision-machined drill fixture for repeatable, accurate alignment
• High-quality drill bit sized for exact press-fit tolerances
• Includes steel dowel pin and fixture holding bolt
• Manufacturer Part Number: 300004

Fits 1994-2023 Dodge Ram and Ram 2500/3500 trucks (5.9L / 6.7L Cummins).

Secure your harmonic balancer in high-performance or competition applications with the Fluidampr 300002 Drill Pin Kit. This kit is specifically recommended for 5.9L and 6.7L Cummins engines that regularly exceed 3,500 RPM. Pinning the damper to the crankshaft prevents the balancer from slipping or spinning on the crank snout, protecting your engine from timing issues and potential crankshaft damage during rapid engine acceleration or high-torque loads.

The Fluidampr kit features a precision-machined drill fixture that ensures perfect alignment with the pre-drilled pin holes on your Fluidampr unit, allowing for a professional-grade installation. The included hardware and tools are designed to handle the hardness of the OE crankshaft for a reliable, press-fit finish.

• Manufacturer Part Number: 300002
• Prevents damper slippage and crankshaft keyway failure
• Recommended for engines exceeding 3,500 RPM
• High-strength steel press-fit dowel pins
• Precision alignment drill fixture
• Includes drill bit and reamer tool
