The Stop Shop's harmonic balancer mounting bolts are designed to provide robust and reliable fastening for the harmonic balancer to the crankshaft, contributing to improved engine performance and longevity. By providing maximum clamping force, these bolts ensure the harmonic balancer remains securely attached to the crankshaft, preventing slippage or movement. A correctly functioning harmonic balancer absorbs and neutralizes vibrations generated during the engine's power strokes, preventing stress and fatigue on the crankshaft. Secure bolts ensure the balancer can perform this crucial function effectively. These bolts are designed for specific engine types, such as small block Chevy or GM Gen III/IV LS series engines, ensuring a proper fit and secure installation.

Tractor pulling engine builders long favored Fluidampr parent company, Vibratech TVD heavy-duty viscous dampers. Fluidampr now takes it further with 35 years of experience developing dampers for professional motorsports. The result is exceptional, long -asting crankshaft vibration control for today's top Pro Pullers. In comparison, the new Fluidampr Competition Series tractor pulling performance dampers surpass the Vibratech TVD heavy-duty damper in competition use. The Fluidampr design meets SFI 18.1 safety specifications for high-rpm structural rotational integrity. Inertia mass is roughly 10 percent greater to optimize vibration control for higher torque. Additional internal components compensate for greater thrust loads. Overall, thicker steel and laser welding the housing creates a single-piece design for superior durability under high torque and horsepower. The dampers also feature a more robust, 12-bolt on 4.5 in. b.c. mounting flange. The universal fit design requires a taper lock hub with 3.25 in. pilot. These harmonic balancers are available with or without pre-drilled bolt holes.

Designed just for mildly built small block Chevys and Fords Streetdampr harmonic dampers use silicone fluid in a sealed, laser-welded housing to control crankshaft vibration at all engine rpm, just like their race-ready brothers. That means more accurate spark and valve timing and reduced bearing and valvetrain wear. About the only difference between the Streetdampr and Fluidampr is that the Streetdamprs aren't SFI-approved for racing--well, that, and their lower price tag.
