4400 Series Truck Pull: Chevrolet 55-85 SBC: 70-90 BBC: 1-1/8 x 26: 168T
The 4400 Series clutch system from McLeod is ideal for Truck Pulling and high horsepower sand drag applications. Recommended for non-shifting motorsport applications. This series features a Borg & Beck/Long pressure plate assembly, unique to McLeod that also includes counterweights providing additional high RPM lockup capacity. Steel flywheels are included with these systems along with low coefficient friction sintered iron discs. Due to the pin style drive on the floater plate, these multi disc clutches are not suitable for street applications as they will be very noisy at idle and low RPM.
