Easy Bolt On Power Upgrade
BBK 1985-1987 Monte Carlo or GM Truck underdrive pulley kits are one of the easiest ways to free up an average of 8-15 horsepower in under 30 minutes. BBK pulley kits are designed as direct bolt on replacements for the current factory pulleys and retain full cooling and charging characteristics.
BBK underdrive pulleys easily bolt in place of the factory pulleys using the factory hardware. Each kit comes with complete installation instructions and retains the use of the stock length belts.
Lightweight Aluminum Construction
Not only is aluminum great for durability but it also reduces rotating weight, further reducing strain on your accessories.
