Mustang SR Performance Underdrive Pulleys (96-04 GT) Review

Unleash 10 to 15 More Horsepower. Do not underestimate the importance of high-performance and lightweight underdrive pulleys. Installing a set of SR Performance Underdrive Pulleys is an easy way to squeeze out an extra 10 to 15 more horsepower from your 1996 to 2004 Mustang. Engine accessories like the A/C compressor and the water pump will cast a huge burden on your motor, causing extra parasitic drag when they don't necessarily need to be running at such capacity. Designed to turn at different speeds to minimize the effects of parasitic drag, these SR Performance Underdrive Pulleys will replace the factory alternator pulley, crank pulley, and water pump pulley to unleash more horsepower from your 4.6L V8 up front.
Genuine Aluminum Construction. Each piece of the SR Performance Underdrive Pulleys is CNC-machined from lightweight aluminum alloy for unmatched lightness, strength, and durability. The polished finish looks good under the hood, and they give your muscle car added engine bay flash and style.
Bolt-on Installation. These SR Performance Underdrive pullies are a direct fit on the accessory that they are intented to install on. This job can be completed at home with a regular socket set. However, be prepared to spend the afternoon with your hands tucked into the engine bay as the process does take a while in order to disasemble and re-install the new pulleys in place.
