Review on BBK 1555 Underdrive Pulley Mustang by Duane Kerr

Revainrating 5 out of 5

BBK 1555 Aluminum Pulley Kit for Ford Mustang GT/Cobra 4.6L -

I am a manager. at a small used car park and today our mechanic installed it for me. I also recently installed Backend 3.73. The difference in performance is big, even better than just the rear end. The investment is worth it.

Pros
  • Ideal for a small home
Cons
  • Some difficulties
