If you are looking for speed or strength - a dog box conversion is a great way to improve the performance of your vehicle. Streetwise has years of experience working with dogbox conversions as well as purpose built racing gear boxes. We have built and rebuilt boxes from Hewland, Xtrac, PPG, Hollinger, Modena, and others. Give us a call and we can discuss your particular needs and how to fit them into your budget if you desire to go this route. If you already have a gearbox and are looking to have it rebuilt, we offer rebuild services and upgrades such as no lift shift integration.
