Strange Engineering are an excellent choice for street/strip, circle track, and off-road applications. Ensure your vehicle's full power potential makes it to the ground with equal distribution. These are some of the strongest and most durable locking carriers available. Clutch-type differentials from Strange Engineering utilize specially machined clutches, aircraft-quality steel side gears, and are quieter than one-piece units. These differentials are ideal for street use, and they can be rebuilt.
