GForce GSR DogBox Transmission 4 Speed

The G-Force GSR is absolutely the end of the line in terms of absolute strength and performance from a 4 speed racing transmission. With its single rail and internally shifted design no other transmission offers the GSR’s uniqueness and versatility. Like the GF4A, the GSR offers both a dual bearing center support and an integrated mid plate. Similarly, the GSR offers an internal oil pump of its own that is very similar to the GF4A’s, but unique to the GSR nonetheless. However, an additional feature found on the GSR is its internal shifting mechanism.
