These shafts run through the motor from the transmission to the front differential. The stock part tends to break pretty often...so, here's one that will hold up to Gorilla Axle-Sized abuse! The Gorilla Axle "Through" Shafts require no modifications to the engine cases and it is made of 4340 Chromoly Steel (the same material Gorilla Axles are made of).
The Gorilla Axle Can-Am "Through" Shaft replaces OEM Part Number 420620515.
