Welcome to HermTheOverdriveGuy.Com.  I run a small company officially known as ATV Mfg. With my personal attention I can offer service and low prices unmatched by other companies.  My specialties are new and rebuilt overdrives for Jeeps with the Dana 18 transfer case.  I can also rebuild your existing overdrive for a very reasonable fee. Apart from overdrives I also either Re-manufacture or rebuild almost every transmission and transfer-case that was ever put into an early Jeep vehicle.0605bf80

Get Involved!  Join a club and meet some friends and enjoy an opportunity to learn.  Four wheel drive clubs are very helpful for an avid and a novice four wheeler to belong to. The members will know where you can four wheel legally, information about playdays, and races that are held in your area. You can learn proper skills of four wheeling so you can minimize the possibility of getting injured (both your self and your family and your rig). You can learn the importance of a winch and how to properly use them so you don’t get hurt. The usefullness of air pressure off road and four wheeling skills. Find a club in your area and join for a lot of fun. I’ve been a long time member of the Vancouver 4 Wheelers.  Please take a moment to visit their site if you’re interested
