2WD Low Option with Bill Johnston |
||
 Your stock shift pattern doesn't have a 2wd low position?
Aaaahhh! Time
to see the guys at Petroworks for the upgrade that will change your way of
driving.
The best time to do this shift pattern conversion is when you already have the transfer case apart for maintenance. This case needed some new teeth on a couple of gears, so we did the conversion while putting it all back together. |
||
  The only component that needs to be reworked is
the small shift fork. There is a little grinding and a little welding to
be done, but it has to be done right. The fork on the left side of both
photos show the converted component, the fork on the right of each photo
is the stock version. |
||
 Check out the diagram that comes
from Petroworks for the appropriate changes. While it is possible to do the upgrade on your
own, it is much easier to let someone else do the grinding and welding
needed to re-engineer the shift fork for this application. Petroworks has
had this component available for over five years now with over 600 units
out on the road. They also offer this conversion (free of charge) to any
customer that buys a GRSIŠ or GRSIIŠ transfer case from them. Gary Munck,
owner of Petroworks, says that (to date) they have only built two of those
transfer cases without the 2wd Low conversion. |
||
 If you are comfortable about replacing the fork
yourself, this is the way to go. If you have any doubts, take it to a
reputable 4wd shop or get a case that is set up from Petroworks. This is
not the kind of project you want to 'practice' on...
But when it comes out right, you can amaze your friends and make the unknowing cock their heads like puppydogs when you walk through an obstacle in 2wd! |

You are driving down the trail in 2wd, nothing tough yet, you haven't
even locked the front hubs... coming around a corner you are confronted
with a hill that you KNOW is going to be tough in high range. You know
you could make it in 4wd, especially with the new locker you put in the rear
last weekend, but do you really want to get out and lock the hubs? That
lower range would be really nice right about now. As the crowd gathers
behind you waiting to see if you are going to break down and use 4wd, you
shift the transfer case into 2wd LOW and climb the hill without a
problem.
