CONVERSION TO SIX LUG
Converting the BRAT hubs from the 4 bolt pattern to
a Toyota 6 lug pattern is so easy I am at a loss as to why it never occurred to
me. But thanks to the great Hassey of the
USMB the idea was crystal clear the
first time I heard it. Back when I had my first BRAT nobody that I knew even
knew about the Pug rims. As I got ready to build my new BRAT I began to look at
wheel options and the Pugs were the first thing I found. They fit, and although
they are narrow they are 15 in and some far better than stock tires will fit.
But it wasn't exactly what I wanted. Then I saw the pics of Hassey's BRAT and
those nice Toyota alloys. I assumed that he had swapped the BRAT body onto a
Toyota frame, or had some bizarre and expensive $1000s) machine shop item. Well
no stupid, it costs a few bucks and can be done in minuets. The short version is
this: Bang out two studs (across from each other) from the hub/ brake drum. The
remaining two fit perfectly into two of the holes in Toyota type rim. From there
you just drill out the four new holes and bang studs in from the rear. You have
6 lug hubs that will fit any Toyota 6 lug rim. Why you ask? Because there are
about a million 15 inch rims with that bolt pattern ranging from mild and basic
to wide beadlocks with built in central tire inflation control.
1. Remove hub/drum from the truck, clean it up, and mount it on
2. Use a punch to mark the center of the hole and give the drill
bit a starting point to prevent wander.
3. Drill the hole the same size as the other holes and bang in
the studs till they grip.
4. Use a nut to tighten up and pull the stud into place.
While the above option is easily reversed and you could
fit the stock rims again by moving a few studs some folks are just not going to
make that mod. Another method that some love and some hate is to follow the
above procedure but instead of drilling through the hub you drill two new holes
in the rim and convert the Toyota 6 bolt into a 4 bolt. Now one can argue all
day about which is better for a number of reasons. While either one is good, I
personally fell in with the 6 lug camp.
My final choice in rims was the U.S. Wheels 70 Series because
they look a bit like stock BRAT wheels. The price on these is not bad either
ranging from 25. to 55. from Summit Racing.
The size I chose was 15x10 to accommodate the Super Swamper 30x11.5. But you are
free to use just about any Toyota 6 lug rim. A word of advice, backspacing
dictates offset and clearance behind the tire. Most Toyota rims are 3.5 in or
close backspacing and this combo has worked for Hassey with 31x10.5 and myself
with 30x11.5. I would presume other sizes to work as well but remember that the
rim width being wider will prevent balooning and help to insure that the tire
does not go beyond the rim too far.
