Here is some technical information on Matkins Frames
We sell four different frames for your application starting at $1350 for a
3/16 wall mandrel bent frame much like others are making except it is 7/16
thick on the bottom and gussetted to make it as strong as the stock frame.
If you really want strength, you'll want one of our Extreme Frames. They
are over sized and fully welded just as is required in NASCAR and Super
Trucks where mandrel bending is banned. I'll explain the differences and
Unlike all the other frame companies on the national market we use OVERSIZED
rails. Those smaller companies sell UNDERSIZED rails made of nothing more
than a 4x2 tube. To avoid admitting this they talk about wall thickness only.
Jeep never made a box tube rail that small. In 1976 Jeep started using a box
tube design. They made the rails exactly 4 1/2x2 1/2 in the middle. The
difference sounds small, but that is 2 inches of wall missing!!! And they
almost always break in the middle if the problem is stress. The other guys
will sell you a rail that is so small it will fit inside the stock rail. We
use bigger 5x2 tube and reinforce it with solid 2x1/4 bar on the bottom. Then
we bring it down to 4x2 only at the ends. That means that our bottom line
frame with 1/8 inch walls in the tube is actually 3/8 thick on the bottom.
The end result is that our 1/8-3/8 inch Level I frame costs only $1495 and
has more metal in the middle than their 3/16 frame. At only Level I, the
cross sectional area of actual steel measures 2.12 square inches, their 3/16
is only 2.11 square inches. Our 3/16-7/16 inch Level II frame has 2.98 and
the 1/4-1/2 Level III has 3.75 square inches. And because our rails are 1 1/4
inches taller, they have 31% more leverage than the little rails offered by
those smaller companies and 16% more than stock. At $1695 for our Level II
frame you get 41% more steel in the middle than their big 3/16 inch model.
The Level III at $1895 blows theirs away.
Weights are a good way to compare our Extreme Frames to the stock frame and
each other. The stock CJ7 frame weighs about 200-210 pounds. Another company
has offered an 1/8 inch CJ7 frame that they claimed over the phone as
recently as Sept. 1999 weighed in at a whopping 175 pounds! This has
presented problems, evidently, so they now offer the same thing in a 3/16
thickness. That still leaves them with less steel than stock in the high
stress middle area. They will advertise thicknesses of .120 and .188. But if
you buy one of their frames you will not get rails that are actually that
thick. I'll explain that in a moment. Our weights are as follows: Level I,
230; Level II, 310; and Level III, 400 on the CJ7 frame.
If all else fails they say they use less steel because the frames should
flex. Isn't that why they break? C-channel frames are made to flex, not tube
frames. And mild steel will not take continuous abuse like that.
Another factor that is important is the method of forming the rail. As you
may know, NASCAR and Super Trucks have both banned mandrel bending due to
strength issues. They use as light a frame as possible for speed and the cars
get a lot of strength from the cages. They use very light tube. So, they
require MIG welding with no ground welds, just like we do it. Of course, we
use larger and heavier material.
Bending weakens the rails three ways. First, the metal on the outside of the
curve is stretched. If you start with .120, standard 1/8, wall 4x2 and bend a
gentle 12 inch center line radius, the outside wall is stretched and thinned
to less than .085 inch. This qualifies as sheet metal and you can bet that
the other companies will not tell you this little secret. Standard 3/16
starts at .188 and becomes .135 or less.
Second, bent metal is crystallized metal. That is why an Allen wrench tends
to break at the knee. The rails will be as weak as a frame that has been in a
wreck and straightened! At EVERY corner.
Third, most bending machines leave the tube wrinkled and partially collapsed
at the corners. This is even worse than the stretching. To some extent, all
bent frames suffer from this flaw. Even most ad pictures can't completely
If you just love bent rails for the looks, we handle a frame for your
application that is also mandrel bent. The rails are 4x2 tube just like the
other guys, but with about 25% more steel so that they are up to OEM
strength. And they have the heavier cross members like our Extreme frames.
These start out at $1350 and we call these our Economy Frames.
We love the after market industry and that is why we take the time to expose
these sorts of things to our friends, whether they buy from us or not. Many
of our friends are on the national rock crawling circuit and we sponsor a
few. These factors have contributed to the trouble that 4x2 frames have had
traditionally. Perhaps these factors are why the companies with under sized
rails don't talk about outside dimensions and weights.
Now let me say a word about finishes. It is easiest on your end to have the
chassis finished after you have horsed it around and scratched it up putting
on lines, axles, and so forth. We charge $450 to powder coat it any color you
want. But it does nothing for the rust. Box tube frames rust from the inside
out. As far as I know, no plant in the country can get the inside coated. And
how do you get it clean enough? There will be cutting oil, smoke, and mill
scale inside. We will do it, but it will only protect the outside. The
competition is offering a 10 year rust-through warranty if you hand them $400
or 500 for the job. This seems odd to me since an uncoated frame will last
20-30 years in most environments.
Galvanizing is available for $425, but it presents much the same problem. The
mill scale and other contaminants are not likely to be completely removed
from the inside. Of course we only offer hot dip galvanizing, not zinc paint.
Our approach is to eliminate all unnecessary rail holes. This prevents mud
loading so the inside can dry. Then you can fill the rails with a product
like POR15. This is a fraction of the cost of other things. Or we can do a
similar treatment for $195. We offer a limited lifetime warranty against rust
through and so does POR15. We are currently using a DuPont product that is
not available in small quantities.
Stainless steel is a material not particularly suited to frames. If you use a
grade hard enough to resist rust in a salty, wet environment, it will be far
too brittle to take the shock of rough driving on a cold day. The grades that
are good enough to resist corrosion in any environment are the 300 series
grades. The 400 series grades are softer and less likely to crack, but they
will rust in a salt environment. Stainless gun barrels made from 300 series
grades may crack if dropped or fired when too cold. Again, if you are serious
about stainless steel, we will price out the material. Just be advised you
may have problems. Companies are offering stainless for rust, but have they
done their homework?
We have a warranty program like most other performance parts companies. We
warrant our frame will be just as we told you it will be, that it will fit,
and that the material and workmanship will be good. If you have a complaint
we will give total replacement, including shipping, or you can call us with
the number of 4 AWS certified welders in your area. Within one working day we
will set up an appointment and pay all repair costs. What you do after you
get it is up to you. If you get a Level I and jump a boulder, you're on your
own. We sell these to guys on the rock crawling circuit and all sorts of
other animals. I will guarantee any frame for life if you drive it on the
road, take it hunting, and the like. But most of our guys are not like that.
To put it in perspective, we've not had one rail break in the five years we
have been serving the national Jeep community.
