Custom MGT/MTA4 Upper A-Arm mounts This page authored by TheDude, owner of TD Racing ------------------------------------------------------------------------------- DESIGNING THE MOUNTS The design took on many forms and model types throughout its creation. In the end a mount was developed that required no modifications to your MGT. Computer stress analysis testing before machining,
A simulated impact load strong enough to break the upper A Arm was applied to both mounts. The deformation of the TD Racing mount was .0043 inches vs. .0090 inches for the stock. In layman's terms, the new mount is twice as strong and it will not bend. The a-arm will now break BEFORE the mount bends! Stress analysis,
A look at safety factors showed the stock, (bottom) failing in red and the TD racing, (top) surviving under the same shock loads. ------------------------------------------------------------------------------------------- The final product design was prototyped and stress tested. CLICK here for a video, showing real world testing! First, using a stock mount, I hammered until the a-arm broke (the stock mount was bent and binding). Then I decided to get the camera out and take some video of the TD Racing mount while I smacked the a-arm that was mounted to it. In the video, the stock has already failed and its a-arm broken. I wanted you guys to watch as I hit even harder on the a-arm that was connected to my mount until the a-arm broke, then witness the freedom of the TD Racing mount. Replace your arm, (If it did break), and your ready to go! The bench test results were this;
As the hits got harder the stock mount bound and seized more. The TD Racing mount never bound in the test, even after the A-Arm broke from the impact. Now proven durable in design and bench testing it was time to run them on the MGT! Some prototypes were then machined and sent to field testers to forum members in NJ and TN. The feedback was great! No binding, bending, seizing of the mount and suspension no matter how hard and high they ran their MGT. Now confident and convinced of the durability, we machined, anodized and delivered 30 sets of two to various buyers around the world.
SOME CUSTOMER FEEDBACK; Forum member, (snook)
"Just got home from work, hanging there on the front door. Look
pretty good,
fixing to put them on and maybe get a run or two in. I appreciate your time
and effort on this, not many people would do what you have done." TeCk
"Ok well i took 2 of the best brackets from my basher for my
racer. Headed to the LHS they have a little track there. Fronts, (Dudes) held up
great. Sad to say rear ones, (STOCK) didnt hold up long. I was really hard on
the truck to test them out. Front didnt bind, drag anything they are perfect. I
only wish i had 4 or lest 1 more so i can put on basher and give her some super
air jumps. I want to break a-arms off to do a good test. AE sent me my tranny
parts today so minus the braces ill be readdy to run some good tests. Im going
to move the dude ones to the basher and wait for my set of them i got off ebay
for the rear. I will keep you posted. I hope i have before the weekend.

Here's a quick pic of stock mounts and TD
Racing mounts: If you're one of the many that is frustrated with the stock mounts, now you have a choice. Many have emailed me (TheDude) stating that since they had their MGT they have bought 6 to 15 sets to replace these mounts. Also some have resolved to buy stronger hinge pins to assist the stock mount from bending. This is unnecessary as your stock hinge pins will work just fine. Fact is, if the mount does not bend than the pin will not bend, one less thing to worry about and pay good money for. The mounts are sold in sets of two
