Default trailing arm upgrade

for a cost of 21.99 per arm and a couple of bushings you can have trailing arms that surpass any upgrades currently available. If you have a tractor supply or cal ranch store near ypu then these are readuly available. All others must order them.

Parts list of what youll need
2x toplink cat 1 part number 0267759.
The bushings will have to reduce from the 3/4 in bolt hole. So for the rear bolt i used 3/4 to 5/8 bushing (also found next to the links) part # 0269002 x2

The front bolt for the actual bracket, i chose to make accept a 1/2 bolt which required a very slight reaming of the bracket. Its on you how far you want to offsett left or right to cleqr your tires. Im on 245s in the rear 7"rim standard gxp rim.

Bushing will need to be from 3/4 od to 1/2.

Other things i should lve bought at the time were nuts for both rod ends to keep them locked.

Anyway this is how it all came together.

Benfits, if any?

I just changed out the bushing in my trailing arms. The arms were in great shape along with the bushings that came out.

Oh and change out you lateral arms!

That is what is used to turn the tube. Notice the small hole in the center?

Just a word of caution... Many in the Fiero world have experimented with rod ends on the trailing links and they normally break from the impact loads the trailing link sees. Every pavement seam, every pot hole, every bump in the road is transmitted through the trailing link. One guy who ran poly in the trailing link for a decade ended up shearing off the mounting bolt on his trailing link.

So I stick with rubber bushings for the trailing links (and run rod ends on the lateral links).

It was my understanding with trailing arms that on our app that only really takes loads undee hard braking and keeping the lateral arms straight at all times. The lateral arms were what i was ginna make poly. But as always i will follow up

The trailing link is the only link to maintain fore/aft placement of the rear wheel. So it sees all acceleration, braking, and road irregularity loads.
