Wheelbase vs trailing arm length
- Thread starter SteerAndStuff
- Start date
I have another question for you guys in this thread. Can anyone give me the pros vs cons of the TA vs a regular link? What's the good/bad of mounting the shock to the TA vs the axle? While I've been testing the length out I mounted some rtr yeti rear shocks to the axle and it's performed pretty well. Im going wraith length for sure because I can still turn off the drag brake and go bouncing around.

Simple geometry.
You might be able to do axle mounted shocks with the TH lower links, but longer than that, your shocks will be WAY leaned over and not work well. That is unless you could figure out some way to move the upper shock mount back further on the chassis.
I was thinking about using the rear upper mount. I like how much less hang up there is with a regular link compared to the TA. Just exploring my options before I spend $50-$70 on trailing arms. I definitely like the crawl ability with the wraith length rear end over the stock length

Give it a try and post up pics.
After moving around the spare tire mount yesterday on my bomber, i realized how much better it crawled without constantly getting hung up on the rear tire. Then i went hmm, like a half inch shorter rear and linked instead of TA's would work well....
Only thing would be rear shock upper mounting position I think they would need to be further back and possibly lower than the stock upper rear secondary shock mount

LOL aint that the truth..... im sitting here at work chained to my desk to answer phone calls for the next hour going.... well if i do this... wait can i??!??!??????? Then trying to find pics online that would show me clearances.....

You wont need to keep the rear sway bar if you mount the shocks on axle. Jec racing has a shock mount that adds a ton tuning abilities. Or boom racing sells an aluminum shock mount with more holes too.

I just made straight lowers that are 1/2" shorter than stock so about wraith length, and moved the shocks to the axle. It gave me too much up travel and no down travel so I shaved the eye off my top caps and extended them axial log rod ends. Now I am at about 50% up/down at ride height but my ride height is lower than stock. I have not driven it yet but it feels good on the flex test

Another option to mount the shocks on the links is to run what XR10s used to have. AX80059. I was planning on trying this if needed, depending how angled my shocks would be.

If my setup does not work out I plan on mounting my shocks above the straight links like that but I will just weld tabs to my links.

I found this photo on Google images. I can't get over the fact that your Bomber with the TH links is so friggin' awesome looking!!! "thumbsup"
How well did it perform? And what wheels are those in the photo?
Has anybody put triangulated 4-links on the rear of the Bomber?

After our previous conversation I did some digging. Seems triangulation is gonna be the issue if you run straight links utilizing the stock bomber skid. This can be overcome by utilizing a wraith skid, although the transmission and transfer case mounting holes will need to be drilled. Yet to try any of it obviously, but seems pretty straight forward.

New here. Sorry for the question if I missed it from the previous pages even if I read all of it.
What will happen to the drive shaft (from CEnter diff to Rear diff) if TH lower arm and shorter upper link will be used?
Is it possible that someone will list other changes that is needed if TH arms will be used?
Looking forward to a shorter wheelbase.
Thanks.

You can cut down the stock driveshaft.

I pieced mine together from "extra parts" that were on the parts tree that came with the car.

Spotted these on fleaBay. They're for the Twin Hammers clone.

Nice looking pieces. That said, look at the pressed in rod ends. Doesn't look like you're going to get much articulation/flex out of them.
Thinking outside the box here for a second; why not build an arm that is the shorter length, which can also mount the shock slightly behind the axle solving shock length issues? Then re-do the upper link mounts moving them closer to the rear axle which would allow you to tip the pinion up to raise the drive shaft. Yes you'd have to do some geometry in order to recover the pinion angle at full bump, but you'd gain ground clearance. Heck, you could alter the front while you're at it if you wanted. Maybe I'm thinking too far outside the box.... :roll:
