Hey guys, for those of you who are informed probably will view this as a noob question, which its.

Trussing an axle. Whats the purpose of doing so? One good rule of thumb I always use when modding, if you dont know why you need it then you probably dont need it. But I always like to make sure I dont regard that statement in ingorance. Before I pass on something I might not need Id still like to become fully informed on the matter.

I ask because I have a F8.8 and hopefully soon a D44 for the front that I plan to swap in the very near future. So while Im welding on spring perches and shock mounts might as well weld on this truss system while Im at it (if need be). Im looking at the one offered by Iron Rock Offroad:

depends on how hard you wheel it, how big your tires are and if you are locked. but a truss basically stiffens the whole axle housing and prevents twisting. if you are going big then a truss is worth it.

 

OK a truss basically ties both the left and rigth side tubes together, thus strengthening your axle. Also if you upgrade to a link style suspension it gives you a place to mount your links. Also make sure you weld your tubes to your axle housings on the 8.8. Also use hi-nickle rod and pre and post heat it.


On the front you will need a trusss so you can mount your upper drivers side control arm mount. As with the rear trussing it support and strengthens it.

 

and if ur doing just light to moderate, weekend warrior type of wheeling, then u prbly wont need to truss it, but if u start getting into the heavy duty, full-time rock crawler type of wheelin, then a truss is prbly going to be needed, but by then u would prbly ditch the stock axles and go for something bigger and better

 

Thanks for info guys.

When you refer to welding my tubes on the 8.8, how so? Still new to the axle conversion world.

And as for the D44f anyone know of some good places to purchase a prefabbed truss with mounts included. Call me lazy but with my work load id prefer everything to be "plug-n-play" or place & weld so to speak.

 

Most guys I see running a truss do the jeepspeed stuff where they sometimes jump the trucks similar to prerunner style racing. This puts a lot of strain on the axles and can cause the axle tubes to break off. But the concept is the same for trussing an axle for wheeling and to run a different suspension system. When people refer to welding the tubes on an axle, they mean welding the axle tubes (part where the shafts go in) to the axle housing. This strenghtens the overall axle.

 

TNT Customs make trusses for pretty much every axle that would be swapped into a jeep, you can also have other things added on like control arm mounts, coil buckets and track bar mounts

 

The 8.8 has what is known as a plug welded tubes.. meaning the tubes are held in place by plug welds.... To prevent tubes from spinning, you need to weld the tubes to the housing.


TNT makes a pimp truss that is pretty easy to set up, but the other cheaper option out there.

 

Thanks guys for the help. Last dumb question. Im an extremely visual person. Can someone kinda pull a photo for the intertube and paint edit it with indications towards the areas where I need to weld said tubes? Sorry Im so needy, like I said, extremely visual person, words dont properly comprehend for me

 

Its all about reducing "ring gear deflection". This happens when your axle is under load the pinion forces the ring gear away from it if the housing has any flex in it at all. A truss and a heavy duty cover as well as a full case locker goes a long way to reduce this effect.

JeepSpeed guys run their truss under the axle for more support when landing, rock crawlers run theirs over top of the axle to eliminate housing flex while still providing ground clearance. In either case, it is to eliminate housing flex but the JS guys need to keep their tubes and "C's" from bending as well. If your getting air when rock crawling then you are either competing or are are just too heavy with the right foot.
