Long Travel BS Thread

If you google for a link geometry calculator there are a few free programs you can download. Can't remember what they are off the top of my head, but I did mess around with one a while ago

 

Most likely not

 

They use that air shock in place of an upper link bar to control pinion angle. . Running an upper link is a far better than the air shock setup. Lots of guys have had issues with the air shocks and switched to an upper link

 

Gotcha, I was wondering where the upper links were -- I wasn't sure if it was an in-progress picture or what. Optimally I would do a standard 4 link, not that weird air system. That seems strange -- any idea what the advantage would be?

 

Not lighter. Lots of companies like solo use a peice of dom running the full length of the bottom of the links.

 

You don’t need to mount an upper link. In theory makes for an easier install, until you start blowing up driveshafts

 

Makes sense. Thanks for the good info.

 

couldn't they just use one piece of DOM tubing with mounts for the coilover and bypass, is it required to be boxed you think?

 

Tubing is general for a rock crawler as they have their shocks/coilovers setup much differently. Typically mounted directly to the axle.

Long travel will mount to the lower arms thus giving you a different lever ratio and allows you better tuning for faster shaft speeds. Because of this a LOT of force is put on the arm so it needs to be well..a big ass arm to stop the steel deflection which in turn means the shock is doing the work and there is less variables for tuning.

A full 4 link is better but you have to consider your fuel cell as the stock tank will not work with a 4 link so you have to do a cell.

 

Makes sense. That is probably going to be the hard stop for me. If i can avoid moving the tank, that is appealing.

 

3 link is your only option then. Which works well too. Just has axle swing due to the setup which can be minimized to a point.

 

Cool cool. I will do some drawings today and see what I can come up with. Probably a bad idea to start thinking about this but what the hell, right?

 

would you even notice axle swing on a tacoma?

just assuming it's not a fully gutted race truck

 

you can buy 3 link kits relatively cheap and go from there.

 

I've never been in a taco with 3 link. Can feel it in 4runners though.

@Evenflow setup is super cool as its only a 14'' CO under the bed and pulls 20'' or something. Its a 3 link and Im sure he can answer that question.

 

Yeah, his is what prompted me down this road.

I really like the fully intact bed, and 20" is pretty crazy.

 

They could, but they would still need to bent to mount the c/o’s and bypasses below the centerline of the pivots. They would also be pretty weak. When you put a coilover and/or bypass in the middle of the link you are adding a lot more force onto the links than if they are just locating your axle.

 

Well shock mount location for starters...crawlers dont usually put the shock on the link and dont cycle the same amount of travel.

The reason trailing arms are soo beefy is the leverage of the shocks is in the middle of an arm and the jarring forces of hitting things at high speed puts alot of stress on the links, whereas a crawler is just flopping around thru some slow rocks the stress isn't the same

 

run the ruffstuff URC trailing arms. cheap, light, strong and will work for both go fast and crawling.

 

Those are remarkably affordable
