4 link ttb

[alwaysFlOoReD]

Yes, unfortunately it does sometimes seem that way. Legally, anything with over 10cm of suspension height over stock needs to be inspected....seems to be hit or miss with cops around here tho...I've never been bothered with my truck around here, but it doesn't look like a cobbled together POS either...

Who does the inspection? The cops, icbc, independent mechanic?

cops will write up an inspection notice,a mechanic registered with the province will do the inspection.i was writen an inspection notice,the cop gave the reason as being that i had a heim joint in my rear suspension.i didn't question it,just changed it out for a poly bushing and had it inspected.it passed,and i was under the impression that hiems were illegal from that point on.

hey gwaii, where did you get the idea to do this? i cant find anyone else in a rbv that has it... so i showed my buddy the tube today, 1.5x .5 wall, and he said, "Good Lord, this thing could hold a car up!" So of course my response was, "Thats the whole point...." But seriously, now im thinking about replacing my factory steering, what do you guys think about crossover type steering? thanks for any ideas...

the idea came from my thought process.

thought...i want a long travel suspension.
thought...gee,that's going to result in a lot of negative caster at full droop.
thought...i wonder how i could avoid that.
thought...hmmm.i bet a 4 link on the beams would do it.

the rest is history.

as for crossover steering,it's a hell of a lot of work,do your homework on the geometry....and it cant be beat.all those who've 'improved' their steering with other systems would not believe what a difference it can make until they drive a crossover type.

I'm guessing that laws and regulations are as different here from province to province as they are state to state. As far as lift laws here, they give you some kind of mathematical formula to figure out if your vehicle is legal or not. Then they go on to say that "any" suspension modification is considered illegal. When I read that, all I could think was... "they give you a formula then proceed to tell us that we can't??? SHEEESH... what one is it man???"

Yes they are different from province to province. The only real rule of thumb here is anything with suspension modified over 4" of lift needs to complete a motor vehicle inspection. Other than that...the usual stuff....tires fully covered, headlight height laws. Not that bad.

my thread has been jacked by legal issues... lol, so in your opinion, if i take the time to do it right the crossover is worth it? ive never drove one with anything other than stock so... do you think theres a big difference between the superlift and crossover? i also look into the stonecrusher, i think thats what its called, to me it dont look like its worth the effort, but i dont really know.

Its great to live in Alabama, you dont have to have a windshield, although you are required to have wipers...

if it's worth it depends on you,and what you want to do with it.if you have ANY intention of becoming airborne,yes-it's worth it.superlift,it's a good base to build a crossover out of.in it's out-of-the-box form,garbage.you are better off with the stock set.stonecrusher is better than stock,nothing compared to crossover.

edit-the one issue i have with the stonecrusher setup is the heims.legal or not,i don't trust them in a street application.street vehicles don't generally get the attention to maintenance that race rigs do,and without constant attention the hiems wear much faster than tie rod ends,and fail in a fashion that gives less warning.some may disagree with me on this,but i'd prefer to err on the side of safety.

This concept has been around for years. The old rough riders F-150 that Robby Gordon drove had this setup. The Sato Brothers also run this setup on a F-150. This setup has to be run with heims at at least one of the pivot ends per link. Poly bushings at both ends will not provide the deflection needed. It is an amazing setup due to fact you can build it to obtain your desired degree of caster at ride height, full droop, and full compression..

go to polyperformance.com for links and hemis and stuff like that.

I know this thread is a year old, but I think this is something I may try.

exactly. the only thing a TTB lacks from a 4 link is caster control. You've accomplished that with yours so there's nothing else a 4 link has to offer. If it was even possible.

Not exactly, 4-link has more to offer than just caster control. You can set up the links so that when you hit the gas the frontend doesn't jack up to the moon. Which is a characteristic of radius arms that I hate. You can set it up so that the frontend stays level or even make the frontend squat under acceleration.

I can get some 1&1/2 with .250wall dom from a buddy, do you think that will be strong enough?

That will be plenty

Radius arms don't cause the front to jack (if you're in 4WD they actually have a slight opposite effect). It's on the rear they tend to cause jacking issues if they aren't made long enough.
What you're describing sounds much more like the result of the steering linkage angle being pulled up out of whack (pulls the toe alignment toed-in as it rises, which then causes the tires to drive inward toward each other, jacking the suspension up even further like a scissors lift). I'd be looking for something along the lines of a pitman arm that's too short for the lift being used in this case.

IDK, every radius arm rig I've ever wheeled jacked up in the front when accelerating even with a straight axle front. I've got a 3-link on the front of mine now and it stays level even when accelerating up hill
