TIB = Twin I Beam?
TTB = uhhhh iono Twin Traction Beam (for out back?)


How do they control the forward to backwards movement on front suspension setups like that? Seems like with those long arms there would be quite a bit of leverage to let the tire move forwards and backwards...
 
Yes on both of the descriptions. TTB was the 4x4 version. Dana 28's and 35's under the Rangers/Bronco II's/Explorers/clones, Dana 44's under the F150's and Broncos, and Dana 50's under the 3/4 and a very few 1 tons.

The coil sprung small trucks and half tons all had radius arms leading from the beam back. You can see it in the picture taken from the rear d-side of the truck. The factory length arms were all notorious for being a bit short but make them longer and suddenly HEAPS of travel was unlocked. Similarly elongating the beams and mounting them at equal points on each side gave the vehicle LOTS of downtravel.
www.AutoFab.com is a specialist in this sort of suspension.

Somewhere a decade or so ago I saw an article about a guy who had put a Dana 44 TTB under a Suburban that was a desert truck. Might have mentioned that before. Can't remember where I saw it though.
 
Hmmm thats pretty cool... I wonder why I haven't seen more of this setup when we're out in the sand...
 
Other than Econoline vans it hasn't been sold new since 1997. Everyone has A-arms under their 2wds and IFS 4x4's.

A-arms can only get the sort of down travel that is possible with TIB and TTB if you use really long A-arms or find a way to move the engine back and mount the A-arms centrally like the race trucks and buggies.
 
Found a couple more pics from last time we were out in Oceano... this was a nice rig...

I like that truck but I think I would want something a little more dual purpose. It doesnt look like it has enough ground clearance anymore because of the way the suspension is set up. I would want it setup closer to Kevin's rig or maybe more like ktmoutfront's rig. Speaking of which is there anymore pics floating around of ktmoutfront's blazer?
 
There's some on his photobucket...

Yeah I see what you're saying about being dual-purpose but at the same time if all you do is sand then why not go all out? Keeping the CG low like that probably helps quite a bit... from his speed and the way he sounded I bet he had some serious hp.


Man all this is making me want to do a big CK5 Pismo meet and greet... hopefully we'll get one together soon enough :)
 
If all you wanted to do is sand then I would just build a sandrail and keep a 4x4 truck to pull it to and from the dunes. I love going out to pismo with my blazer but its really hard on it because its so heavy. I would love to build a truck like the one in your pick but then what would be the point of it having 4x4 if it cant really use it somewhere else.
 
Yeah but I don't have a 4x4 to tow it with so by the time I bought that and a sand rail I'd be in it for quite a bit... I'll do a sand rail down the road I'm sure but for now I'm really interested in building a truck...
 
wheel travel...
...quality not quantity.


good shocks and springs go a long way.
 
heres my 79 at ols hill in glamis. i ran it in 4wd most of the time although i didnt need to. i had no trouble going up olds other than the whoops, had to basically idle most of the way up the hill then i could get on it. duning a full size is no big deal if you know what your doing. i have taken my f250 superduty deisel in the big bowls at glamis(rescue mission) you just gotta pick your lines before hand.

Nice truck man! Member since '04 and only 2 posts? Where have ya' been? :)

So are the paddles worth it on the back or should I just stick to 4 BFG AT's?
Also where did you get them?
 
i have been a lurker here for a while, decided to pay the fee so i could see some pics here. im more of a desert guy since my offraoding consists of glamis and the desert in barstow lucerne valley, etc.

bfg a/t work really well aired down to around 12psi, thats what i had on my superduty when i ran it in the dunes.

my blazer didnt need the paddles, but i figured what the hell and put em on. i got them from suspension unlimited in ontario, you can also get them from fulelrton sand tires. the blazer throws a helluva roost in 2wd with these paddles. they are 35inches tall too to match the front tire height. helps to have the power to turn em too though. ive had my blazer since 1989 and been messing with it ever since. right now its got a 2in lift on it, crappy rancho shocks, 4.10 gears front and back with a locker on the rear, 400sb with scat rods, dart heads, roller cam, and all the goodies to break drivetrain parts lol. i am planning some serious suspension mods to help the ride in the dirt, leaf springs suck lol. looking at either a 3 link with coilovers or something like that total kaos setup. still figuring out what its gonna take to do all the stuff i want. im also looking for a 73-75 blazer for parts, mainly windhsield fram and top and a clean title.
 
Cool... yeah I learned from other members (username chevyin) last time we were out in Oceano that the BFG AT's are an INCREDIBLE sand tire when aired down... thats what they ran on the '80 k5 they brought out for the weekend and I was blown away...

Thanks for the heads up on the paddles...

Oh and check the for-sale section. I know there are a couple trucks for sale that meet your needs from a SoCal member... he's letting them go cheap too...

Thats the most fun I have ever had in the dunes. A buddys bike broke and another freind who wheels his fullsize bronco in the dunes was on a four wheeler and I just followed him no worries about the lines or anything I knew if he went down something it was no problem for me. That was a blast.

Thats another thing about wheeling a full size in the dunes I have taken 3 bikes and towed a couple of rails out of places. They make nice rescue rigs
