Class 8 Stretching

I'm thinking of buying a class 8 tractor and having it stretched and adding a box. Does anyone know where I can get this done in the Michigan, Ohio or Indiana area? Do you have an address or phone number and a contact person? Have they stretched trucks for you? Does anyone know the name or number of the place that does it for Fyda in Colubus Oh?
Thanks for the Info!!

You want this done correctly the first time. I recommend G-Tec in Detroit Michigan there number is 313-841-1633 or 1-800-322-4832. Good luck with your new big truck.

I was just coming in here to post the same question. I'll add to it how does it cost? and what kind of box can they use? i know its got to be cheaper to buy a tractor and have them do it then to buy one from lets say fyda. thanks if you can help us

You might check the price of buying a new glider and getting running gear from a wreck . Has anybody done that ? I've seen some Class 8's with the box out about 6 ft. past the axle . I have to wonder if they get over on axle weights with heavy loads .

I also wonder if you have to be certified to do that kind of work. If not it would seem that anybody could strike an arc.

The point about "done correctly the first time" is a good one. I've often wondered what "done correctly" really means. When you stretch a tractor into a straight truck, how do you know if you're getting a professional job? How do you know that you are not altering the truck's geomotery in ways that will lead to problems or sub-par performance later? How do you know that Bubba "The Torch" Willfart isn't the man doing the work behind the scenes?

I don't intend this as criticism. The above questions are part of what motivated Diane and I to buy new instead of used. But many people do stretch trucks or think about it.

What are the do's and don't's?

I would be afraid of the results of a stretch. I've heard of things like the drive shaft angle being slightly off and causing extra wear as well as lower fuel economy and other problems. It might be a good idea but I'd be afraid of a class 8 or any other that wasn't original from the factory.

call bill moore at tsi and buy a new western star already to go
and rails are done at the factory to right lengh you want or
he is able to stretching to and does great work for a fair price
his number is 800 388 3850, and if you want a genset or liftgate he is able to do that to

For mhoy and Tom, thank you for the kind words.

For the other replys, I will offer a small reply.

In stretching, or altering a truck in any way, there is a certain degree of science involved. (But it doesn't take eleven guys) I start with weighing the truck as is.

I want to know the weight on the front end. I NEED to know the weight. Next thing is to figure the size box desired. That makes a hugh difference in the rear axle location. Also time to figure overall legenth. Legal at this point?

Stay within the legenth law at all cost.

If I'm satified with total legenth, then I figure rear wheel placement. Wheelbase and overhang. Tag-axle location if requested for a single axle unit. Same with allowing the weight of a liftgate if requested.

Point being that I will know the weights before I begin. I will know where the box tops the cab. Can I fit a refrigation unit in?

Before I turn the first bolt, I know what I expect it to look like. I know what the weights will be, within a few pounds.

Frame rails are indeed new. Both the outer rails that are seen, and the inner rails that are not see. As are the cross members added...I know before I begin, how many I need, and where I need them.

As to the driveline...lets just say I can do my job. Driveshaft angle, rear end pitch...it's all measured. Figured & refigured. Carrier bearing placed.

Let's put it this way. I build 5-second wheel-standing race cars. 750 horse engines. I've built more show cars than I can remember.
I know how to do what I do.

In cutting a frame, the truck is locked in a jig. Preventing it from moving. Perfectly straight. You're right...when I launch a drag car pulling 5 G's on two wheels running 135 mph, I DEMAND to know I'm going straight. Or I'm dead.

As to the welding...No, I'm not a certified welder. But the man who does my welding is. Professional. Neither am I a CPA. But the man that does my taxes is. Now, what was your point? I'm not a doctor either. But I 'm smart enough to know when I need one.

I'm not looking for an argument here. No long drawn out discussions. Sure enough, the total aligment on any truck can be out, LDB. Not just one that was stretched. That's why line-up shops are in business. And I'm talking to you LDB. Make no mistake. I would think any semi-intelligent truck driver would notice an odd tire wear pattern. And have his equipment lined up. Total aligment. Common sense. Don't know about you, but if I have to put steer tires on, I run it through a line-up. Maybe I notice the truck pulling one way or the other...just use common sense.

And A-team...you my friend, are dangerous. Do you even have a clue about owning a truck? THE FIRST CLUE? How many trucks have you owned? Is ZERO the correct number? Owning a truck is a lot different than driving for someone. Ask people that actually own trucks...they do what they've got to do. And they do it the best they can. Don't misunderstand me A-team. There is nothing wrong with being a driver on someone else's truck. But why not be honest, and tell people you don't have a clue about owning a truck?

Now, I don't know how to add all that fancy stuff under my name, so I'll just list it here one time, and one time only.

I need to apologize to Glen & George

Both of you gentlemen gave excellent advice. And I certainly have no problem with that. In no way was anything in my post meant towards either of you.

You both answered the question fairly, honestly, and gave excellent advice. My hat's off to you gentlemen...

I'm not certain why you interpreted my general post as an insult and felt the need to attack it and me. I don't know your work and have nothing to say about it one way or the other. I merely related what I hear. There can be problems with a stretch. I'm sure some far exceed the best factory work and some are nothing but pure junk. I also agree there can be problems straight from the factory. I have a misfit and cracked cowl panel on my truck to prove it. In any case, I personally am still afraid of a stretch and still have the same general opinion I posted originally. That opinion still has nothing to do specifically with you or your work and hopefully you can live with it without feeling compelled to attack any further.

What I was trying to say about being certified was more along the line of the modification being okay with the DOT. like when someone puts on a tag axle I have heard that some states will not accept the extra weight because the trucks sticker says 33k. Although I mentioned welding that was not the real important part of my question. I would like to get a VN770 stretched, That would be my dream truck.

Jim,

In my experience, when a truck is altered in a way that affects the GVWR, the Co. doing the modification will install a new rating tag on the door jamb to indicate the updated gross weight capacity.

You sound like a mechanic and truck spec. specialist who knows his stuff. I appreciate that. I would like to have a conversation some time over a cold one concerning the best class 8 straight truck for my purposes.
However, I don't think stretching is safe: one is taking a tractor and turning into something else, under conditions that are hardly worthy of factory quality. And Peterbilt can put the wrong coolant level sensor in at the factory (reg. coolant vs. ELC!)
Having said that, it sounds to me that if you are installing new frame rails, inserts, etc, setting driveline pitch angle, etc. then you are 'just' transferring a single or tandem axle to a new frame. That's a complete new rig- not a stretch. A stretch in the true sense is a disaster waiting to happen. (Would you haul 10 drums of gasoline from TX. to Windsor in that, in Jan?) Not me...

Class 8 stretch may or may not be right for everyone. But if its done correctly. Can be a very reliable unit. I had a 2000 Classic that the wife and I put 835,000 miles on it. With, no problems with the stretch. Only thing you really have to watch is the type of tractor you choose. Long hood conventionals tend to be a little heavy on the steer. Toes I would let you stretch one for me. Your post was outstanding.
