Suburban 2500 series 2WD/4WD models are the first full-size SUVs to offer the revolutionary control and handling benefits of Quadrasteer - a four-wheel steering system that provides maneuverability and on-highway control never thought possible on a full-size SUV. The rear wheels turn in the opposite direction of the front wheels, which helps the vehicle make tighter turns, such as when cornering or getting into a tight parking space. The turning diameter of 2WD models is reduced 21 percent from 44.5 feet to 35.2 feet. For 4WD models, it goes from 44.3 feet to 35 feet. :7:
 
Read an article about that recently, and quite honestly, I don't think the weight and added complication (more stuff to break) is worth the benefits. I suppose I'd feel differently if I lived/worked downtown in a big city...

The article was on the GMC extended cab p/u. Said they had to widen the rear track by almost 5 inches to make it work, requiring fender bulges on the outside of the bed that were a bit ugly... don't know if they'll do that on the SUV's or not.
 
Coming from the world of midsize / small vehicles to the Av, the added manuverability of the 4-wheel steering is appealing. But now that I've become more used to the Av, she does just fine. Still like the idea though - but it may not be worth the cost.

It is all a matter of perspective. After driving the K2500 extended cab s/b for the last 9 years/148,000 miles, the 130" wheelbase Av seems like a two seater sports car to me!
 
I looked at...but did not drive...a Denali truck with Quadrasteer...supposed to take the turning radius of a full sized truck down to that of a Saturn Sedan...WOW!!! :eek:
However, it is a 4K jump for this option alone...it will eventually make it at least optionally to all truck lines I am sure... :B:
 
Keep in mind that Quadrasteer is cable-driven, not rack and pinion. Not the most ideal solution. I can just imagine the potential alignment nightmare.

I just picture a little guy in back with a steering wheel, kinda like on the fire trucks.....
 
I would assume that rear fender buldges and clearance/side marker lights would be required for all trucks and SUVs equipped with the Quadrasteer. ?I also think I read somewhere that it was going to be a $2500 option. ?
 
Here's a photo of the 2003 Suburban 2500 with Quadrasteer.

Now that is interesting - notice the roof marker lights, generally only required for dually's - definitely a width issue with the quadrasteer. I believe that it is a $4000 option.
 
Oops! $2,500 pricing waaay off base. I recall reading an article on the Sierra Denali in which the increase in MSRP over the '01 C3 would be about $2,500. Well once again I should have done my own homework rather than rely on the author of that article. Actual increase was around $4,000. Gandolphxx and Silversport's $4,000 estimate is more realistic. According to Edmunds, which may or may not be applicable to '03 pricing, one could have ordered a 2002 Silverado Ext. Cab 4WD with option pkg NYS 4-Wheel Steering. MSRP for the NYS option is listed at a whopping, hold your breath, $5,715. Ouch.

I personally LOVE the look of the work they did on the bed... The 'fenders' look like mini dualie fenders... ?and the tail lights are off of the step-sides. (much nicer, IMO)
 
I was able to take out a Chevy Quadrasteer truck and try it in a test site. We tried going around the cones without quadrasteer on, then we tried it with quadrasteer on What a difference it makes...wow.....Of course the first question I asked was CAN I GO AS FAST AS I WANT >:D sure they said...just dont hit us!!! I even had to let off the gas a few times or I might have lost it >:D >:D >:D

I believe the quadrasteer also turns the rear wheels the opposite way at higher speeds. In other words, below 30mph or so it turns the rear wheels the opposite way the front is going, and above 30 it turns the same way. This is supposed to make it corner better at high speed because it is actually "crabbing" around corners.

GM had a test where a normal steering truck was used to pull a trailer that tended to whip. When the Denali quadrasteer pulled the same load, the trailer wouldn't whip. (Saw that last year and maybe things are different now)
 
~~~Breathing life into old threads~~~

Please help me on this. ?How much would it take to mod an '02 Z71 with quadrasteering off an '03 Suburban?

cha..ching!!!...this seems like a costly venture....you really think the Av needs the quadrasteer system pdx... :B:

Can someone explain the need for roof lights on dually trucks? ?Is it because of the extra width? ?Why lights on the roof?
My dad's Ram has the roof lights and it's not a dually...which leads me to believe this may be a cosmetic option for some....maybe there to add to that big rig front end dodge likes to boast about... :B:
 
I agree with them being primarily cosmetic. I know that on some of the trucks, you can delete them when ordering.

Dullie AV mock up. ?It's the best I could do with limited time.
AWESOME, I think I want one - actually would be easy on the 2500 - the rear axle appears to be the same as the 1 ton dually models.

The roof running lights have to do with the width of the vehicle - I believe that they are a DOT requirement - notice that the H2 has them standard.

It wouls sure make it more trail friendly. Not that I don't mind doing 11 point turns on one lane trails up on the mountain side. ;D
 
luv2boat, that dualie is just way too cool.
I wonder if the GM will try to head that way for their next change to the AV. :love:
