Steve, who's opinion do you want? Those who have them love them. I don't have them and have no problems with wiggles, trucks passing, or rut wander. Now, when I have the toad sometimes I get a little rut wander but it is minimal. Spacers make the stance of the GMC look better.

I'm considering them. the new Michelins are a little bit softer than the old pep boys whatever's. There is a guy with a set locally for $50, but we cannot seem to get together so I can look at them...

Dan,

Ditto! Except we don't have a towd.

HOWEVER, Double Trouble does have a COMPLETELY rebuilt front end with ALL
Dave Lenzi's parts including the modified upper control arms and I run 5
degrees (yes FIVE) degrees of caster, zero camber, zero toe in/out.

It tracks like it's on rails!

Rob M.

Sir: Just a point of interest; On the trip to DuQuoin Rob and I ran together. He and I both have new front end rebuilds. He has Lindsey stuff with 5* caster with no wheel spacers and I have stock arms with offset bushings with 3.5* caster and wheel spacers and I am pulling a trailer. Rob checked the front wheel bearing temps when we stopped in Clarksville, Tn. His was 120* mine was 100*. He has Mobil one grease, I have Valvoline Molly.

I have not yet had anyone show me that the 2 " spacers do anything
negative to the bearings.
If you have loose knuckle fit it will promote rapid slop.
We have sold over200 of these and have not seen any problems unless
there was a preexisting problem.

With the front down in relationship to the rear. You have now adversely altered your caster. So I'd recommend getting the front back to the proper factory ride height. GM designed the front knuckle assembly to place the centerline of the two wheel bearing. To match the centerline of the tire. As this keeps the load equally on both bearings. You have how placed the major load over the outer wheel bearing. Thus you have created a load on a bearing that GM didn't design the assembly to handle. Yes, The bearings are large. But if the spacers are such a great idea for moving the wheels out to match the back. Don't you think GM would have designed the assembly that way in the first place. Most cars, and trucks built, don't have the front wheels aligned with the back wheels. So are all those designers wrong? Personally I'd never install wheel spacers on my GMC. But that's just my thought. Too many negative aspects for me.Bob Dunahugh78 Royale.

If you want to introduce torque steer to a coach that doesn't have it, go
ahead and install some wheel spacers. All the GMC lacks is a bit more
horsepower to turn it into a real handful of ill handling beast,
particularly on moderately steep uphills with limited traction, like my
driveway and the street to Manny T's. Been there, done, that. It is why I
am very reluctant to install spacers wider than what is needed to clear
large brake calipers. But, what the heck, I think that America is still a
free country, spend your GMC dollars how you want.

Installing the 2" spacers will allow you to install the 80mm Calipers on the front if you are using OEM GM dually 16" Steel Rims.

Everyone has opinions and preferences when it comes to wheel spacers.
They look good with the wider track and are required with the 1 TON conversion.
I notice a little torque steer when going uphill with full throttle on mine.

One question I have is if we use 17" wheels, do we still need the spacers?
I noticed that Manny's diesel coach had 17" alloy wheels.
Don't know if he had spacers on it.

Regards

GM 1 ton vehicles with 16" alloy or steel wheels from the factory are
equipped with cast iron or cast steel spacers that are identical to the
aluminum ones that Manny includes in his one ton conversion kits. His
aluminum spacers are fully machined instead of cast, and are a whole bunch
lighter than the factory ones. The geometry with the spacers is correct as
he can make it when fitted to the GMC coach. If it were me, I wouldn't mess
too much with the way he produces the kit.
Yes, if the ride height and alignment is not spot on, SOME, BUT NOT
ALL coaches will experience a bit of torque steer, particularly when
negotiating steep uphill grades. Front to rear weight distribution, as well
as more powerful engines will sometimes affect torque steer also. But, for
that matter, I have a customer with a completely rebuilt to factory specs
with the good adjustable pitman arm, new steering box and relay arm. It
has a very powerful 455 with EFI and it torque steers quite noticeably on
steep uphills like my driveway, particularly when it is wet. It is the
nature of most front drive vehicles to exhibit some torque steer. I have a
PT Dream Cruiser with the HIgh Output Turbocharged and intercooled engine.
Without traction control turned on on wet pavement and only a slight bit of
turn, if you use too much throttle, you will have a real handfull of front
wheel drive car really quick. Turbo SAAB automobiles, and MIni Coopers from
the 60's as well as VW GTI Rabbits all exhibit similar charactistics. Most
American Cars are too heavy on the front end to do much of it, but there
are some that do. I have noticed that when GMC coaches have nearly full
holding and fresh water tanks, they are a bit worse too. Your experiences
may vary.

My '81 Chevy Citation X-11 definitely had power torque steer
as did my '85 Buick Skyhawk T-Type Turbo Coupe.

Not a bad problem if you were ready for it!

A related question: What is the minimum spacer required on the one-ton rotors and calipers to fit an aluminum rim?

Mark, are you asking about a GMC motorhome fitted with a Manny 1 ton
conversion, using 16" Alcoa or American Eagle wheels? There are a bunch of
variables in your question, I am just trying to make sure I understand the
question before I attempt an answer.
