The one ton is a cheep way to go if about every part is bad up front. That's why I put one in a friends GMC when they first came out. Now I regret putting it in. Giving serious though of putting it back to original. I just don't see a good reason to put one in. Bob Dunahugh

I see the one ton as the only hope for the future
- can no longer buy new parts for the oem front ends
- can no longer buy oem axles
- the separate bearing packs are available and plentiful
- the 12 inch disks supply good brakes
This makes the 1 ton the ONLY hope for the future of my 3 gmcs

Roy,
The spacers are used by GM on their 1 Ton units. That is not a negative,
it's the geometry that is a concern that people who understand front end
geometry are questioning.
Bob D had several racers drive the unit with and w/o the suspension on a
track, result was that they felt it did not handle very well .

isn't it true that the axles are specifically built for the 1 ton? and you only have a couple venders that they are available from?
isn't that the same for the A-arms?
With all the coaches out there I just don't see the 1 ton as being a replacement for parts availability. If you are trying to save a buck on a total
front end rebuild, maybe it is a way to go. I still do the math in my head, and still seem to think I can replace/rebuild OEM for OEM for less then
a 1 ton kit.
It is an option, but I just can't see it as the only option as there are always trade off's.

Parts for the originals are still available, but the suppliers need to join
forces and get parts available when they get scarce.

The CV joints and boots are commonly available, as are hubs, rotors,
bearings, calipers, hoses, and ball joints. The original bearings are much
more difficult to service and change, unless you install zerks, in which
case they are only somewhat more difficult to service but still much more
difficult to replace. And if the bearing has failed, it often takes the hub
and knuckle with it, and these are hard to replace (or will be when Dave
Lenzi stops rebuilding them, which we of course hope happens later rather
than sooner).
Bearing adjustment in the original design is critically dependent on the
spacer and the machining of the hub and knuckle, and cannot be easily
evaluated after required assembly. On the one-ton, the knuckle is slightly
modified (I think it’s the upper ball-joint taper, but I may be
misremembering) but should never need replacing simply because bearing
races are not directly installed in it. The bearing is a cartridge held in
place with four bolts and can be replaced at roadside if necessary.
The lower control arm is modified, but strengthened (in the places where
early A-arms fatigue and also in the torsion-bar receptacle) and should
never need replacing short of collision damage. Bushings are unchanged from
the original.
The bearing was originally designed for the use of a spacer.
There are some handling effects, but most people don’t notice them. In
return for that, the brakes are bigger and better, and will balance
improvements in rear braking that we might make.
The handling issue is caused by the two A-arms not being exactly parallel,
which causes a small change in camber through jounce and rebound.
For me, the decision was made when I looked at just the cost of replacing
my fatigue-prone ‘73 control arms. But I was also attracted to the easily
replaced bearing and the bigger brakes.

The best example I can give of the 1 ton is on a coach that I worked on
from the Oregon Coast. The original front end was extensively worn, as was
the rear bogie top hat thrust bushings and pins, along with drum brakes,
shocks, bushings, etc.
I installed a 1 ton front end, a quadra-bag full reaction arm disc
brake system with rear sway bars, KYB gas shocks, and my wireless remote
air system.
It went from an ill handling POS that both hands on the wheel and eyes
front and center were required to keep it on a twisty 2 lane, to a real
pleasure to drive.
Money well spent, in my opinion. But, your expectations and results
may vary.

I have a complete set of OEM front end parts off my 73 if anyone wants them. Miguel did the bearings on them so they only have about 3000 miles on them before I switched to Manny’s one ton stuff several years ago. Parts are kind of rusty after being outside but still all good.

Here is my take on this. EVERY GMC still on the road is different. Yes if every suspension component on the coach is 'AS NEW"'..EVERY SUSPENSION
COMPONENT then I agree it should perform ...ah OK. I still wonder about rut wander with the difference in front and rear tracks.
My 76 Elle was a handful to drive. Manny brakes helped. True Trac helped. 2" spacers helped. Alex setting the steering up helped. 1 ton was the
final component that made everything work. The coach drove great...one hand down the road. No rut wander...good brakes...no complaints.
Yes, there was a bit of torque steer when accelerating hard from a stop but that was not a problem for me because I rarely drove it hard.
My point is that every coach has different things that are unique to it...worn bogie pins or components or whatever. No single solution exists for
EVERY GMC outside there...short of renewing the entire suspension. Do what works for you.
