I didn't know JB did the zerk upgrade; I had him do three knuckle rebuilds so far and it was never offered to me as an option.
In hindsight, I do wish I had known about the Hubler option before that happened, of course, but as Jim told me that he would not install the 80 mm caliper upgrade up front, nor a disc conversion in the back because of liability concerns, I did assume that he would espouse the same policy towards the Hubler option.
Now that I am back to work, that conversation may be on the horizon.
How much is a Hubler conversion? Is it in "kit" form?
I saw a slide show and it mentioned in the bill of materials that 3" aluminum spacers were still required to equalize the width with the rear tire track; isn't there any way to extend the axles and control arms to achieve the extra width without placing extra/undue strain on the wheel hub & bearing?
Air Ride Technologies makes GM 3500 Control Arms with air bag mounts and I was wondering whether chromoly-constructed control arms would give us any better capability to adapt the 1-tom setup. If the stock 3500 is too short as I suspect, a longer setup could be developed that alters the baseline angle of the upper ball joint to compensate for the higher altitude and aspect ratio; this was done in the early days of Mustang suspension research by adding a simple billet wedge under the ball joint to cant it over so it would not bind. Since the GM coach is ten times the Mustang's weight, a wedge may not be the best implementation of a sound concept in this case - a welded wedge or modified/canted mounting position would be more practical and inherently stronger.
Does anyone know about the 3500 suspension in relation to our coach's?
Using air bags to supplement the torsion bar suspension would be an interesting experiment, especially with the option to use either single or double-adjustable (compression and rebound) integrated shock absorbers. The ride could be amazing.
