Different coaches will respond differently to turns on the adjuster. Rear ride height, weight balance and resilience of the torsion bars all,play a role in determining how much ride height will change for a given number of turns on the adjuster bolt. My experience is six turns per inch is about right on average, but not for any one given coach. Be sure to only make changes after unloading the torsion bar with the proper tool and the coach securely supported by strong stands. If you just crank on the adjuster bolt you will strip it out. Also, watch carefully to make sure the adjuster does not bottom out on the top of the cross member. Some coaches will need an offset pork chop while others may get by with a longer adjuster bolt with the stock pork chops and still others will adjust properly via the stock adjuster bolt. Measure and set rear first, then safely measure and adjust the front, drive a few miles, remeasure both, safely adjust a bit more if necessary, drive a
few miles, remeasure both, etc. seems laborious but you will eventually get it right. All but two coaches coming to the GMCWS Casa de Fruta rally were low front, rear or both. Yours likely is as well. Stock ride height is critical to make your coach drive straight and true. If you want more info, download for free and read my presentation which you can find on the GMC page on my web site (http://jerrywork.com) or from the GMCWS web site.

Jerry, actually mine is high. After I did the one ton front end and the
control arms I replaced the pork chops with adjustable ones and then went
way up just so I could get it to take a set as I drove it for a while. Well,
it never came back down so it's about an inch and a half too high. Drives
great but is a bit funny looking so I'm going to drop it about an inch or so
and see how that is.


Thanks,
