Re: OffRoad Designs Chrome Molly Shafts VS Moser
I can only give some an example of the strength of the moser shafts. I have a set of AMC 20 replacement shafts in my CJ-7. The shafts are from around 1990 and have the older style bearings, special order only type. It is a rear axle so there are no u-joints to let go. The shafts are of the finest quality. I have a built 350 and they take the abuse like a champ. I have roasted 33's on dry/wet pavement and not had problems. I have of course had no problems with them in mud or anywhere else. The stress that spinning a tire on pavement adds to a driveline is tremendous. You take all that power and let it slip. Then when the tire catches nearly all of the power is transmitted into the driveline. I know it isn't smart, but what is the point of a nice engine if you don't play with it. I rolled it once. I replaced the bearings, which disintigrated into dust, and that was that. Been working fine for about 2 years since the roll over. The shafts have been in the vehicle for a 12 years and have had to put up with the driving styles of 5 different owners. As I said they are rear shafts and have no u-joints. But these shafts are strong enough to take the abuse I have given them; and apparently everyone elses abuse also.
In case this helps.
The engine is a 350 4-bolt, bored .04 over. Flat Top pistons, 2.02,1.60 valves, crane cam for towing, Edelbrock Performer intake/carb. Hooker Super Comp shorty headers. A compression ratio of either 9 or 9.5 to 1.
