New Torsion bars from Manny

[jim kanomata1]

Manny made the hex section londer so it fills the A frame the full length
so that it lessens a chance of the hex sleeve in the A frame from rupturing.
I have seen several rupers of A frames on customers coach.
We are stocking Manny's units, and know it will be worth the swap.

I'd like to make some conclusions and state my situation to frame a question if I may.

I do have a Manny One ton installed in my coach. I'm not really sure it is a first generation or not. (I did have the swelling outer boots from the
grease rubber incompatibility and the regular Ball joint bolts) The HEX section in the Lower Control Arms have a strap welded onto it. I'm assuming
that is some of reinforcing you are talking about.

I bought the original torsion bars from Peter because I felt that the front end seemed pretty soft (a lot of stroke even after getting the correct
ride height) after installing the one ton.

You've installed a number of the "Huber" Torsion Bars. You've also installed a number of Manny / Huber Combination front ends. I think I'm
understanding that you are saying that you have not experienced a situation where the bar has torn out the hex section of the Lower Control Arms in a
Manny/Huber Combination.

Ken Henderson is saying his problem was because the control arm was already bad before installing the torsion bars.

I fully understand in the manufacturing business that products are constantly improved and specifications change for many reasons, and in this
situation, the improvement does not necessarily mean the original product was not suitable. I'm hoping that the original Huber bars that I have should
still be suitable for my use.

Jim is saying he has seen several ruptures on customer coach's but did not say if they are from Huber first generation bars or OEM or if they were
Manny One Tons or OEM front ends.

I do not use my coach during winter and road salt conditions and I did inspect my lower Control Arms for wear when I installed them ( I remembered
Kens problem)

While my opinion is things will be fine:

Do you think I will be OK?


Best regards
