Raising the Coach by Changing Suspension Mounting Holes

[tomriley]

I had a shop raise my coach by moving the spring hangers/shackles to the lower holes, which effectively raises the coach about 2 inches, and makes it more level when towing with the F350 4X4. The shop put "extenders" on the shock rods to compensate for the added length. However, the shock rods bent, and one actually broke during the approximately 2-mile tow to my home from the shop. Obviously they did something incorrectly, but I am not sure what.

Has anyone had experience changing the suspension height? If so, were there problems encountered with the shocks? Should I have changed to shocks with a longer shank?

Any advice will be appreciated.
