Re: [DML] Re: Driver Side Torsion Unit

[Daniel Plakosh <dplakosh2@xxxxxxxxx>]

Hmm. Has anybody had metallurgical failure analysis performed on a statistically significant set of failed hinges to determine the cause of  the failures?  Has anybody had the hinges evaluated to determine their load limits? Do you know if any of the failed hinges ever had an over torqued torsion bar? Do you know the differences in pressure between Heningers product and the original design?  How much stronger is Heningers torsion bar ? 1%, 5%, 10%, ?%    I assume that these are all rhetorical questions. My point is : Why make the statement about someones product without the facts to backup the claims?  Believing and knowing are two different things!

I don't specifically, but after seeing cracked hinges I don't believe a stronger bar is a good thing. Also more pressure on one and and less on the other will change how the door fits as it closes. 

To take it to an extreme, why not turn the bar up so hot you can eliminate the strut (i.e. just use a shock absorber) altogether?
