I agree that it does depend on your priorities, and your resources are factors.
The Aluminum parts, for example, are not so easily repairable at home,
as stock or steel-based-alloy parts are, (for me).
I was changing a bad slave cylinder for the clutch when I bent the stock
tie rod by lifting or lowering the truck non-optimally; then I didn't pay the hundred+$
for a new one after I straightened the stock part with a Little bit of time
and some basic tools, with the Oxy-Acetylene torch.
Welding could be a factor or not...
I'd say that If you're on the road or off regularly and have the $ for the parts then
you could try them out and then please share your findings.
I'd still then think more so as to clear rocks and try and have a decent skid plate than if I had
parts installed that I could repair myself, (if the parts were on my Comanche).
I reallty am curious as to what the parts can do.
Personally, I Iike to upgrade and save weight when I may with parts,
and too I wonder if these Aluminum parts would Work better or just look better and save a few lbs.?.
For now they are not within my budget.
Cheers!
