[special-K]

Thanks for the input. All I have is real world experience as an original owner of a '92 K3500 SRW that worked every mile it was owned weighing 8,000+ pounds driven off road regularly and often towing a trailer. I cranked the torsion bars at 20,000 miles, ran 285/75s, ran it 335,000 miles and only had to replace the idler arm every 80k and nothing else. In the 22 years I ran it, everyone I talked to said it was typical of all trucks like mine to have the idler arm go bad that often when running bigger tires. It was never an issue replacing that and 80k is a lot of miles on any front end part. I don't believe you can lift a truck more with keys than with cranking torsion bars. We are talking 88-98 8-luggers here. The limiting factor is the a-arm suspension. lift keys advertise 2" lift, with one claiming up to 3". I lifted my trucks 2" with cranking and we all know if you want 4" you have to go with the drop brackets. Why would anyone spend what the 4" lifts cost if they could do the same with keys for a small fraction of that cost? It would seem you could install the keys to get the 2", then crank the bars another 2", but once again the limiting factor is the a-arm travel
