The idea behind a lift kit is that it just drops everything to keep your front end with the stock geometry. Even with a lift kit, people still crank the torsion bars to get that last couple of inches, which is no better for front end parts than stock front end with lots of crank. This is compounded with the fact that with a lift kit comes bigger tires, more aggressive driving, etc resulting in even more wear and tear on components not designed for this environment.
IMO, the best you can do with IFS lift kits is the knuckle lifts because they at least keep the steering at stock geometry and reduce the need to add more moving parts and pivot points into the system. Some don't like them due to their inherent track width increase. More times than not those same people end up putting 12.50" wide tires on the front which negates their whole argument, but I digress.
I have a lift and a rebuilt front end but will concede the only proper way to lift a GMT400 is with a solid front axle and crossover steering. This is considerably more out of pocket expense, but will be much stronger with less maintence costs in the long run.
My 2 cents.....
