why would you use trailgear to keep it legal? that doenst make much sense at all
as for a 3" lift, any of the commercially made companies, that offer a 3" lift are for usually for buggies..... trucks are usually too heavy to use a 3" spring, you will want the 4" marlins they will settle a little bit and should put you right where you want it at
if you must use a 3" spring, get all-pros springs
you might think you are saving money in the long run with tg, but quality speaks for itself or marlin and all-pro
if everyone sells it for XX and one place has it for X you might think the X is a better deal, until you are let down and find out that that place was cheaper than all the competition by using underhanded sales practices and inferior products they say "are like everyone elses"
