Whenever you can replace the front coil and shock with a little longer ones, you will end up with a better ride. Spacers work great, they just don't offer the 'best' ride out there.
There are a couple options when replacing the coil over. You could start out with OME, which have been around a long time. Their coil over does not offer adjust ability, nor a life time warranty, but they still make great gear.
If you wanted to step up to the next coil over. You could look at ours. We use the life time warranty Bilstein 5100's shock with our custom Eubach coils, with an adjustable collar, and you got yourself a Front coil over that will give you the exact ride height you want between 0 and 3.5 inch's. We back this component with a life time warranty for everything.
Hope that helps a little bit.
I am actually interested in the adjustable coil overs that you offer. I want to get the adjustable ones so that i can correct any issues later on, maybe if i get a heavy bumper, or if either side starts to sag for some reason. Im worried that if i adjust the front coils up to 3.5" that the ride would be too stiff for a daily driver though, what do you think, and can i just get a .5" top spacer and adjust them to 3" so i could get 3.5" lift total? If i did lift it 3.5" could i go with a 305/70/17 or would i need wheel spacers to make them fit well, not worried about a little rubbing at full lock? Does toytec make a 2.5" AAl for the rear so i could make it a level 3.5" lift? If i do the 3.5 lift will the bliesten 5125 give my ride enough down trave so its not too ruff and break stuff? And would lifting my truck 3.5" cause great concern to the CV boot and ball joint's, i only go off road for very minor things no rock climbing or sand dune jumping for me till i pay it off and can get a car for a daily driver. I would appreciate your honest opinion on all of this, thank you for your help
