I think they look a ton better, thats the main reason. The other reason is it gives a little more running ground clearance when driving.I'm going to show my ignorance here so bear with me. I'm new to the modification thing so I'm cruising a few forums to learn a little. I keep seeing the "leveling the truck" posts cropping up.
Is there any advantage to making the truck perfectly level other than cosmetic? Not trying to denigrate what you want to do to your truck, it's yours, you could paint penises all over the windows for all I care. I'm just curious to if there is any advantage to it other than that.
Toytec does offer good stuff, and good prices, but they dont offer a kit small enough to level, and their 2" kit is one spring spacer, where as cornfed will make is 2" kit into 1.5 or 1.75 if you want, and it uses 2 spacers a spring spacer and a top plate spacer, so you only loose 1" of realized droop, and your ride isnt affected with such a small spring spacer.I would also check out Toyteclifts.com and talk to Doug, he's a club member and has great quality parts and gives a club discount. Doug is also a very knowledgable guy and great to deal with.
Just another option.
Like any spacer it depends on the amount, top plate spacer are safe up to about 1.5-2", same with spring spacers.. .after that you can over extend your CV's and BJ's, cant overextend your coils, the spacer is outside the shock/spring... On a spring spacer you can acutally cause more damage to the shock, since there is more pressure on the spring when the shock fully extends, that and your ride turns to crap after about 1-1.5" of lift.i thought i read on here some where that top load spacers are bad because you can over exten your coils or something along those lines
