Spacers are for mall crawlers with 21'' chromed wheels and low profile tires. They are not made to go offroad and they make trucks ride like crap. So now your new vehicule that you spent a lot of money on will ride like an old beatup 4runner.

If you offroad with spacers what will happen is the oem shocks are not meant to travel the added distance that the spacers now add and they will wear out in no time.

You can get Bilstein 5100 for under $400 for the four corners. The 5100 ride really good and they will even lower the front dip when braking.

Sorry I sound maybe aggresive and ultimately it's your money, it's just I have a lot of friends who always take these bad decision and I'm taking it out on you this morning...
