Customers wonder, what is the difference between lift kits for 4th and 5th gen 4Runners if the shocks length are the same.
We highly recommend getting the proper spring rates and length for both 4Runners. The 2003-2009 4Runner will use a 112-620 spring which provides the particular vehicle 3 inches of font lift.
2010+ 4Runner will get a 521-600 spring which will provide 2.5 inches of lift on this particular 4Runner and if we add the top plate spacer will be the full 3” on a 5th Gen 4Runner.
If you use a 521-600 spring on the 2004 4Runner will get over 3 inches of front lift and will cause severe damage to some front end components for excessive lift amount.
