i would stay away from skyjacker..

 

What do you suggest for a 4" suspension?

 

honestly 4inchs will make the 35's look really small.. id go 3.25

thats just me.

this is what i would reccomend... Honestly

there really great customer service!

im going to use the 3.25 when i go to 37's next hahah!

 

Hmm rough country looks good. I was thinking of the teraflex 3". Im so stuck haha

 

4 inch bds lift has been good to me so far... by the time i added my winch and with my top on i net about 3.5 inches of lift... rides very nice on road and flexes great off road.... for 600 bucks with shocks i am thrilled... clears 35s nice managed to rub them a coulple of times under full flex
