Rubber down make a good simple lift.Racertech make a better lift,top mount,but more money both work well.I would add HIGHLIFTER springs as well on all four corners. If you put on either lift and your springs are original , you will be lucky to get back to stock height. That`s how much they would of spring sagged by now. Also the ride difference with the HL springs is huge,much better.
The rubberdown/highlifter spring kit is a great inexspensive combo............
