Colton-
Thank you for your question. The Trail Master 4.0 Inch Lift Kit with Rear NGS Shocks will give your truck a tall stance. Yes it will fit your 20x10 94Rs with 33x12.50x20 depending you your back spacing. This kit requires at least 4.5 inches of back spacing. The major difference between this kit and the rancho is how it achieves the lift. The rancho moves the front dif down with the lower knuckle and the lower control arm and bracket. This will give you a substantially better ride. Remember you want your control arms as horizontal as possible.
