For those that wrote in saying their wife works at Toyota and lifting any 2018 with Radar cruise and the accident avoidance features cause all sorts of havoc on the system......I have a few choice words for you, lol. Really, I just did the same RC 3" lift on mine ( Spacer front with both 3/8 leveling plates installed and rear blocks) and it has ZERO ill effect to the truck. It works perfectly and all the features work as designed. Don't believe any garbage about the 2018 not being able to be lifted, it's hogwash! There are no ck eng lights or any other warning lights! It works great and the ride is just as good as before lift. And, 20x9 Moto Metal 970 with +18 offset works perfectly also with 305/55 R20 Toyo Open Country AT II Extremes. I removed the two tiny front of front wheel mud flaps only. Go ahead and buy that 2018! You'll love it! Mine is a TRD Double Cab and it sits up there pretty good! So satisfied with this set up!
