According to their tech support the close ratio title only applies to some other vehicle, not the Yukon so the 3 turns lock to lock remains the same. I also ordered the U-joint steering shaft to go with the new steering gear which eliminates the rag connector.
I've gone through the GM rebuilt Steering Gear process several times, not pleasant. R&R and ship several times per vehicle till I got a good one. Then I read on here about Lares/Blue top/Red Head/now Borgeson. Finally good options!
