Hi there Mike, I had different sizes on each axle. Front was quarter inch, back was three eighths on drive and quarter inch on tag. You’re also right about not cheap, total bill, parts and labor was 1,800 dollars. I was debating if I should replace the shocks or add the MTU’s. I’m glad I went with the MTU’s. It made enough of a difference that I don’t feel the need to replace the shocks at this time. The brand I purchased are Super Steer. They used the under 30,000 units.
