ReadyLIFT 4" Rear Block Kit FAQs
What is the carrier bearing spacer for?
It is included for trucks with a two-piece drive shaft. The one-piece version, 66-2024, does not have one.
Is the lift exactly 4"?
Lift height will vary depending on what factory block your truck has.
Can I add air bags?
No. Air spring or load leveling systems that attach to the bump stop tangs void the block warranties.
What else is in the box?
Two rear blocks, four 15.5" U-bolts and eight nuts and washers.
