- Two flat rear lift blocks

ReadyLIFT 6.0" Tall Flat Block FAQs
Does it fit an F-350?
Not on 2019-2026 models. It is listed for F-250 4WD trucks.
Is this for a 1-piece shaft?
No. It is for a 2-piece drive shaft. The 1-piece 6" version is the tapered block, 66-2760.
Will it lift exactly 6"?
Lift height varies depending on the factory block your truck has.
Can I use air bags?
No. Air bags attached to the bump stop tangs void the block warranty.
