ReadyLIFT 4" Rear Block Kit FAQs
Does it fit dually trucks?
No. It fits single rear wheel trucks only.
Can I use air bags with these blocks?
No. Air spring or load leveling kits that attach to the bump stop tangs void the block warranty and can cause the tang to fail.
Which drive shaft is it for?
A one-piece drive shaft. A two-piece version for these years is sold separately as 66-2294.
Do I need an alignment?
ReadyLIFT recommends an alignment and headlamp aim check after installation.
