I'm putting a 3" rear leaf block in and I've looked at all of these and they vary in price from $100 to $150. Do I need the thumb bump stop on the ReadyLift? If not, I may just get the AS but they are really only 30 bucks less. Unless they are a better product than the ReadyLift, I don't see why not get the ReadyLift. Any thoughts would be appreciated.

 

if you use your truck as a car, then no you don't need bump stops theoretically.

if you off road, tow, etc get ones with bump stops.

 

10-4, bump stops it is. Ive had 16k behind this brute. Really need a 350

 

I put on the Readylift blocks mainly for the bunp stops. But one of the other reasons I went with the Readylift over the Auto Springs was the coating. I read a few reviews that stated the AS blocks looked rusty after a few times getting wet. For me it was a no brainer for 30 bucks more.
