Need more rear lift

I recently had a RC 6” lift installed with Vertex C/Os.

This kit lifts the rear with 4” blocks which keeps everything level but appears to have a slight sag to it. The sagging is really evident when towing my boat. I would like to get another 2-3” in the rear to have a slight rake. I have looked at the 3+ Coachbuilder shackles (1.75”) and the OME Dakar springs (2.5”). Would you guys recommend either of these options or something else? Also would these options work with the 4” blocks?

 

Have you considered airbags?
Can't help ya with the spring/shackle combo.

 

Depends on how much you want to spend. Less $ go for the shackles. More $$ go for the new springs. If it doesn’t matter, I’d go for the springs since factory ones are soft and start to sag after awhile.

I have these. I have some rake. level when I tow my boat.

 

I just ordered a custom leaf pack from Alcan Springs. It will eliminate my 4" block. I also had them build it for 450lbs constant load. Cost me about a grand.

 

What about lowering the front coils. Saves you some coin.

 

Eliminating the block sounds like a win to me. Be sure and come back and post your impressions once you've installed.

 

Looks like springs may be the way to go. Thanks

Only place where $500 an inch makes sense. Lol

 

I have airbags on mine for towing and am very happy I did. Oh and your truck looks good!

 

Thank you
