Rear Lift 1" help

I have a 2016 4x4 with a Leer shell , 6.5' bed, and 38 gal gas tank.
I did the Bilstein 5100 all around with the front shocks set at the mid position.
With the extra weight of the shell, bigger gas tank , and stuff usually in the truck bed , the rear of the truck has a slight squat and id like to raise it appx 1"

truck is used 99% on streets and freeways

Blocks? shackles? and which brand or style is best?

 

Use RAS

 

well,, that doesnt look like blocks or shackles,
and I have no idea what RAS is, ????

Does this RAS lift the rear of the truck ?

 

It will if you use the black shim

 

Due to my budget and use of the truck, I think Im going to focus on shackles.

I am looking for adjustable style that will allow me to choose between 1 and 1.5 lift.
Any brands that are better than others that are adjustable?
Also can I benefit by changing the bushings in the eyelet of the leafspring?
And I have read that sometimes you need to install spacers to change the angle of the driveshaft, any truth to that?
thanks in advance

 

If you are going for a shackle go with David @Coachbuilder1 from Ekstrom Design. https://shop-coachbuilder.myshopify.com/

I did on my tundra and I loved it. He can tell you about the spacer for the carrier bearing as well.

 

Ideally you want a raised bump stop height to preserve the spring arch with the longer shackles. Otherwise you risk flattened springs due to the longer shackles forcing the springs beyond their designed limits. Good luck!

 

My toy tech shackles squeak and it don’t hold load, it make the spring softer so it sag more with same load, that’s why I change it out and put RAS in.

 

can't say i've seen this before either but looks to be a perfect solution for towing.

 

ya thats a pretty trick wish I had seen that back in 08 when we picked this truck up

 

It's great for numerous reasons.
