How much lift will a 1 3/4" spacer block for a strut give?

Amazon gives me free products to test. They just gave me a leveling kit that comes with a 2" (tapered to 1 7/8") block for the rear leaf springs and the 1 3/4" spacer for the front. Is there a rule of thumb for how much adding a spacer to the strut will give you for a lift? The description for the kit says 2" front and 3" rear but I think they have it reversed since a 2" spacer block between the axle and the leaf spring isn't going to give 3" of lift.

How thick would the front strut spacer need to be just to level the front without touching the rear? Will the 1 3/4" spacer raise the front 3"?

 

Front is approx a 2:1 ratio

1.75 puck is 3.5 inches of lift

 

Is the front 1.5" lower than the rear? I've been looking at (too many) pics to see if I want to go with that much of a lift.

 

Skip the spacer blocks. Not worth the trouble.

 

This and This. Much better options for some front lift for not much more money. Bilstein 5100’s, Eibach Pro Street just to name a few.

 

If I don't like it I can remove it. It was free so I'm not out any money.

 

Removing just causes more work and a 2nd alignment. Go with the Bilsteins. It will ride alot better and is adjustable.

 

I agree that blocks aren't ideal. Blocks on leaf springs cause issues like axle warp/ hoping. I can do the alignment myself and my truck is a southern truck so bolts are never rusted. With a 2 post lift doing the work is actually pretty simple. Part of the free stuff from Amazon is them trying to figure out what interests me. So when offered stuff for a Tundra I normally agree to review it. I have gotten some pretty bad stuff (like replacement headlights that couldn't be aligned with stock bulbs in them) to good stuff like LED fog lights with halo driving light rings.

I'm not worried about ride. I've owned this Tundra for over 5 years and have put less than 8k miles on it. I was using it to haul firewood to my mothers house about 10 miles away but I don't even do that anymore. I never use it in the winter when there's salt on the road.

It'll never get used off road. That's actually kind of sad. I started off roading with an 84 Toyota and over the years I must of had a dozen of them with lifts of all sorts of sizes and styles. At one point I had an 85 with 35" super swampers. That truck had a Camden supercharger, comp cam, and headers on a 22R engine running 5.29 gears and air lockers. Back then getting 200hp was hard without swapping to a V8.

I had thought about installing the blocks just too see what it looks like and then remove the rear blocks and machine the front ones thinner so the front is just level with the stock rear.
