new rear blocks 2 or 3 inch

fishbones182 · January 9, 2012

Im thinking about adding blocks to the rear. Im considering a 2 inch block to give me 3/4 inch of rake although i love the truck sitting level. I tow a 19' bay boat which is only arround 3000 lbs loaded on the trailer so its not really a heavy load. Now lets hear some opinoins on the size 2 or 3 inch blocks im personally thinking the 2 inch blocks will be sufficent and get me by.

If you like the look of a more level, i would go with 2" blocks. I went with 3" blocks on mine after my level and it has what I would call a stock looking rake. my sig shows my truck with the ready lift level at 2.25" and the 3" rear blocks.

yea im leaning to the more leveled look.

Yeah, if you're wanting it close to level, the 3" will be too tall. I have a 2" block stacked on top of my factory block, so the rake is exactly the same as factory....but it sits level when I'm pulling my pop-up camper with a 4-wheeler in the bed.

I want the 2 inch block for sure. I dont mind a little squat if i have to hook up to something heavy or carry a heavy load the toung weight on my boat lowers the truck about a half an inch when im hooked to it.

Yep, sounds like that 2" block will be perfect then!

I have a 2" block stacked on top of my factory block

Off topic a bit & no disrespect but is it safe to stack blocks? I only ask because my level kit allows me to take the front up another inch so when I do I want the rear to match.

Yes and no. You can stack blocks but i wouldn't stack more than two. Also you will want to put the smaller block on top. I wouldn't stack more than a factory block on top of a two inch block. IF you go more than that then you are weaking the system and blocks could have a tendacy to slide resulting in failure. Just my two cents.

I agree with 99% of this, the exception being that you stack the smaller block on top. The instructions for my Zone 2" kit specifically stated that the 2" block should be stacked on top of the factory block. In regards to stacking blocks, it can be done....if you don't get too crazy. In my case, it's just a 2" block on top of a 1.25" block...and the new blocks have great centering pins...and the u-bolts have great coverage, and fit nice & tight.

All that being said...if I could do it over again I would just replace the factory block with a taller block and be done with it.

I know the shop I worked with was quite comfortable using a 2" block with the factory shocks but you may want to get some opinions on using your factory shocks with 2 versus 3 inch blocks or if the 3" puts you in need of new $hock$ too!

anyone make replacement blocks for these trucks to equal a 2" block?

If you're not comfortable with stacking blocks....then a lot of guys just replace the factory block with a 3" block....which will give you 1.75" of lift. Zone Offroad and Rough Country both offer 3" block kits.

i run a 3" zone block in place of my factories and i love it. it rides high in the back when the bed is completely empty but by the time i pile in a fully loaded 75 quart yeti, hunting gear, and hook up a trailer it sits perfectly level.

Another option would be to replace your factory GMT-900 rear block with a GMT-800 rear block. They are a little taller and might be the amount of lift you are looking for.

I can't remember off the top of my head the height difference between the two though. It's just another option.

I've got 3" readylift blocks in the rear and the stock shocks work fine. Eventually I'll upgrade to Bilsteins that are made for the extra height of the 3" block.
