Drop Block Impact on Bags - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72BlckButy · 02-11-2013, 02:23 PM

I was talking with someone recently and they mentioned using a 1" block instead of a 2" block due to the increased air pressure needed to arrive at their desired ride height. I would assume that as a result you would sacrifice a lower ride height due to the increased pressure in the bag pushing the car higher.

1" Block - Would gain a lower ride height but lose a lower stationary position.
2" Block - Would lose a lower ride height but gain a lower stationary position.

This setup was on a leaf spring AOL (air over leaf) setup with sleeve bags.

What is everyone's thoughts on this?

Would you actually lose ride height to gain a lowered (stationary) stance?

I went with 1.5" blocks. I have trailing arms. I run a 15 inch wheel, and the blocks I chose kept me from having scrub line issues. I am happy all around. I think in a case like this, you have to decide if you want to lay frame, or just be low, and what you are willing to trade to get it.

That actually makes perfect sense! Just never thought about it that way! I currently have a 2" block installed along with dominator 2600 bags out back and this is my observation (but without having drove the truck yet). The ride height will be the only thing affected.
The reason is that regardless of which block you choose, you won't bottom out the bag. There is a lot of room down there. The only difference will be the ride height of the truck. The same bag at the same pressure will be at different heights (1 inch difference) between the two different blocks.

Thanks guys. Just had to put my thoughts into a post and see what other's thought about it.

I guess it's a small trade to be closer to the ground.

I use the lowering block to lower your vehicle:

Will your axle tube touch your frame (or top of your notch) air'd out?
If yes:
You use the block to affect a lower ride height.

If no:
You use the block to get you down all the way:
