I thought this was a big no-no. But I've reviewed a few really good suspension kit co.s instructions.

Many of them add a block to the factory block. Stacked one on top of the other. Looking at a fords rear axle mounting, it deosn't seem like a big deal. (BDS)

What say the hive mind? Better to get larger one piece blocks elsewhere and use those instead?

I also noticed that BDS has an option where you can get new rear springs as part of a 4" kit that way you need no blocks. But that's big $, and that extra arch will prevent me from also using airbags for towing.

Shucks, the two inch leveling kit, and switching from f250 blocks to f350 blocks seems like a better idea anyway. No need to go crazy for just 33-35" tires.

I am not a fan of stacking blocks. I prefer longer shackles in most cases. Of course there is a limit to each...you can have too much block and too much shackle.

You should never stack blocks in the rear and you never USE blocks in the front. Yes, some companies say it's fine [stacking] but I'd rather err on the side of caution myself. I have seen some short angle blocks meant to realign the driveshaft a bit better when lifting and thats as far as I'd go if it HAD to be used due to vibration.

I've seen stacked blocks spit out on rough terrain. Stacked blocks are for Highway Queens that never get dirty.

Would you stack body lifts?

IMO suspension block stacking is even worse since you have moving unsprung parts and blocks that can "escape" even with the ubolts in place. Lastly you have many many body mounts in case one gives up. You lose one block and if going very fast you'll be in for a ride.

No I'm not advocating BL stacking. I'm just pointing out how lift blocks are no better

No added block, I would even ditch the factory block and use only lift springs.

Thanks. If I go with 4" than I'll spring for the arched No-block needed springs. I'll have to fab the braket for the airbags, but that is probally nothing some angle iron and a welder cant fix.

Neither. Cut the fenders.

Thats what I did on my Mountaineer, and my Bronco. I prefer a low CG.

Here is an example of a suspension system rather than a "lift kit"

This right here.
