As I do not haul or tow anymore with my old truck I would like to lower the rear end to level truck up a little. I'm thinking about removing the spacer blocks from between the leaf springs. Does anyone see a problem with doing this? I have already lowered the rear a little with shackles but I need about two more in inches.

Regards,
Gene

Why not just up the front end? Give the truck alittle bit for lift, and IMO, some better looks.

Sorry, but wouldn't that be a DOWNgrade, not an UPgrade?

Back in 99 my dad bought an f-250 4x4. It sat a little too high in the rear for his fifth wheel. If I remember right it had 4" blocks in the rear much like our trucks do. He went to a local wrecking yard and found some 2" blocks and changed them out(new u bolts) If I remember correctly, when loaded/pulling the fifth wheel he would get a groaning/grinding/binding sound from the rear when taking off in 1st. The dealership decided it was because of the shorter blocks and a load on the truck that caused the ends of the drive shaft in the slip yolk to bind up. He ended up having the driveshaft shortened. Seems a little extreme but the sound went away and he was happy which is what matters in the end I guess.

I need to do the same thing to fit into a required parking deck. Our rear blocks are 4 3/4" so I bought some cheap 3" blocks from Autozone and they were way too small to even sit on our trucks spring pads!

I have heard that some Ford Superduty models had factory 3" cast iron blocks that would be strong enough and give me the needed drop. I can't seem to find them though, I've found 2" SD blocks.

If anyone knows whether these 3" blocks exist please let me know.

BTW, I never tow, so lowering the rear 1 3/4" is no more change in driveshaft length or pinion angle than a heavy gooseneck trailer.

Dodge issued a TSB on this. Customers were having a problem hooking up gooseneck and 5th wheel trailers because the back of the truck was to high. So Dodge offered to lower the rear 2". Maybe someone who still works at a Dodge dealer can look it up. Or maybe someone knows where to look on the internet for TSB's. Good luck

I have 3" blocks that I'd like to replace with the stock 4.75" blocks if someone wants to trade. I have an extra vehicle I can drive for a few days while they're in shipping. I'll take a picture if you'd like to see, they're heavy duty blocks, no idea what they're off of.

The guy I bought my truck from put these in to level it instead of spacers up front and I'd rather have it higher. PM me if you're interested.

TSB for lowering rear

Found the TSB and part numbers. Requires removing Camper package springs though. I'm going to look into what this supplies and cost.

Thanks for the offer on the 3" blocks, I want to keep these though. I don't plan on it being lowered forever!
