Default Reverse leveling ideas

Hey guys. Gonna be dropping my t bars for flat angles in the next few weeks. I don't really want to get rid of the overload because I may still tow a bit. My question is how much will pulling the bottom leaf out (NOT the overload) drop me? Will it be level or will I still need to get drop shackles? My reasoning for wanting to pull a leaf is for a better ride. Knock out 2 birds with one stone.

They're already higher in the back of you drop the front it will be even more of a difference. You'll need a couple inches to level it out.

That leaf will only drop it like half an inch. You can take out the overload and a leaf and put in small drop shackles and airbags for when you want to tow. Best of everything.

Will taking the leaf out help the ride quality?

The overload removal definitely improved my ride. A single leaf should do a little bit of ride improvement.

I've got 3" drop shackles, overload removed, and use a set of Monroe Air shocks when I tow my bass boat(20' skeeter about 3,700#) and it works perfectly. The shock can take 150psi and it only take about 80psi to level the truck back out

Do you have a part number for those shocks? How good is your ride?

All it will will do is put more spring pressure on the overload. Ride will get worse if anything

MA828 is what I have. That part number includes both shocks and line kit. The ride is awesome. More like a 1500

The shocks are direct bolt in also. I've got them on two of my 1500's and they get out on my 2500 if I'm going to haul the boat somewhere

My question is how exactly? You have one less leaf which decreases your spring rate correct? Making it more like a 1500 spring (less leaves) I don't exactly get how just removing the overload will help ride much. My trucks springs don't set on the overload or anywhere near it. I'm not saying you guys are wrong at all. Just trying to see if I'm missing something here.

So you don't run them regularly? What shock do you usually run? If I did run the air shocks all the time around what pressure would you recommend?

I leave my QA1 adjustable shocks on most of the time anymore. Usually use the 1500 to tow the boat locally and use the 2500 for long trips but haven't had any for a long time. Empty, I usually leave 10-15#'s in them. Just depends on how heavy of load the rest of the time

They stay on my 1500's year around though. All they are is a standard Monroe sensatrac shock with an airbag on them.

Your thinking about this too hard. He's keeping the overload. Pulling a leaf and leaving the over load means more spring will lay on the overload which does not flex well unloaded. You reduced the spring rate of the primary stack but the travel you have before the overload starts to increase spring rate becomes much less.

Removing the overload let's the springs only work on their primary spring rate. There is no extremely stiff spring under the main pack for the springs to start layers no against and effectively start increasing spring rate till the primary springs are in full contract with the overload.

This is why trucks with worn out leafs ride like hell compared to a new set of stock leaves
