(yes there’s 4 links solutions)... So I would like some pictures of 3/5 drops or 4/6 drops of square bodies with leaf springs ! I would like to know how you accomplished a 5 or 6 in with the amount of leafs. I know most will be spindles, springs and flip kits, but what many forget to mention is how thick of a leaf pack they are running. Also what flip kits do you guys Like? Bell tech, western chassis, cpp, DJM, mcgaughys etc.. i feel like they are all mostly the same but is interesting how some flip kits like DJM will be confident they will give a 5in drop with no c notch while some flip kit sellers will say 6-7 and sell you or recommend you a c notch ... hope I can get some pictures of people willing to share. Maybe not since this has been done many times lol
Drops vary on flip kits because of the quantity of leafs & the thickness of each one. It's not a mystery, it's math.

In the original installed form, the rear axle tube/housing sits under the leaf pack. When doing a flip kit, the axle tube/housing is now moved above the spring pack. You take the total height/thickness of the spring pack & add in the radius of the axle tube (3" OD tube = 1.5 radius) & that's the amount of drop the truck will get (approximate).

Trucks w/fewer leafs don't drop as much as trucks w/HD leaf packs. The only thing that alters this is if the main leafs start getting pulled from the pack. When people do this, the truck can squat more because the overall capacity (or spring rate) is reduced.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
