want to lower my repu!
I know I will catch some hell for this... but I dont care much for the fender gap. This is purely for aesthetics. I would love to buy a set of coilovers for the front, but I'm being cheap for now. If I can put together enough dough, I'll order a set.
does anyone have a spare set of oem front springs? cut? no more than a coil though... much more will make the ride way too harsh.
also, curious if i remove the second longest leaf in the rear, how much payload capacity do i lose? will replacing with an overslung helper improve anything?
thanks for any input.

2nd longest leaf removal, by my calculations, decreases rear spring rate from 312lb to 240lb. A 23.07% decrease in spring rate. Keep in mind 240 is still a high number for rear spring rate in any passanger car or truck.
You can try leaf helper, it does as advertised. I use Gabriel air shocks, they can take 120psi of air. Carried a dresser set, luggage, and Xmas gifts cross the state in pouring rain no prob. Just air up at gas station. Battery powered air compressor helps here. northerntool.com is where i got mine.

if i understand you correctly...
would it be reasonable to assume that if i remove the 2nd longest leaf spring, i'm reducing spring rate, but i'm also losing 23% of payload capacity as well? part of my concern is to not lose too much payload capacity by lowering the truck.
i suppose i could go with the air shocks, but i just replaced all the shocks w/ new KYBs. the ride has firmed up quite a bit but much improved.

don't know the formula
between spring rate and payload capacity.
frame stiffening, suspension stiffening, wheelbase, width, and the volume of air in tires are all part of it

Go to a local spring shop, and have the rear springs de-arched, (loses no spring rate) and have new shortened coils wound for the front.
I use these folks: www.landrumspring.com
They are local,(to Atlanta) and I have used Landrum for years, on a number of different applications... roadrace, dirt oval, paved oval, offroad, etc.
They will custom build springs for your application.
A coilover REPU would be cool, but not real practical for normal everyday use.
