Eibach or bilstein?
 

Anything that replaces the factory springs is the only real choice to make.

Buy the best and cry once...

I put Bilstein 6112's on the front and the 5100's on the rear. Rides better than stock by a long shot.

i have the same setup as you..but i got 2wd..quick question do u think ride with get soft with time? mine ride is very firm.

I went with Eibach because it was cheaper. The whole kit was cheaper than just the fronts of the Bilstein.

Definitely Bilsteins b8 6112

I really think you will be happy either way. Ive had both on the same truck and they both ride great.

I have Bilstein 6112's on the front and the 5100's on the rear

I disagree. I've had that mentality for quote a while and I'm done with it. Bought a swarvoski stx 65mm spotting scope because I wanted the best and not to have to buy another. Sold it 2 years later for a $1500 loss and bought a $800 vortex that suits my use better. As for suspension about 6 months ago I bought icon 2.0 smoothies and rear shocks, after being told they would be better for my needs than the boss kit. Apparently I didn't explain what I was after good enough because I am very unhappy with the ride these have a slow/normal speeds. Higher speed they are ok. Currently pricing out the eibach kit and will more than likely go that route and sell these locally. Everything has its use, so the buy once cry once doesn't really fly. Turns out I'll have cried twice from your motto

I would look into a re-valve cost for those icon's. They can make them behave almost however you want with valving and might be cheaper than replacing.
