What shocks should I go with? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, after 50,000 miles (and especially so with less weight up front, courtesy of the LS1) the Belltech Nitrodrops are showing their age. I've never been much of a fan - the rear end bounces and bangs over stuff, and the front end takes way too long to stop again after a bump.

So, I need new shocks for my truck. For those who don't know, it's a '70 GMC, half-ton, two-wheel drive, with leaf springs in the back. It's also lowered 2.5" in front (spindles) and 4" in rear (springs). Interestingly enough, many catalogs just don't list the '67-'72 C10; but most list the '73-'87 C10. Every catalog that I've seen both in, lists the same exact part numbers for the leaf-spring '67-'72 as they do for the '73-'87 - so a shock available for either would be fine.

Here's what I've come across as available so far:
Edelbrock has the IAS shocks...$75 apiece from Jegs.
Koni has the 'Koni Special', $86 apiece from Jegs.
KYB has the GR2, the Gas-A-Just, and the Monomax, from $30 to $80 at Jegs. The GR2 appears to be what Early Classic has switched to from the Belltechs (my spindles / disc conversion / rear springs are Early Classic pieces).
Bilstein has the Heavy Duty, $60 apiece from Autozone.

Which of these is the best idea, or are there other shocks I should consider?

The GR2 is a rather soft shock. I got the Bilsteins from Autozone.

I have only heard good things about KYB. Monomax shocks are basicly one huge cylinder. I was told the width of the shock itself is actually about the size of the cylinder. As far as I know they only have monomax application for trucks too, so you could take advantage of that if you want.
I don't have them on my truck, but I drive a 99 ranger most of the time at work, which has monomax shocks all around. It was a huge difference from some monroes that were on there. I have driven the same routes so many times and its pretty pathetic that I know like every bump in every road around here. But the bumps feel smoother and the truck leans a little less into the turns.
I am gonna give them a try on my truck when it is time for some.
