Icon's look great and are probably a perfect fit for most people. NOT as heavy duty as KING or FOX but very sexy. IMO biggest weakness is the design of the top plate. I have been contemplating these to run on my truck but 2 out of the 3 people that I know that have run these have cracked one of the top plates - one toasted his coil bucket. Great people to deal with. Currently, THEY DO NOT BUILD RACE SHOCKS - their market is to make Factory Replacements. If you run hard, think twice. If you plan on rebuilding your shocks, IIRC their kit is about 2x the cost of FOX or KING. If you want them to rebuild them, they do their rebuilding on Tuesdays so get them in accordingly. Once again, they are a smaller company and as such they are far more nimble and easier to deal with. They use a 14 inch spring which is not as common as 16" springs - but I am sure you'll be able to locate them.
KING - they are the King. Look at most top race trucks and buggies. Very good support. Very knowledgeable staff. Have LOTS of off road experience.
FOX - Very good racing shocks with the exception that they use steel in places where KING uses aluminum. Something to be mindful of if you live in a place where the local road crews think that roads are like meat and should be salted to bring out the best! Biggest problem with FOX is that the government contracts that they have been blessed with has hosed many of us with delayed deliveries that get delayed again. IIRC, these guys are the biggest and as such - don't expect much from the factory.
I personally think KINGs are probably the best shock out there and hey if you like them in a different color (I'm partial to black) they will make them in your color for another $300.
With regard to who to buy them from? Well, I have personal experience with Down South Motor Sports and SDHQ and they are both very good. (Your mileage will vary)
If I do get the kings...I'm assuming the extended travel might be a bit better for my freeway concerns? But with those and new uca's, does that mean my tires would rub at top with the extra inch down travel? And if so would I need some new front glasswork done?
Time on TW ...about three months...money spent...about $7000.00 so far. This place is getting expensive.
