Alright, I put my T-Rex bilsteins on monday. Put 110 psi air in them because 1) that's what my air comp had 2) haven't had time to get nitrogen. The ride on the 99 "highway" is worse. I mean alot worse. Took the wife and she agree's. Took it to my dad's in the country over a freshly disced field of clay soil, the faster I went the better it rode, that was cool. Back home down the 99, sucked. At 70mph, it hurts you. Down the asphalt roads, it's cool. Around town, turns and speed bumps, the faster the better. But that freakin 99 highway! Today I took it up to Cedar Grove in Kings Canyon National Park. Lots of curves, I used to drive it with 2 hands, drove it with one. Handles better than my cars. Took it off road, the faster the better. Back to my dad's, put in 300lbs of tractor wheel weights for the drive home down 99. It rode better. I hope someone can give me some insight on how much difference the nitrogen will make in the shocks. Hopefully Friday I'll have time to get it done. My tires are BFG AT's 40psi front 35 rear. I wasn't expecting a BMW ride, just something better than stock on the highway. Maybe my expectations were off. I'm not bashing this product. I read all the posts before buying this, I know it was made for off-road, and in that area it blows away the old stuff. I've had this truck for 6 months, before this i've only had a Dodge Dakota, so that's what I have to compare it to. Not exactly a 3/4 ton truck. Sorry for the long post, just sharing MY experince's so far. (Flame suit on).
