For those who hardly see any dirt, the T-Rex Bilstien system is a great package. The system that has the Fox shocks is a full on " Ultimate" off road system. The on road handling is amazing. I can slide my truck through corners like a rallye car. The Bilstiens are even better on road and can handle some serious off road too. They just wont handle it for as long as the Fox. Heat is a killer to shock performance. Heat is created by the shock oil passing through the piston. As you go faster off road and take larger hits the shaft speed increases. The result is hot oil, and a slight amount of shock fade. So, the fox has more shock oil and resists fade more than the Bilstien.
As for the system you need, Call the suspension guru and tell him how you drive your truck, what you use it for, and ask Kent what he thinks. He will give you a price, and tell you what you can expect to pay for installation. 760-749-8687
Now to clear the tires. You could probably clear them with just a 2"spacer. I perfer replacing springs and shocks. Complete system is the only way to go... .
