When choosing a clutch it is best to take everything into consideration. How much engine power are you producing? How much does the truck weigh? These can play a major factor in clutch choice. But what a lot of people don’t look at is what kind of driving they do.
Let’s just say you have a 450hp engine that produces the same amount of torque and you want to drive it on the street mainly. Then a clutch that is rated for 500 hp would work just fine 99 percent of the time. Add different driving conditions like drag racing or autocross and kiss the 500hp rating goodbye. The point I’m trying to make is that the clutch can only do so much until it starts getting overworked. Toss in improper break-in time and some abuse and you better be really good at pulling the transmission.
Today’s tires are also made with better tread pattern design and stickier compounds that help the vehicle stick to the road. What that means is that the clutch now works harder to not slip under normal driving conditions and especially while goofing around with the truck. Add an adjustable four-bar or something of that nature and grip to the tires can be greatly increased.
