Ok I need some driveshaft ideas. 08 GMC CC that's going to put down about 500 rwhp and will be bagged. My factory one is known to be a pos at speeds over 100 and requires me to channel my floor for clearence. A two piece from a 98-06 ext cab should remedy the clearance issue but will it hold up to the power?

 

99-06

 

Yup find an excab 2PC DS get some new ujoints rebalance and weld in carrier bearing case (crossmember) and you'll be good! I know Tellez MotorSports came up with special price on these installed! I'm waiting to get mine done once they do their 6spd 14B truck and make sure there's no issues. If your local in Houston or RGV I'd give them a shout.
