RE: engine brace
mine is still good but have the dinamite engine brace in a drawer , i bash moderate and have taken it to he track a few times and its still good. it cant hurt to change it at a later date if you just got the truck and just want to run the stock brace for a gallon or so. like i said mine is 1-1/2 years old and still running the stock brace i probably will change it this year but thats after 6 gallons of fuel through the truck.
