Hey Guys! I am hoping someone in here can help me! I have been looking for a front leveling kit for my 08 f-450 2wd and settled on a Daystar spring spacer kit with Fox reservoir adjustable shocks in the fronts and Fox reservoir non-adjustable shocks for the rear. The mechanic I took my truck to said that the Daystar "Blocks" won't work for my truck but, these are the only blocks I have been able to find to lift my truck 2/2.5". My truck has the factory suspension and nothing has been changed. Yet, these blocks are listed to work for my application by every supplier that sells them. Any ideas why these wont work for my truck? Is there something the mechanic may overlooked? Any help or suggestions will be appreciated.
