Just so everyone knows the part numbers of tc15xxx and dtc15xxx are no good anymore.
TS501-single adj fronts
TD501- double adj fronts
TS901-single adj rears
TD901- double adj rears.
Still have to mod the bushings.
For any of you wondering about single adjustable fronts, TheFunk cuts low 1.50's and high 1.40's and his truck launches beautifully with singles all around.
I cut a lot of low 1.50's on drag radials and double fronts and single rears
