I bought my Blaze with a lift already installed. Blocks in the back and taller leafs in the front. I know this just from looking at stock vehicles from the same year. My questions is...how do I know how much lift I have? Any way to measure or tell who manufactured the front replacement leafs? Should I ditch the blocks in the rear and go with taller leafs instead? I'm 75% on-road and 20% off-road (5% in the garage).
