Are the front pads the same for all years of the tracker/sidekick?  I.E. if pads are listed to fit one year, will they fit all years?

Generally speeaking, up to approximately '98 or when the Gen 3 trucks rolled off the production line, the answer is yes.

The big difference in all older years are with the 4-door pads which are bigger and cannot be used on 2-door calipers.

I hope that this helps!

Just considering the 2-door models, what is the difference between the Gen 3's and the others?
