The K5 Blazer received a redesign in 1973 which ran mostly unchanged until 1991. GM must've known it had a winner as they applied the old adage of, "If it ain't broke, don't fix it." While the Blazer is plenty capable in stock form, you can take yours to the next level with a variety of parts from us to make it more capable, on-road, off-road, and anywhere in between.

The Pro-Mag generates the highest current possible and precisely controls its delivery to the coil and plugs with perfect consistency.
