Summit Racing SUM-G1055 | ATD 12503 1/2" Drive 20-150 ft.-lb. Torque Wrench ReviewIf you do a lot of automotive work, on single torque wrench you most likely own multiple torque wrenches for different jobs.  That goes the same for tools that one would take with them when they travel and fix things on the road.  In our case, we do a lot of traveling to ride and test items in an off-road environment.  We need tools that will hold up to traveling and still remain accurate and usable after sitting in less than ideal environments.

Our trailer is enclosed and packed with important tools that we need to use after a failure on the trail.  We are always searching for the next tool to fill the gap in what we do not have room for or do not have.  Summit Racing branded tools have been treating us well with the price and value of the tools we have received.  The tools have been brand name and the kits have offered us significant value.
