If you are installing steering, trac bars or other suspension parts from us, most of them require reaming out the stock metric holes to larger SAE holes, these reamers are the right tool for the job.
 
Standard 1/2'' shank fits any drill.
 
Available in 5/8 or 3/4 inch hole size. (94-13 steering, trac bars and longarms need the 5/8 reamer. 14-up parts use 3/4 reamer)
