The Reliabolt but only better May 5, 2017
Reviewer: George Hettinger from Perry, Iowa USA  
The reliabolt has been our go to bolt for most of our higher line builds.  We were really excited that the XPB Bolt was now offered.  I think this will replace the reliabolt with the DLC coating in the XPB Bolt. Thanks again SRC.

Extreme Performance Bolt March 30, 2017
Reviewer: Lee Waller from Enterprise, AL United States  
Shipped fast and arrived as advertised!  Purchased as a spare but don't really think I will ever need to use it in my XPB Carrier Group.  I am thinking about using it in another BCG.  Quality parts!!  Very pleased!!
