Billet Main Cap & Billet Brace Kit

EPR teamed up with BSW to offer a full USA made version of the tried and true billet main cap kit for the RB26.  We offer this system for both RWD & AWD versions.  Our kits have been used successfully on RB30s (Assembly built for Enjuku Racing) to your standard street/road going RB26.  All of our kits include all associated hardware included.  Cap material is made of USA grade 1045 billet steel and the brace is made of quality Moly steel that is precision ground for uniformity and precise flatness.

Our billet main cap system utilizes a main stud upgrade to an M12 stud. We offer those in conjunction with the billet main cap kit.
