I got curious and looked up rod options for the Pentastar and I found these "IRP Forged Connecting Rods" listed for the Jeep Wrangler 3.6 Pentastar. The only options I know of right now for aftermarket rods are the Carillo rods from Prodigy Performance and the maxSpeeding rods. I've never seen these before or heard of this brand.
