2 GEAR CRAWLER
PORTAL

The hardcore rock crawling scene has progressed substantially in the last 5 years and everything is moving towards Portals. The 74Weld Ultimate 2 Gear Portals are purpose-built for the hardcore rock crawler who wants to build the ultimate rear steer buggy. In a situation where ground clearance, articulation, and steering angles are a must, our 2 gear portals are simply unmatched. We took our proven 2 gear portal platform and integrated a 40 spline Spidertrax unit bearing. The result is the strongest 2 gear portal on the market. We have been building portals for rock crawlers for 12 years. This product is a culmination of that experience and the final product shows. There is simply nothing that matches it in terms of quality, strength, and engineering.
