2 Gear Portal | 74Weld Motorsports

THE 74WELD ULTIMATE2 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. Like all our products, this is engineered and manufactured in San Diego, Ca
