The SPC FasTrax stud extenders increase guide stud clearance by 3.5 inches, allowing FasTrax gauges to clear large center hubs that can block installation. This set fits SPC FasTrax tools 91000 and 91010 and provides a simple adapter to improve fitment and ease of installation on vehicles with oversized hubs without modifying the gauge.
