This is the ultimate in high performance Race proven off-road suspension. This system will give you up to 18? of travel with a massive 1.5? lower mono balls and 1? uppers; just like the Trophy Trucks. The lower pivots are not urethane, or Delrin they are massive 1? mono balls. This kit is high end so if you are looking for the best off-road system for your A-Arm Ranger you have found it. The race kit uses our Camburg 2.25 front hubs along with Wilwood 12? rotors and their 4 piston superlite calipers. With the bigger hubs you’ll need a wheel that has a 5 on 5.5? bolt pattern with a 4.25? center-bore for 5/8? wheel studs.
