A Jeep roll cage is often referred to components that attach to the factory sport bar. These are usually cross braces that help reinforce weak areas with the factory sport bar and help strengthen the overall rigidity of the Jeep while cornering. There are a large variety of cages available for different model Wranglers.
Cages for JK models: Smittybilt offers an SRC Cage for JK models that consists of heavy-duty 1020 Carbon Steel with steel tubing that has a 0.120-inch wall thickness. These types of cages are typically a direct bolt on to the factory sport bar and utilize a solid knuckle system as attachment points with grade 10 hardware. Utilizing a cage like this on your JK will offer a significant amount of protection during a roll over because it helps reinforce the weak point of the factory sport bar. Areas like the front windshield are reinforced with steel tubing running across the front. This helps support the windshield frame and prevent it from bending or caving in during a roll over.
Roll bar cage for TJ models: Poison Spyder also offers a cage reinforcement kit for the factory TJ sport bar similar to the kit from Smittybilt for JK models. This system is a fairly inexpensive solution that helps strengthen the weak points on the factory sport bar. If you’re looking for a more comprehensive level of protection, Poison Spyder also offers a full replacement roll bar cage for TJ models. The CNC bent DOM structural steel tubing used in the kit offers a tremendous improvement over the factory sport bar. The cage features several cross braces and reinforced sections that are far more superior to the factory design. Cross braces along the front windshield eliminate the possibility of having the windshield frame collapse during a roll over. In addition, the rear occupants are protected by another cross brace, along with an innovative center cross feature that fully protects front and rear occupants, while still providing a great open-cabin feel. The system is also designed to be a direct bolt on, that still works with the factory hard and soft top.
Roll bar solutions for YJ models: To help address the protection for rear passenger in YJ model Wranglers, Poison Spyder offers a rear spreader bar kit that ties into the rear bars and provides a solid cross bar platform and great overhead protection for rear passengers. In addition to the rear spreader bar kit, Poison Spyder also offers a trail cage that ties into the factory sport bar and helps reinforce the factory bar in the critical weak points discussed earlier such as the cross bars in the front.
