The cage is built from Docol roll bar tubing. 

• Docol is considerably stronger than 4130 CrMo. Tensile Strength of 116,000 psi vs 95,000 psi, Yield Strength of 100,000 psi vs. 75,000 psi.
• Docol's heat-affected zone (HAZ) is much smaller, meaning much less joint embrittlement from the heat of TIG welding.
• Docol has a higher resistance to fatigue.
• Docol is much more tolerant of heavy fabrication (such as tube bending and forming).
• Docol is far more dimensionally consistent, with tube diameter variance of 0.3% vs. 10.0% in 4130 and wall thickness variance less than 1/3 that of 4130.
