G-Comp™ X Fabricated Upper Control Arms

These C-Comp X fabricated upper control arms are the upper arms supplied in Speedway’s “X” edition suspension kits, as well as the 54”, 56”, and 60” Universal suspension kits. They’re purpose-built for the “X” edition uprights that use C7 Corvette bolt-in hub assemblies, ensuring the geometry and mounting points match the intended system.

For improved stability and steering feel, the arms are designed with an additional 3° of caster compared to the standard G-Comp upper control arm. They’re also designed to work in conjunction with 3501100, completing the intended “X” system setup.

• Inverted ball joint
• 3° more caster
• Sold as a Pair

Fitment is intentionally specific: these arms only bolt to Speedway subframes and are only compatible with the “X” edition uprights. The design features an inverted ball joint, which helps with deeper wheel backspacing and can support a tighter turning angle—useful for wheel/tire packaging and steering clearance. Used in kits: 3502000, 3502002, 350210, 3503000, 350600, 350610.
