G-Comp™ X 1962-67 Chevy II Nova Front Suspension Kit

Speedway Motors' G-Comp line of Chevy II Nova suspension parts is engineered for performance, strength and value. This G-Comp front suspension kit is a complete bolt-in front subframe assembly for the 1962-67 Chevy II Nova. This Pro Touring front end is an all-new performance IFS designed around Speedway's exclusive fabricated uprights (uses C7 Corvette hubs), and engineered for optimum handling and vastly improved control. G-Comp subframe kits will turn your Chevy II Nova into a real G-machine, ready to take on the autocross, road course, or the street.

G-Comp X is designed with additional stiffness and race car like adjustability to make the most out of a caged car in autocross competition and high-performance driving. The G-Comp X front end is designed to run wider wheels and tires while maintaining adequate turning angle and reducing scrub radius, for super tight cornering!

The advantage:

• G-Comp X is an enhanced G-Comp front end with the following components:
  • Subframe features a chassis brace machined from billet aluminum
  • The billet chassis brace holds the upper shock mount
  • The upper shock mount position is adjustable, permitting use of multiple length shocks - Adjust your shocks in minutes!
  • The new upper shock mount provides clearance for springs with large wire diameter
• The G-Comp X version has an additional 3° caster over standard G-Comp arm
• Inverted ball joint on upper control arm allows use of deeper backspace wheels and tighter turning angle.
• Lower control arm has a recessed front strut to increase tire clearance
• Up to 275/35 R18 tires can be used in competition
• Kit comes with a 0.250" wall - 1-1/4" O.D. sway bar

G-Comp™ X Heavy-Duty Wheel Bearing Hub Upgrade

We’ve upgraded these kits to our G-Comp™ X Heavy Duty Wheel Bearing Hub. This patent-pending, billet-steel C7-style hub uses race-proven Wide-5 tapered roller bearings and a design that positively locks bearing preload for maximum strength, consistency, and safety under high lateral loads. It arrives assembled with ARP studs and high-quality lubricant, and its maintenance-friendly layout makes inspection and re-lubing straightforward. The result is measurably stiffer camber support that resists deflection, helps prevent brake pad knockback, and delivers a more consistent pedal feel in autocross and road-course use. 

This replaces the previous factory-style C7 hub approach used with our fabricated uprights, aligning the hub with the rest of the G-Comp X system’s race-ready intent and bringing hub manufacturing and quality control in-house at Speedway Motors. In short: stronger, stiffer, and easier to service—now included in all new G-Comp X kits.

• Only available with 5 on 4 ¾ bolt pattern (GM Pattern).
• Uses standard 3/4"-36 spline Steering input shaft U-joint.
