1937-41 Willys with IDA or Outlaw Chassis Superide II Front Suspension

The Heidts Superide® II IFS System is a high-performance suspension solution specifically configured for 1937–1941 Willys projects utilizing an IDA or Outlaw aftermarket chassis. This kit replaces the need for generic adaptations, offering a purpose-built system that matches the strength and precision of these specialized frames.

Engineering and Performance

• Optimized for Aftermarket Chassis: This system is tailored to integrate seamlessly with the rail dimensions of IDA and Outlaw frames, ensuring the suspension geometry remains exactly as intended for high-horsepower Willys builds.

• Front-Mount Steering: By utilizing a specific spindle design, this kit features a front-mount rack and pinion. This configuration is a major advantage for Willys owners, as it provides maximum clearance in the engine bay for large engine blocks and headers.

• Alignment Security: The upper control arms utilize threaded adjusters for wheel alignment. Unlike eccentric adjusters that can move under stress, these threaded units stay locked in place, ensuring your alignment remains constant regardless of road conditions.

• Precision Handling: The Superide® II is engineered with built-in anti-dive and zero bumpsteer, providing a smooth, predictable ride even at a very low ride height.

Construction and Features

• 3-Piece Crossmember: The specialized 3-piece design facilitates an easier and more accurate installation on the chassis rails.

• Standard Performance Upgrades: This system comes standard with a power steering rack and a sway bar, delivering immediate improvements in steering effort and cornering stability.

• High-Performance Braking: Standard equipment includes 11-inch rotors paired with 4-piston Wilwood calipers, providing the serious stopping power required for performance street rods.

• Adjustable Stance: Includes billet coil-over shocks and springs. You can choose between stock or 2-inch dropped spindles to dial in the perfect stance.

Kit Includes:

• Main Crossmember: 3-piece weld-in structural unit designed for IDA/Outlaw rails.

• Control Arms: Tubular upper and lower arms with threaded adjusters.

• Spindles: Stock or 2-inch dropped units.

• Brakes: 11" rotors and 4-piston Wilwood calipers.

• Steering: Power rack and pinion (Manual available upon request).
