1955-57 Chevy Car Heidts 4 Link Rear Suspension

The Heidts Triangulated 4-Link Kit is the premier choice for Tri-Five Chevy owners looking to replace their factory leaf springs with a more stable and adjustable performance setup. Unlike parallel systems, this triangulated design uses angled upper bars to center the axle, providing a cleaner installation and more room for custom modifications.

Performance and Advanced Geometry

• No Panhard Bar Required: The defining feature of this kit is its triangulated design. By angling the upper links inward, the suspension naturally centers the axle laterally. This eliminates the need for a panhard bar, reducing mechanical complexity and weight.

• Superior Lateral Stability: This configuration prevents side-to-side axle movement more effectively than leaf springs, allowing you to run tighter tire-to-fender clearances without worrying about tires rubbing during hard cornering.

• Optimized Traction: Moving to a 4-link system eliminates the "spring wrap" and wheel hop common with traditional leaf springs, ensuring your Tri-Five can efficiently put power to the ground.

• Precision Tuning: The bars feature 3/4-inch stainless steel adjusters with urethane bushings. This allows you to fine-tune your pinion angle and wheelbase with ease for perfect driveline alignment.

Engineering and Fitment

• Heavy-Duty Construction: Built from 1-1/4" x .156 wall tubing, these links are designed to handle high-horsepower street and strip applications.

• Versatile Frame Mounting: The kit includes both angled and straight chassis brackets, making it highly adaptable for both stock frames and aftermarket chassis.

• Adjustable Ride Height: Paired with 10-inch performance springs and billet coil-overs, this system gives you full control over the car's stance and the ability to soften or stiffen the ride quality as needed.

• Exhaust Clearance: Because the triangulated design removes the panhard bar, it often opens up valuable space for routing dual exhaust systems over the rear axle.

Kit Includes:

• Four Link Bars: Fully adjustable bars (Available in Plain Steel or Polished Stainless).

• Shock Package: Billet coil-overs (Available in Black, Plain Billet, or Polished).

• Springs: 10-inch performance coil-over springs.

• Brackets: A complete set of chassis brackets, axle tabs, and mounting hardware.

Available Options:

• Complete Drivetrain: Optional custom 9" rear axle housings with brackets pre-installed, high-strength axles, and Open or Positraction gear sets.

• Braking & Handling: Upgrade with a rear sway bar or high-performance rear disc brake kits.
