🔥 Scott’s Hot Rods 4-Bar Rear Suspension Kit – Ultimate Adjustable Suspension for Hot Rods & Customs!

Scott’s Hot Rods 4-Bar Rear Suspension Kits (M-42-14-PT) are engineered to deliver superior ride quality, handling, and adjustability for hot rods and custom builds. The equal-length parallel 4-bar setup ensures consistent suspension geometry, while the perpendicular double-adjustable panhard bar reduces lateral movement for a smooth and stable ride.

🔧 Fully adjustable without unbolting the link bars, this kit uses CNC-machined stainless steel rod ends with RH- and LH-threaded joints, allowing you to fine-tune pinion angle and setup with ease. Unlike triangulated 4-link systems, the pinion angle remains constant throughout suspension travel, ensuring predictable handling.

🔥 Includes Firestone 9000 air springs, allowing you to customize your ride height at the push of a button – perfect for show cars, performance builds, or everyday cruisers looking for maximum adjustability.

🚀 Designed for hot rods, street machines, and custom projects that demand both comfort and control!


🔹 What’s Included in the Kit?

✅ CNC-Machined 1 1/8″ x 1/4″ DOM Tubing Link & Panhard Bars – Adjustable for precise suspension tuning
✅ Perpendicular Double-Adjustable Panhard Bar – Minimizes lateral movement for increased stability
✅ CNC-Machined Stainless Steel Rod Ends – RH- & LH-threaded for easy adjustments
✅ FK Bearing Heim Joints – High-strength joints for durability & smooth articulation
✅ Firestone 9000 Airbags – Tapered air springs for fully adjustable ride height
✅ Upper Shock Crossmember – Allows you to fine-tune ride height during installation
✅ Rear-End Housing Brackets & Front Frame Brackets – Ensures secure mounting & alignment
✅ Sway Bar Included – Enhances stability & reduces body roll
✅ 5/8″ Grade 8 Hardware – Heavy-duty fasteners for maximum reliability

⚙️ Optimized for performance, adjustability, and long-term durability!

❓ Frequently Asked Questions (FAQ)

🔹 How does this suspension kit improve my ride quality?

  • The parallel 4-bar system ensures consistent rear suspension movement, while the adjustable panhard bar reduces lateral axle shift, resulting in a smoother, more controlled ride.

🔹 How do the Firestone 9000 airbags work?

  • The Firestone 9000 air springs allow you to adjust ride height for performance, comfort, or show stance, making them ideal for air ride setups that want a fully customizable experience.

🔹 Is this a direct bolt-in kit?

  • Yes! This kit bolts directly onto your rear-end housing and frame, requiring no welding or major modifications.

🔹 Does this kit include coilovers?

  • No, this kit includes Firestone 9000 airbags instead of coilovers. If you prefer coilovers, a separate kit with Aldan American coilovers is available.

🔹 What makes this kit different from a triangulated 4-link system?

  • Unlike a triangulated 4-link, this 4-bar system keeps the pinion angle stable throughout suspension travel, ensuring better control and more consistent handling.
