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!
