Progressive Automotive’s 4-Link rear suspensions bars are made from heavy wall, seamless tubing, ensuring strength and durability. The bars are TIG welded for both structural integrity and a visually appealing appearance. All bars feature an adjustable end, allowing for easy adjustment. This feature enables you to fine-tune the suspension for alignment and pinion angle. Ride heights can be custom tailored to you taste during your installation. These suspension kits are specifically engineered to provide enhanced performance and adjustability, particularly for drag strip applications.
Specify either urethane bushings or Ride Tech R-Joints.
-Urethane Bushings Facts: Urethane bushings provide controlled movement, vibration isolation, and durability. Articulation is limited.
-R-joints: R-Joints offers low friction movement, allowing for smooth and effortless articulation and durability. This feature enhances the overall ride, performance and handling of the suspension system.
Progressive Automotive takes pride in manufacturing their products at their shop in Baltimore, Ohio, U.S.A. emphasizing their commitment to quality and craftsmanship.
