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, strength 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.
