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 .
