QA1 Precision Products 5249 Adjustable Upper Trailing Arms are engineered specifically for 1964-67 GM A-Body vehicles to provide superior suspension control and adjustability. These heavy-duty trailing arms allow easy rear suspension adjustments for optimum handling and traction without requiring removal from the vehicle.

Key Features:

• Constructed from .120" wall cold rolled steel tubing for maximum strength and flex elimination
• On-car adjustable design—simply loosen jam nuts to adjust pinion angle for optimal performance
• Spherical ball assembly with Delrin bushings allows rear suspension to move more freely than stock components
• Fluted, greasable graphite/polyurethane bushings replace soft OE rubber bushings for improved durability and reduced deflection
• Sold as a pair for complete left and right side replacement

These upper trailing arms are ideal for muscle car enthusiasts and racers looking to improve rear suspension geometry, reduce wheel hop, and fine-tune traction for street or strip applications. The adjustable design eliminates the need for shims and provides precise pinion angle adjustment to optimize driveline performance.
