QA1 R356-170 Rear Four Link Suspension System 67-69 GM F-Body MOD Series

The QA1 R356-170 is a complete rear four-link suspension conversion system designed specifically for 1967-69 GM F-Body vehicles (Camaro and Firebird). This comprehensive kit replaces the factory leaf spring setup with a modern triangulated 4-link suspension and MOD Series double-adjustable coilovers, dramatically improving ride quality, handling performance, and stance adjustability.

Key Features:

• MOD Series double-adjustable coilover shocks with 170 lb/in spring rate for superior performance and tunability
• Triangulated 4-link design with tubular links and spherical bearing bushings for precise suspension geometry
• +2 to -3 inches of ride height adjustability to dial in your perfect stance
• Designed to accommodate wider wheels and tires: up to 11-inch-wide wheels on '67-'68 models and 12-inch-wide wheels with 335 tires on '69 models
• Compatible with both standard rear end configurations and mini-tub applications
• Black powder-coated finish for durability and clean appearance
• Complete kit includes all necessary hardware and mounting components

This suspension upgrade eliminates the limitations of leaf springs, providing instant center adjustability and the ability to fine-tune ride height, ride quality, and handling characteristics. Installation requires some welding for the rear crossmember. Rear axle assembly sold separately—requires Ford 9-inch third member with 31-spline axles.
