Coil-Over Kit 70 Series Shocks

The QA1 Coil-Over Kit 70 Series Shocks delivers precision suspension tuning for vehicles requiring independent front-end geometry control and adjustable ride height. This aluminum coil-over assembly combines a 2.5-inch inner diameter spring with a 1.625-inch shock body in a clear anodized finish, offering strength and corrosion resistance in a compact, lightweight package. The kit is engineered for applications where factory suspension geometry must be modified or where custom ride quality and handling characteristics are critical to performance.

QA1's 70 Series shocks represent a mature design optimized for off-road recovery, street performance, and track-oriented vehicles where bump compliance and rebound control must work in harmony. The 1.625-inch diameter shock body is sized to balance internal oil volume with installation constraints on modern chassis. The 2.5-inch coil spring diameter allows for progressively wound spring rates without excessive package height, making the coil-over kit compatible with both lowered and elevated ride-height configurations. The clear anodized aluminum construction resists oxidation and abrasion while remaining significantly lighter than traditional steel assemblies—a critical advantage in weight-sensitive applications where unsprung mass directly affects suspension response.

This coil-over kit is intended for builders and technicians performing suspension upgrades on vehicles with independent front suspension, including modified street cars, off-road buggies, and competition vehicles. Proper installation requires understanding of suspension geometry, ride height measurement, and spring rate selection. The kit functions as a complete assembly, simplifying the integration of custom spring rates and damping characteristics while maintaining OE-equivalent or improved packaging efficiency compared to factory equipment.

QA1 manufactures suspension components for a wide range of automotive platforms, from vintage muscle cars to modern high-performance builds. Their 70 Series shock line occupies the mid-tier of their product range, positioned between entry-level dampers and purpose-built race shocks, making the coil-over kit a practical choice for serious enthusiasts who prioritize adjustability and reliability without premium race-spec pricing.
