The Steel Shock Fixed Discontinued 9/21 from Integra Shocks represents a direct-replacement shock absorber designed for vehicles requiring fixed, non-adjustable damping control. Built for drivers and technicians who value straightforward, reliable suspension geometry without complexity, this unit serves as a cost-effective alternative to multi-stage or electronic dampers. Fixed-rate shocks remain foundational in motorsports, trail applications, and daily-driven builds where consistent performance across varying load conditions matters more than active tuning.
Integra's steel shock construction delivers proven durability and heat dissipation under sustained driving cycles. The fixed dampening specification means internal valve stacks are calibrated to a single sweet spot—optimizing bump and rebound rates at typical street or moderate off-road speeds without electronic override. At 4.75 lbs and measuring 18 inches in length, this shock integrates into compact and mid-size platform suspension systems with minimal packaging complexity. The steel barrel and rod design resist corrosion in harsh environments while providing the structural rigidity necessary for precise suspension control and predictable body roll management.
Mechanics and enthusiasts upgrading independent rear suspension (IRS) setups benefit most from this fixed design, particularly when building budget-conscious platforms or vehicles where damping refinement is secondary to baseline durability. Installation follows standard shock replacement procedures: compress the spring, unbolt upper and lower mounts, and swap the unit. Verify wheel-well clearance and mount orientation before final torque, as shock orientation affects damping characteristics. Note this product was discontinued as of September 2021, making it suitable for inventory clearance, restoration projects, or applications where OEM specifications demand exact part compatibility.
