Truhart TH-H805-DR Drag Spec Coilover Kit for 06-11 Honda Civic

The Truhart TH-H805-DR Drag Spec Coilover Kit is purpose-built to help maximize straight-line performance by optimizing weight transfer during hard launches. Engineered specifically for drag racing applications, this coilover system features a specially tuned rear shock paired with stiff rear springs to minimize unwanted suspension compression off the line, helping put power to the pavement more efficiently.

During a typical launch, vehicle weight rapidly transfers from the front to the rear, causing the rear springs to compress aggressively and allowing the tires to momentarily break traction. The Truhart Drag Spec system addresses this with a stiffened 18 kg/mm rear spring rate that resists that compression surge, resulting in improved 60-foot times and a more controlled, consistent launch.

This kit includes rear drag-spec coilovers paired with complementary front components. Adjustable lower mounts allow ride height tuning without sacrificing shock travel, and upper camber plates are included for additional front-end alignment flexibility.

Key Features:

• Drag-tuned rear shocks matched to 18 kg/mm rear spring rate for optimal weight transfer control
• Rear coilovers only — front spring rate: 7.2 kg/mm
• Includes upper mounts and adjustable lower mounts
• Includes front camber plates for alignment adjustability
• Designed to reduce 60-foot drag times through improved launch traction
• Height adjustable via independently adjustable lower mounts

The Truhart TH-H805-DR is an excellent choice for Honda Civic drag racing builds where consistent, hard launches and improved quarter-mile performance are the priority.
