Featuring front tubular control arms, coilover conversion, and Speedtech torque arm rear suspension, this complete system brings professional-level performance without sacrificing daily drivability.
From smooth boulevard cruising to canyon carving or track laps, this allinone suspension package offers superior road feel, suspension articulation, and tuning control—engineered for builds where performance and comfort are equally important.
MODERN RIDE QUALITY, GRAND TOURING CONTROL
The GT Package creates a suspension system that soaks up road irregularities, while maintaining optimal tire contact for consistent grip and composure. The result? A compliant, poised ride with sharp handling and elegant balance.
TAILORED HANDLING VIA COILOVER CONVERSION
Includes a Chicane coilover conversion kit (typically with QA1 shocks) installed on the front tubular control arms, offering adjustable compression, rebound, and ride height—letting drivers dial in the perfect setup for street, autocross, or track use.
CHINCANE CONVERSION BRACKET
The Speedtech Chicane Conversion Bracket is a bolt-on adapter system that allows you to convert your classic GM front suspension from traditional coil springs to modern coilover shocks without major frame modifications. The Chicane brackets relocate the upper shock mount and strengthen the surrounding structure, providing the correct geometry and clearance for coilovers. This upgrade improves suspension tunability, increases wheel travel, and makes ride height and damping adjustments possible while maintaining factory control arm locations.
UPGRADED REAR TRACTION & LAUNCH CONTROL
The Speedtech torque arm rear suspension reduces wheel hop and boosts launch traction under power. Optimized geometry locks the rear end in place and smooths power delivery, whether you're cruising or hitting the quarter mile.
COMPREHENSIVE FITMENT, MINIMAL FABRICATION
An easy to install system, suspension and rear torque arm system are engineered to fit within factory frame rails. Requires no minitub except optional builds for wide tire clearance or aggressive stance.
TESTED STRENGTH, BUILT TO LAST
Utilizing high-strength steel control arms, torque arm tubing, this package is built for the rigors of spirited driving and high-power builds—ensuring long-term strength and reliability.
