Rear 4-Link Triangulated No Shocks

The QA1 Rear 4-Link Triangulated No Shocks suspension system is designed for serious drag racers, street-strip vehicles, and high-performance applications where precise rear axle control is essential. This innovative design eliminates traditional shock mounts, allowing builders to implement custom damping solutions or a shock-free setup tailored to their specific power levels and launch characteristics.

Engineered with dual diagonal support bars, this triangulated architecture resists lateral axle movement and prevents housing deflection under load. The no-shocks design allows the lower trailing arms and upper control arms to work together to manage wheel hop and squat without damper interference, providing flexibility in damping tuning or enabling a purely mechanical setup for weight-sensitive competition. This assembly mounts at standard pinion locations, maintaining consistent pinion angle throughout suspension travel, which is critical for preventing driveline binding.

Ideal for dedicated bracket racers and street cars that require repeatable 60-foot performance, this rear 4-link system is commonly favored in NHRA Stock/Super Stock classes. The triangulated design ensures the geometric stability necessary for consistent traction off the line, making it a valuable addition for those looking to enhance their vehicle's performance on the track.
