Why Ridetech?

The Ridetech Bolt-On 4-Link (SKU: 11037199) redefines rear suspension performance for your Tri-Five Chevy, replacing outdated leaf springs with a cutting-edge 4-link design. Unlike traditional suspensions or other aftermarket kits, this system offers:

Handling:

The 4-link geometry with R-Joint rod ends eliminates axle flex and wheel hop, providing precise rear axle positioning for enhanced stability and cornering grip that rivals modern performance cars.

Traction:

Optimized anti-squat and roll center height deliver ground-shaking traction, ideal for drag racing, autocross, or spirited street driving.

Adjustable Stance:

Lowers your vehicle 1-3 inches below stock, allowing a customizable, aggressive stance that turns heads at car shows while maintaining functionality.

Ride Quality:

When paired with Ridetech ShockWaves or Coil-Overs, the 4-Link transforms the soft, wallowing ride of stock suspensions into a crisp, controlled experience that inspires confidence.

Proven Durability:

Backed by Ridetech’s 1,000,001-mile warranty on shocks (when paired) and rigorously tested in performance driving environments, this system ensures long-lasting reliability.

No other 4-link system matches the precision, ease of installation, and performance of Ridetech’s Bolt-On 4-Link. It’s the industry-leading choice for Tri-Five owners seeking to elevate their classic Chevy to modern standards.
