Overview
The 1313033 is a 3-inch Sport S/T3 suspension system with Falcon 3.3 shocks. It fits the 2007–2018 Jeep Wrangler JK Unlimited 4-door in the Rubicon, Sahara, Sport and X trims. It is a stage 2 3-inch kit suited to city streets and trails.
The system combines the 3-inch lift, Sport flexarms and progressive SpeedBump bump stops in one package. The Sport flexarms are maintenance free. The Falcon shocks are designed to accompany the coil springs and to improve compression and rebound, with vehicle stability as the main goal. The system is designed to handle city streets and black diamond trails, and the maintenance-free Sport flexarms pair with the 3-inch lift.

Choosing a stage 2 system
A stage 2 system is typically chosen by owners who want more capability than a basic lift while still driving daily on pavement. Coil springs, flexarms, bump stops and shocks work best when considered as one setup rather than parts swapped piecemeal. Matching the shock and spring rates, and adjusting the flexarms to the new height, helps the truck stay stable on both road and trail.
Bump stops limit how far the suspension travels at full compression, so their contact is worth checking after installation on rough ground. Flexarm bushings need periodic inspection for wear, and an alignment should follow any arm service. Look for worn shock mounts, leaks and uneven tire wear. Keep wheels and tires within the sizes the system was designed around to protect the steering and driveline.
