Skyjacker Suspension TJ403BLT 4 Inch Lift Kit with Dual Rate Long Travel Coil Springs

The Skyjacker TJ403BLT is a comprehensive 4-inch suspension lift component system featuring innovative dual rate long travel coil springs engineered for optimal off-road performance and on-road comfort. This complete kit provides everything needed to transform your vehicle's suspension capability.

Dual Rate Long Travel Coil Spring Technology:

Skyjacker's progressive variable rate coil springs utilize a distinctive 2-stage design that transitions from a softer Flex Rate to a firmer Ride Rate. The initial Flex Rate stage delivers exceptional ride comfort while allowing maximum suspension articulation during off-road travel. The secondary Ride Rate stage engages only after compression past the Flex Rate threshold, resulting in superior load handling and stability without sacrificing ride quality.

Complete Component Kit Includes:

• Front and rear pairs of dual rate long travel coil springs for balanced lift and performance
• Extended front and rear lower control link arms with pressed-in heavy-duty OEM-style vulcanized rubber bushings to correct caster angle
• Front and rear bump stop spacers that bolt between upper frame and factory bump stops to properly limit suspension travel
• Extended length front and rear sway bar end links with pre-installed HD rubber bushings for full droop articulation
• Tubular transfer case lowering kit to correct driveline angles and minimize driveshaft vibration while maintaining ground clearance
• Drop pitman arm designed to reduce drag link operating angle and restore proper alignment with the track bar
• Rear track bar lower axle mount bracket for axle recentering, improved handling, and reduced body roll
• All necessary bushings and high-grade mounting hardware

This engineered suspension system addresses all critical geometry corrections required for a proper 4-inch lift installation, ensuring optimal handling characteristics, reduced component wear, and maximum suspension articulation capability both on and off the road.
