Overview
The Rubicon Express RE1689 is a heavy-duty forged, adjustable front track bar for listed Jeep Wrangler JK and JL and Jeep Gladiator (JT) models. Its lift height range is 0 to 8 in.
Rubicon Express designed the track bar to eliminate deflection caused by oversized tires or extreme side loads. It is built from heat-treated steel and uses OE-style bushings to optimize handling and control.
Key features
- Forged, heat-treated steel construction
- Designed to limit deflection from oversized tires or extreme side loads
- Adjustable sleeved collar for axle alignment
- OE-style bushings for handling and control
- Front location; direct fit
- Lift height range of 0 to 8 in
Track bar setup and wear
A front track bar locates the axle side to side, so it governs how the front end stays centered under load. Heavier tires and a taller stance put more side force through the bar and its bushings, which is why a sturdy bar with firm bushings matters on lifted work. When the bar is adjusted, the goal is to center the axle so the steering stays neutral.
Check the bushings and pivot ends at regular service intervals. Cracked rubber, a clunk over bumps or steering that wanders can signal wear. Replacing a worn bar or bushing restores axle position, and it is worth checking the alignment afterward because the front wheels can drift out of spec.
- Look for play at the axle-end pivot
- Check bushings for cracking or tearing
- Confirm the axle is centered after any adjustment
- Recheck alignment after the first few drives
