The Rear Heavy Duty Adjustable Track Bar replaces the factory track bar so the axle can be centered under the vehicle after a lift or level. A stronger bar resists the flex that shows up as wander and vague steering on a lifted solid axle. Part number 77-6003 fits the 2007-2018 Jeep Wrangler.
What's Included:
| Kit components (ReadyLIFT) |
| Extra heavy duty track bar for stock to 4" lifted Jeep JK Wrangler 4x4 vehicles |
| Includes fully serviceable Currie Johnny Joints |
Wheels, tires, lift components and the alignment after installation are not included.
Features

ReadyLIFT track bars are built with heavier construction than the factory bar for lifted use.

About ReadyLIFT
ReadyLIFT Suspension started in 2006 with a practical goal: give vehicle and SUV owners more tire clearance and a better stance while keeping the ride and handling they had from the factory.
That idea began as an alternative to traditional big lift kits and has grown into a full range of leveling kits, SST lift systems, complete big lift kits, coilover systems, control arms, shocks and related suspension upgrades for popular vehicles and SUVs.
In August 2026 ReadyLIFT joined Bestop Premium Accessories Group, and the brand continues to invest in engineering, product development, manufacturing and customer support for lifted vehicles and SUVs.
