For Toyota 4Runner, Lexus GX & FJ Cruiser

The Dr KDSS B.O.T.C.K. (Bolt-On Trackbar Correction Kit) is designed to correct rear axle geometry after lifting your vehicle.

When suspension lifts increase the angle of the track bar (panhard bar), the rear axle begins to move side-to-side instead of straight up and down. This causes unstable handling and poor tracking both on-road and off-road.

The B.O.T.C.K. repositions the track bar pivot point, restoring a more natural, level geometry — improving stability, control, and overall driving confidence.

Built with a true bolt-on design, installation requires no welding or fabrication.

Vehicle Fitment

• Toyota Prado 150

⚠ Not compatible with 3rd Gen 4Runner

✔ Works with KDSS and Non-KDSS models

What It Does

• Corrects rear axle side-to-side movement after a suspension lift

• Restores proper track bar geometry

• Improves handling and vehicle stability

• Keeps the vehicle tracking straight on road and trail

• Bolt-on installation with no welding required

Why It Matters

When your suspension is lifted, the factory track bar angle becomes steep. This forces the rear axle to swing left and right during suspension movement instead of traveling vertically.

The B.O.T.C.K. raises the pivot point, flattening the track bar angle and restoring proper suspension motion.

The result is more predictable handling, improved stability, and better rear-end control.

Choosing the Correct Version

Step 1

Park the vehicle on level ground.

Step 2

Measure from the ground to the center of the frame-side track bar bolt.

Step 3

Measure from the ground to the center of the axle-side track bar bolt.

Step 4

Subtract the two measurements.

Results

1.5" – 2.99" difference
→ Choose the Shorty Version
(or use the bottom hole on the Standard bracket)

3" or greater difference
→ Choose the Standard Version
(use the top mounting hole)

✔ Planning to lift higher later?
Choose the Standard Version for additional adjustment options.

Built for Real Off-Road Use

Unlike weld-on solutions, the B.O.T.C.K. distributes load across the OEM mount, reducing stress on weld points while improving durability.

Designed for vehicles that actually see trail use, not just pavement.
