Correct rear suspension geometry and eliminate unwanted axle shift after lifting your vehicle with the Dr. KDSS B.O.T.C.K. (Bolt-On Track Bar Correction Kit) for the 2025-2026 Toyota 4Runner, Toyota Land Cruiser 250, and Lexus GX550. Designed to restore proper track bar angles, this bolt-on solution improves stability, handling, and overall suspension performance without requiring welding.
When these platforms are lifted, the rear track bar angle becomes excessive, causing the axle to move side-to-side instead of cycling naturally up and down. The B.O.T.C.K. kit corrects this by raising the pivot point, flattening the track bar angle, and restoring predictable handling both on pavement and off-road.
Features
Corrects Rear Suspension Geometry: Repositions the track bar mounting point to reduce lateral axle movement caused by lifts.
Improves Driving Stability: Helps your vehicle track straight and feel planted both on-road and off-road.
True Bolt-On Installation: No welding required, making installation straightforward for both DIY and professional installs.
Works With KDSS & Non-KDSS Models: Compatible regardless of suspension configuration.
Strength-Focused Engineering: Wrap-around bracket design distributes load across the OEM mount instead of concentrating stress on welds.
Multiple Mounting Positions: Adjustable mounting locations allow proper correction based on lift height.
Zinc-Coated Hardware: Corrosion-resistant hardware built to handle harsh environments.
Fitment
Fits:

How to Choose the Correct Version
To determine the correct configuration:
Park on level ground
Measure from the ground to the center of the frame-side track bar bolt
Measure from the ground to the center of the axle-side track bar bolt
Subtract the two measurements
Lift recommendations:
1.5"–2.99" difference: Shorty version (or bottom hole on standard bracket)
