The Dr. KDSS B.O.T.C.K. (Bolt-On Track Bar Correction Kit) is a simple, brutally effective solution for restoring rear-end stability after lifting your rig. By correcting the track bar angle, this bolt-on kit eliminates side-to-side axle swing and brings your suspension geometry back to where it should be—keeping your vehicle planted, predictable, and confidence-inspiring on-road and off. No welding, no guesswork, just results.

What It Does
Axle Control: Fixes side-to-side axle movement caused by lifted suspension geometry.
Geometry Correction: Restores the track bar to a more natural, level operating angle.
Handling Stability: Keeps the rear end tracking straight and predictable on-road and off-road.
Bolt-On Design: Installs without welding or permanent modification.
Why It Matters
Lift Side Effects: Lifting steepens the track bar angle, forcing the axle to swing laterally instead of moving vertically.
Stability Loss: That movement causes an unstable, sketchy rear-end feel.
Proper Fix: The B.O.T.C.K. raises the pivot point to flatten the bar and restore proper suspension movement.
Real Results: Small change, massive improvement in handling and control.
Shorty vs. Standard Version
Measurement Required: Measure ground-to-frame-side track bar bolt height and ground-to-axle-side bolt height.
Shorty Option: 1.5"–2.99" difference, or use the bottom hole on the Standard bracket.
Standard Option: 3" or greater difference, use the top hole.
Future-Proofing: If planning to lift higher later, choose the Standard version for added adjustability.
Design & Compatibility
Load Distribution: Spreads force across the OEM mount instead of stressing welds.
Strength Advantage: Stronger and smarter than traditional weld-on solutions.
KDSS Friendly: Works with KDSS and non-KDSS vehicles.
Built to Wheel: Designed for rigs that see real trail use, not just pavement.
