Fits: 4th & 5th Gen 4Runner / GX470 & GX460 / FJ Cruiser / Prado 150 (Not for Gen 3)
What It Does
Fixes that sketchy, side-to-side axle swing after a lift.
Brings your track bar (panhard bar) back to a more natural, level position.
Keeps your rig tracking straight, planted, and predictable on-road and off. Bolt-on design — no welding, no guesswork.
Standard height brackets can potentially contact frame under suspension cycle! Shorty bracket is not available for all models. All brackets on the market have the same potential!
Why It Matters
When you lift your rig, the track bar angle gets steep. That forces the axle to swing left/right instead of moving up/down — making the rear feel unstable.
The B.O.T.C.K. raises the pivot point to flatten that bar and bring your handling back to normal. Simple fix, huge difference.
Shorty vs. Regular – Pick the Right One
How to Pick the Correct B.O.T.C.K. Version
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 to find your bolt-height difference:
1.5"–2.99" → Shorty Version(or use the bottom hole on the Standard bracket)
3" or higher → Standard Version(use the top hole)
Planning to lift higher later? Go with the Standard Version — it gives you extra mounting options as your suspension height changes.
Updates You Need to Know
No more flange nuts – now standard hex nuts.
no longer need to clearance the abs tab
Washer for side bolt no longer needed.
Torque spec: 105 ft-lbs on oem bolt hole location and the rest of the bolts at 125lbs. All bolts / nuts should get blue loctite. If red. Use very little.
KDSS or non-KDSS? Doesn’t matter. Works with both.
Real Talk
Stop buying parts you don’t need — understand what it does before hitting checkout.
This kit isn’t just stronger than weld-on options — it spreads load evenly across the OEM mount instead of depending on the welds.
Designed for rigs that actually see dirt, not just mall crawlers.

Frequently Asked Questions
Shorty or Standard — which do I need?
Park on level ground. Measure from the ground to the center of your frame-side track bar bolt, then do the same for the axle-side bolt. Subtract the two numbers:
1.5" – 2.99" difference → Get the Shorty (or use the bottom hole on the Standard bracket)
3" or higher → Get the Standard (use the top hole)
Planning to lift higher later? Go Standard — it gives you extra adjustment room as your suspension height changes.
Does this work with KDSS?
Yes. Works with both KDSS and non-KDSS setups — no modifications needed either way.
Do I need to weld anything?
No welding, no cutting, no guesswork. Completely bolt-on design — if you can use a wrench, you can install this.
