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.
