KDSS Rear Sway Bar Drop Kit (Upgraded Billet Fixed Link)

Upgrade your rear KDSS system the right way. This billet rear KDSS drop solution is built for drivers who actually use their suspension travel — replacing the weak OEM passenger-side fixed link with a CNC-machined 7075 billet aluminum link while retaining a properly positioned driver-side spacer. Stronger, safer, and built for real trail abuse.

Notes

• KDSS lean: This kit does NOT fix or prevent KDSS lean. Lean is caused by hydraulic imbalance within the KDSS system — not sway bar geometry, links, or spacers.
• Compatibility: KDSS-equipped vehicles only.
• Spacer requirement: Works only with DRKDSS or Treaty Oak rear drop spacers. Unknown spacer brands are not supported.
• Restock fee: A 20% restocking fee applies. Please confirm compatibility before ordering.

What it is

• Upgrade: Replaces the OEM passenger-side fixed KDSS link with a longer, stronger 7075 billet aluminum link.
• Design: Retains a spacer on the driver-side KDSS strut to maintain proper geometry.
• Purpose: Accomplishes the same goal as traditional rear KDSS drop spacers — but in a stronger, more trail-resilient way.

Why this exists

• Weak point: The OEM fixed link is a known failure point under hard trail use.
• Impact risk: Hard ledge drops or rock landings can bend the factory link.
• Misalignment: Once bent, the sway bar shifts and can stress or damage the KDSS strut shaft.
• Solution: This billet link eliminates that failure point entirely.

What it does

• Replaces: Weak OEM passenger-side KDSS link.
• Maintains: Proper sway bar position at full droop.
• Prevents: Sway bar misalignment that can damage the KDSS strut.
• Allows: Full suspension droop when running extended-travel rear shocks.
• Keeps: KDSS piston within OEM operating range.
• Clears: Up to a 285/70/17 spare tire in the factory location.

Design & materials

• Material: CNC-machined 7075 aircraft-grade billet aluminum.
• Strength: Significantly stronger than OEM steel link.
• Finish: Black anodized (only color available).
• Engineering: Overbuilt for real off-road use, not just daily driving.
• Load path: The fixed link carries the load — that’s why this component is billet.

Kit options

• Rear KDSS drop spacers (pair): $180 – Traditional spacer solution.
• Billet fixed link only: $200 – For customers already running two rear drop spacers.

Do you need this kit?

• Extended travel: Yes, if running extended-travel rear shocks.
• Hard wheeling: Yes, if you’re dropping off ledges or running aggressive terrain.
• Spare clearance: Yes, if running a 285/70/17 spare in factory location.
• Daily driver only: Probably not — and that’s completely fine.
