Product Description
The OEM passenger-side fixed KDSS link is a known weak point - hit it hard enough on a drop or a rock and it bends, pushes the sway bar out of alignment, and starts stressing the KDSS strut shaft. The Dr. KDSS Billet Fixed Link replaces it with a CNC-machined 7075 aircraft-grade aluminum link that's designed to take that hit without bending. It accomplishes the same goal as rear KDSS drop spacers - allowing full rear suspension droop and keeping the KDSS strut piston in its OEM operating range - but does it in a stronger, more trail-resilient way. The recommended kit (Billet Fixed Link + Driver-Side Spacer) is the complete solution for 2010+ 4Runner owners running extended-travel rear shocks or wheeling harder than stock.
Fitment Notes
- Fits all 2010+ 4Runner's with KDSS
- KDSS drop kits - ours or any other manufacturer’s - are not designed to fix or prevent KDSS lean
- Works only with DRKDSS or Treaty Oak rear drop spacers
- Spacer dimensions must match this system ( 2” spacer)
Included
- (1) 7075 billet fixed link
- Pre-installed ¾" Pro Bearing uniball with snap ring
- (2) M10 × 1.25 × 60mm flange head bolts (clear zinc)
- (2) M10 × 1.25 locking nuts
- (2) Stainless steel high-misalignment spacers
- (2) Washers (not used on all vehicles). If you have room because you have the round bushing and thinner smaller cap. Run the washers with the locking nuts. If you have an updated bushing and bottom cap ( thicker , typically 2018+ ) then no need for washers

Product Features
- Eliminates the OEM Fixed Link Failure Point - The factory passenger-side fixed KDSS link is vulnerable to direct trail impacts; a bent link misaligns the sway bar and can damage the KDSS strut shaft. The billet 7075 link removes that weak point entirely
- Full Rear Suspension Droop - KDSS Strut Stays in OEM Range - Allows complete articulation when running extended-travel rear shocks while keeping the KDSS strut piston operating where Toyota designed it to
- Clears a 285/70/17 Spare in the Factory Location - Repositions the rear sway bar with enough clearance to run a larger spare without relocation
- Four Kit Options - Buy What Your Build Needs - Already have two good drop spacers? Grab the link only at $200 and get a $40 credit for your old spacers. Starting fresh? The $250 Billet Link + Driver-Side Spacer is the complete, upgraded setup
- Does Not Fix KDSS Lean - KDSS lean is caused by a hydraulic imbalance in the KDSS system, not sway bar position. No drop kit from any manufacturer corrects this - if you're dealing with lean, contact Dr. KDSS directly for accurate guidance before buying
