Sway Bar End Links and Bushings: What to Check Before Buying
A sway bar upgrade depends on the links and mounts around it. Check link dimensions, bushing size, ride height and kit contents before ordering.
It’s easy to focus on the sway bar and overlook the parts connecting it to the car. End links and mounting bushings have their own fitment requirements. If you’re replacing worn parts or planning a suspension upgrade, we’d start by identifying what is already installed and what actually needs to change.
Links and bushings are different shopping decisions
For an end link, you need the correct mounting style, bolt dimensions and usable length for its location. For a mounting bushing, the bar’s diameter is a key measurement. Whiteline specifically tells buyers to measure the sway bar rather than assume its diameter from the vehicle name. Its bushing measurement guidance illustrates why a nominally similar-looking part may be wrong.
That matters on a used vehicle. A previous owner may have changed the bar while leaving no record in the glovebox. We recommend taking photos of the current bar, brackets and link attachment points before shopping. If you can find a part number, include that too. It gives us a much better starting point than guessing from a trim badge.
Adjustable doesn’t mean universally compatible
An adjustable link works within a specified range. It still needs the right joints, fasteners and installation geometry. The Whiteline KLC110 adjustable end-link kit in our catalog is one example: Whiteline identifies KLC110 with 12 mm ball studs and a 90–115 mm length range. Those numbers are useful selection information, not permission to fit it to any car with a sway bar. See the Whiteline’s KLC110 specifications for the part details.
Our listing includes particular Nissan 350Z and Infiniti G35 applications among its fitment rows. Confirm your exact model, drive layout, axle and installed bar before ordering. If the title and fitment information leave any question, send us the details so we can check the manufacturer’s application instead of asking you to guess.
Plan the setup along with the purchase
Installing an adjustable link is more than making it reach both holes. Whiteline’s universal link fitting instructions call for neutral joint positions and advise setting adjustable links at static ride height where possible. They warn against trying to preload the bar. Use the instructions supplied for your exact kit, along with the vehicle’s workshop information.
If ride height has changed, tell the installer and tell us when you ask for parts. We would rather evaluate the setup as it sits now than recommend a stock replacement based on an old photo. Also ask who will perform the final setup. Having the right kit on the bench doesn’t complete the adjustment work.
A checklist worth keeping with your order
- Vehicle year, model, trim and drive layout.
- Front or rear location and the current sway bar part number, if known.
- Measured bar diameter when buying mounting bushings.
- Required link length, joint orientation and fastener dimensions.
- Current ride height and other suspension modifications.
- Kit quantity, included hardware and any separately required pieces.
Ask for a diagnosis before replacing parts to chase a clunk. A noise recording can help describe the problem, but it is not the same as inspecting the joints, mounts and surrounding suspension. Keep a short list of when the sound occurs—turning, braking or crossing a bump—to give the technician useful context.
Common questions
Should I buy the longest adjustable link available?
No. Buy the link that matches the application and required adjustment range. More length is not automatically more useful, and adjustment cannot correct an incompatible mounting design.
Do new end links replace the need for bushings?
No. They are separate components. Have both inspected and order the parts the actual condition and planned setup require.
What should I send you for a fitment check?
Contact us with the checklist above, clear photos and any existing part numbers. For a modified car, tell us what changed. We’ll help identify a sensible candidate before you commit to the order.
