FAQ
What is the KSK105-20?The Whiteline KSK105-20 is a polyurethane bushing service kit for Whiteline 20mm front sway bars, replacing worn factory or original bushings with a longer-lasting, firmer alternative.
Is the KSK105-20 sold as a pair?Yes, the KSK105-20 kit includes both front sway bar mount bushings along with hardware and installation grease.
Will this kit fit my stock sway bar?This kit is designed specifically to service Whiteline 20mm front sway bars. It is not intended as a replacement bushing for the factory OE sway bar.
What symptoms indicate my sway bar bushings need replacement?Clunking or rattling noises over bumps, looser steering feel, and visible cracking or splitting in the rubber are common signs that sway bar bushings need replacement.
Are polyurethane bushings noisier than rubber?When properly greased during installation, polyurethane bushings run quietly. Periodic reapplication of grease is recommended to prevent squeaking over time.
Do I need an alignment after installing this kit?A front sway bar bushing service does not affect alignment angles, so a realignment is not required after installation.
What tools are needed for installation?Basic hand tools including sockets and wrenches are sufficient. A floor jack and jack stands are recommended to access the front sway bar mounts.
How long does polyurethane last compared to rubber bushings?Polyurethane resists oil, ozone and weathering far better than rubber, typically lasting significantly longer under the same driving conditions.
Does this kit include the sway bar itself?No, this is a bushing-only service kit. It includes replacement bushings, hardware and grease for an existing Whiteline 20mm front sway bar.
Install Instructions
- Raise the front of the vehicle and support securely on jack stands
- Locate the front sway bar mount brackets on the subframe
- Remove the mounting bolts and brackets securing the factory or existing bushings
- Remove the worn bushings from the sway bar
- Apply the supplied grease to the new polyurethane bushings
- Install the new bushings onto the sway bar in the same orientation
- Reinstall the mounting brackets and torque hardware to manufacturer specification
- Lower the vehicle and inspect for proper clearance and noise-free operation
