Whiteline 20mm Sway Bar Aluminum Lateral Lock Kit – Universal

Prevent Axial Movement on 20mm Sway Bars
The Whiteline 20mm Aluminum Lateral Lock Kit prevents axial migration of a 20mm sway bar in its mount bushings. On some applications, particularly under sustained high cornering loads, the sway bar can slide sideways in its mounts, creating asymmetric endlink geometry between left and right sides. The aluminum collar clamps to the bar and engages the bushing housing to prevent this migration.

DETAILS

• CNC-machined aluminum collar for 20mm sway bar applications
• Prevents axial bar migration under cornering load
• Universal — works with standard Whiteline mount bushing housings
• Applies to both front and rear sway bar positions
• No modification to the bar required

Axial Bar Migration — When It Occurs
Not all sway bar installations experience axial migration. The tendency is highest in high-load applications — track days, autocross, hard street driving — where sustained lateral cornering forces load the bar and its mounts for extended periods. If you’ve noticed your car handles differently in left versus right corners, or if bar migration has been observed visually, a lateral lock kit is the correct solution.

CNC-Machined Aluminum for Precision Fit
The collars are machined to precise dimensional tolerances for a snug fit on the 20mm bar diameter. They clamp securely without requiring bar modification and engage the bushing housing to resist migration in both axial directions.

Available in Multiple Sizes
Whiteline produces lateral lock kits in 20mm (KLL120), 22mm (KLL122), 24mm (KLL124), and 27mm (KLL127) to match common sway bar diameters. Select the kit that matches your bar’s diameter.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

A precision piece of hardware for sway bar installations where axial migration is a concern. Effective, lightweight, and easy to install. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
