The Koni 8745.1419L is a Special Active front left shock absorber built specifically for the 2019 and newer Toyota RAV4 XA50 platform, covering all available engine configurations. Using Koni's latest generation of patented Frequency Selective Damping (FSD) technology, the 8745.1419L automatically adapts its damping rate to road conditions in real time, delivering sharper handling and improved road holding without sacrificing ride comfort. This is a direct 1:1 bolt-in replacement for the factory strut insert, requiring no modifications to the existing suspension geometry. The 8745.1419L is the front left unit and must be installed with the front right shock 8745.1419R for a matched pair.
Why the Koni 8745.1419L Outperforms Stock
Factory shock absorbers on the Toyota RAV4 XA50 are calibrated for a broad average of drivers and road conditions. The result is a compromise that allows body roll, vague steering feedback, and gradual fade under load. The 8745.1419L uses Koni's Frequency Selective Damping technology to separate high-frequency inputs (rough pavement, small bumps) from low-frequency inputs (cornering, braking, acceleration loads). High-frequency inputs pass through with minimal resistance for a supple, comfortable ride. Low-frequency inputs are damped firmly, reducing body roll and keeping the tire planted for precise steering response.
The twin-tube gas pressure design maintains consistent oil temperature and aeration control, preventing shock fade during extended driving or spirited back-road use. Technology proven on over 10 million factory-equipped vehicles worldwide backs every Koni Special Active unit.
Koni Special Active FSD Technology
The Frequency Selective Damping system at the core of the 8745.1419L operates without driver input or electronic sensors. A passive internal valve responds to the frequency and velocity of suspension inputs, automatically stiffening for slow, large body movements while softening for fast, small road-surface inputs. The result is a shock absorber that genuinely does two jobs at once: performance handling and daily-driver comfort. No adjustments, no switches, no modes to manage.
Fitment: 2019+ Toyota RAV4 XA50
The 8745.1419L fits the Toyota RAV4 XA50 (fifth generation) built from the 2019 model year forward, spanning all available drivetrain and engine configurations including FWD, AWD, hybrid, and plug-in hybrid variants. Also fits the Suzuki Across (2020+), which shares the XA50 platform. Confirm your model year and platform code before ordering. This is a single left-side unit.

What Is Included
- 1x Koni 8745.1419L Special Active front left shock absorber
- Mounting hardware as specified by Koni for this application
Installation Overview
The 8745.1419L is a direct-fit strut replacement designed for technicians familiar with MacPherson strut service. A spring compressor is required to safely transfer the OEM coil spring to the new shock body. Professional installation is strongly recommended. Standard front strut service on the RAV4 XA50 typically requires 1.5 to 2.5 hours per side at a shop.
- Tools required: spring compressor, torque wrench, socket set, strut nut socket
- Compress and transfer factory coil spring to the new Koni strut body
- Torque all fasteners to Toyota factory specification
- A four-wheel alignment is strongly recommended after strut replacement
- Install the matching 8745.1419R on the right side for balanced handling

Frequently Asked Questions
What does the Koni 8745.1419L fit?
The 8745.1419L fits the Toyota RAV4 XA50 fifth-generation platform from the 2019 model year onward, covering all engine variants including 2.0L, 2.5L, hybrid, and plug-in hybrid. It also fits the Suzuki Across (2020+), which shares the same XA50 chassis architecture.
Do I need to buy two units for a full front replacement?
Yes. The 8745.1419L covers the front left position only. For a complete front axle upgrade, you also need the Koni 8745.1419R for the front right. Installing matched shocks on both sides is required for balanced handling.
What is Koni Frequency Selective Damping?
FSD is Koni's patented passive adaptive damping system. An internal valve reads suspension input frequency and automatically adjusts damping: soft for high-frequency road surface inputs for ride comfort, firm for low-frequency body motion inputs for handling control. No electronics or driver adjustment required.
Is a spring compressor required to install the 8745.1419L?
Yes. The 8745.1419L replaces the strut cartridge in a MacPherson-style front suspension. The factory coil spring must be safely compressed and transferred to the new unit. This job requires proper spring compressor equipment. Professional installation is recommended.
Does the 8745.1419L require a wheel alignment after installation?
Yes. Any front strut replacement on the Toyota RAV4 XA50 should be followed by a professional four-wheel alignment. Strut removal and reinstallation affects front camber and toe settings, which will alter tire wear and handling if not corrected.
Will the Koni 8745.1419L void my Toyota RAV4 factory warranty?
No. Under the federal Magnuson-Moss Warranty Act, a manufacturer cannot void your factory warranty simply because you installed an aftermarket part. The dealer or manufacturer must prove that the aftermarket part directly caused the specific failure being claimed before warranty coverage can be denied on any related component.
Is the Koni 8745.1419L compatible with RAV4 hybrid and plug-in hybrid models?
Yes. The 8745.1419L fits all powertrain variants of the Toyota RAV4 XA50, including the standard 2.5L four-cylinder, 2.5L hybrid (AXAH52/AXAH54), and 2.5L plug-in hybrid. Confirm your specific chassis code if you have any questions about your trim.
Does this product carry a Prop 65 warning?
Yes. California residents: This product contains chemicals known to the State of California to cause cancer and reproductive harm. See www.p65warnings.ca.gov.
How does the Koni Special Active compare to the factory RAV4 shocks?
The factory RAV4 XA50 shocks use a fixed-rate damping tune. The 8745.1419L uses FSD technology that automatically adjusts to real-time driving conditions, providing better body control in corners and under braking while maintaining or improving ride quality on rough surfaces.
What is the extended length of the 8745.1419L?
The Koni 8745.1419L has a maximum extended length of 604 mm, consistent with the OEM strut dimensions on the Toyota RAV4 XA50 front suspension.
