The Rancho RS999907 is a QuickLIFT loaded front left strut assembly engineered for 1995 to 2004 Toyota Tacoma 4WD and PreRunner (2WD/RWD) trucks. Delivering a 1.75-inch front lift, the RS999907 arrives as a fully pre-assembled coilover unit complete with a coil spring and upper mount, eliminating the need for a spring compressor during installation. The twin-tube, gas-charged design pairs with Rancho's RS9000XL 9-position adjustable damping so drivers can dial in ride quality from a firm off-road tune to a comfortable daily setting without removing the strut.
Traditional strut replacement requires disassembling factory components and compressing the coil spring, a process that demands specialized tools and carries real safety risk. The RS999907 removes those steps entirely. Every component arrives pre-assembled and pre-set to Rancho's recommended ride height, so installation is a straightforward bolt-on process. Once installed, the RS9000XL adjuster knob on the strut body lets the driver rotate through nine distinct damping positions, tuning the front suspension response for highway cruising, loaded towing, or rock-crawling without any tools.
The 1.75-inch lift provided by the RS999907 creates clearance for larger tires while improving approach angles and front-end stance. Extended length is 18.75 inches, compressed length is 14.11 inches, and total travel is 4.64 inches, keeping the front suspension geometry within a safe operating range for lifted Tacoma applications.
The RS9000XL technology built into the RS999907 uses a simple external adjuster to move between nine damping positions. Position 1 provides the softest, most compliant setting suited to on-road driving with a loaded bed. Position 9 delivers maximum damping resistance for high-speed off-road use where body roll and wheel hop control are critical. Intermediate positions give a broad tuning range between those extremes. The adjuster is accessible without lifting the vehicle, so changing the setting between a highway trip and a trail run takes seconds.
The RS999907 uses a twin-tube shock body with a nitrogen gas charge to maintain consistent oil aeration control under repeated compression cycles. The coil spring is matched to the Tacoma's front weight bias and the 1.75-inch lift specification. The upper strut mount is pre-installed, ready to bolt directly to the Tacoma's upper strut tower. All hardware interfaces are engineered to OEM mounting locations, requiring no drilling, cutting, or fabrication.
Note: This listing is for the left (driver) side strut only. For a complete front strut replacement, pair the RS999907 with the RS999908 (right side). Struts should always be replaced in axle pairs.
The RS999907 is designed for the following Toyota Tacoma applications. The 4WD configuration applies to all model years 1995 through 2004. The PreRunner (2WD/RWD) configuration applies to model years 1998 through 2004. All trim levels are compatible. This part does not fit Tacoma 2WD non-PreRunner (standard 2WD) models.

Does the RS999907 fit my 1997 Toyota Tacoma 4WD?
Yes. The RS999907 is fully compatible with the 1997 Toyota Tacoma 4WD in all trim levels. It covers all 4WD Tacoma trucks from 1995 through 2004.
Does the RS999907 fit a Toyota Tacoma PreRunner?
Yes, but only for PreRunner (2WD/RWD) model years 1998 through 2004. The PreRunner was not introduced until the 1998 model year, so the RS999907 does not apply to PreRunner trucks before 1998. It does not fit standard 2WD Tacoma models that are not designated PreRunner.
Do I need a spring compressor to install the RS999907?
No. The RS999907 ships fully pre-assembled with the coil spring and upper mount already installed on the strut body. No spring compressor is needed, which is one of the primary advantages of the QuickLIFT design over purchasing struts and springs separately.
What does the RS9000XL adjuster on the RS999907 do?
The RS9000XL adjuster is an external knob built into the strut body. It moves the internal valving through nine distinct positions, ranging from soft and compliant for on-road use to firm and controlled for off-road use. Adjustments can be made by hand in seconds without removing the strut or lifting the vehicle.
How much lift does the RS999907 provide?
The RS999907 provides approximately 1.75 inches of front lift over the stock ride height. Actual lift may vary slightly depending on the specific Tacoma's condition, loaded weight, and any other lift components installed.
Is the RS999907 sold as a pair?
No. This listing covers the left (driver) side strut only. The right (passenger) side equivalent is the RS999908. For a complete front strut replacement, both the RS999907 and RS999908 should be purchased and installed together, as Rancho and most alignment technicians recommend replacing struts in axle pairs.
What is the warranty on the RS999907?
Rancho backs the RS999907 with a Limited Lifetime Warranty against defects in materials and workmanship. This warranty is intended for the original purchaser. Under the Magnuson-Moss Warranty Act, this aftermarket part will not void your vehicle's factory warranty simply by being installed, provided the part is not demonstrated to be the direct cause of a failure in another covered component.
Will the RS999907 fit a 2003 Tacoma with a 2-inch body lift?
The RS999907 is designed for the factory unibody and frame mounting points on the 2003 Toyota Tacoma 4WD and PreRunner. A body lift does not alter the suspension mounting locations, so the RS999907 will still fit correctly in terms of strut tower and lower control arm attachment. Always verify combined lift configurations with an alignment shop before finalizing a build.
Does the RS999907 require an alignment after installation?
Yes. Any change to front strut height or geometry will alter the vehicle's caster and camber. A professional wheel alignment is strongly recommended after installing the RS999907 to ensure proper tire wear and safe handling.
Can the RS999907 be used with a leveling kit or additional spacer?
The RS999907 already incorporates a 1.75-inch lift via the coil spring. Adding a strut spacer or top hat spacer on top of the RS999907 is not recommended and may exceed safe suspension geometry limits, cause premature wear, or void the Rancho Limited Lifetime Warranty. If additional lift is desired, consult Rancho's full lift kit lineup.
