King Shocks 25001-243A Front 2.5 Coilovers w/Res for 10-24 Toyota 4Runner w/KDSS

Vehicle Fitment

• 2010-2024 Toyota 4Runner (5th Gen, KDSS-equipped, 4.0L V6, 4WD)
• 2010-2014 Toyota FJ Cruiser (GSJ15, 4.0L V6, 4WD)
• 2010-2023 Lexus GX460 (J150, KDSS-equipped, 4.6L V8, 4WD)

Fitment Notes

• Front coilover kit only; rear shocks use separate part numbers.
• 4Runner/GX460 applications require KDSS-equipped vehicles; does not fit non-KDSS 4Runners or GX460.
• FJ Cruiser applications are for standard 4WD front suspension (non-KDSS) with 0-2" lift.
• Designed for approximately 0-2" of front lift; extended-travel variants (25001-243A-EXT) support up to ~3" and may require aftermarket upper control arms.
• Direct bolt-on to factory front shock locations; no welding or frame cutting required when used within the specified lift range.

Features

• 2.5" diameter shock bodies with remote reservoirs for increased fluid capacity and cooler operating temperatures
• Compression adjusters (A-variant) provide on-vehicle tuning from soft street comfort to firm off-road control
• Vehicle-specific valving optimized for 4Runner, FJ Cruiser, and GX460 chassis for balanced on-road and off-road performance
• Adjustable ride height allows fine-tuning of front lift (approximately 0-2") to level stance or compensate for added accessory weight
• Increased front wheel travel compared to stock for improved articulation and traction on rough terrain
• High-flow piston design and precision shim stacks deliver consistent damping over washboards, rocks, and high-speed dirt
• Fully rebuildable and revalvable construction for long-term service life and future retuning needs
• Heavy-duty shafts, bearings, and seals engineered to handle overland loads, armor, and frequent off-road use

Product Description

The King Shocks 25001-243A coilover kit is a premium front suspension upgrade for shared Toyota and Lexus mid-size SUV platforms, including the 2010-2024 Toyota 4Runner, 2010-2014 Toyota FJ Cruiser, and 2010-2023 Lexus GX460. Built around large 2.5-inch shock bodies with remote reservoirs and external compression adjusters, these coilovers deliver significantly improved damping control, cooler operating temperatures, and increased front wheel travel compared to factory struts. The result is a more composed ride on pavement and far better control and comfort on washboard roads, rocky trails, and loaded overland routes.

Each kit is tuned specifically for these chassis and is designed to provide approximately 0-2 inches of front lift, allowing you to level the vehicle or compensate for front bumpers, winches, or armor while maintaining proper geometry. The compression adjusters let you quickly tailor ride firmness to your driving style and terrain, while the fully rebuildable design ensures long-term serviceability and the option to revalve as your build evolves. Fitment is confirmed for 2010-2024 4Runner, 2010-2014 FJ Cruiser, and 2010-2023 GX460 as outlined above; 2025 model-year applications are currently unconfirmed and should be verified against the latest manufacturer data before use.
