Understanding the 2018 TRD Pro Fox Suspension
The 2018 Tacoma TRD Pro came equipped with Fox 2.5-inch diameter aluminum body shocks with internal bypass damping. These shocks are designed for improved off-road performance and are specific to the TRD Pro package. Unlike cheaper aftermarket options, the OEM Fox shocks are tuned specifically for the Tacoma’s weight and suspension geometry.
Unlike the standard Tacoma, the TRD Pro uses unique front coilovers and rear remote-reservoir shocks. The part numbers differ significantly from other Tacoma trims. Knowing the exact numbers helps you avoid ordering the wrong parts and ensures you maintain the factory ride quality.
Front Fox Shocks Part Numbers for 2018 Tacoma TRD Pro
The front suspension uses a coilover assembly with the shock integrated into the spring. Here are the factory part numbers for the left and right sides:
Left Front (Driver Side)
- Part Number: 48510-0C150
- Description: Shock Absorber Assembly, Front Left
Right Front (Passenger Side)
- Part Number: 48510-0C160
- Description: Shock Absorber Assembly, Front Right
These part numbers include the shock body, reservoir, and coil spring as a complete assembly. If you only need the shock insert (without the coil spring), the numbers are different, but Toyota does not sell the insert separately – you must replace the entire assembly.
Important: The front shocks for the 2018 model year differ from the 2017 and 2019 versions, so double-check the year when ordering. The 2018 uses a specific internal bypass tune that matches the truck’s springs and weight.
Rear Fox Shocks Part Numbers for 2018 Tacoma TRD Pro
The rear suspension uses remote-reservoir shocks mounted separately from the coil springs (the rear uses leaf springs). The rear shocks are not part of a coilover assembly. Here are the OEM part numbers:
Rear Left (Driver Side)
- Part Number: 48530-0C040
- Description: Shock Absorber, Rear Left
Rear Right (Passenger Side)
- Part Number: 48530-0C050
- Description: Shock Absorber, Rear Right
These are the complete rear shocks with the reservoir and hose. The reservoir is mounted to the frame, so if you need just the reservoir line or fittings, Toyota lists those as separate components. But for most replacements, you will order the full shock assembly.
Note: The rear shocks are designed for the Tacoma’s leaf spring setup. They are not interchangeable with front shocks or with other model years. Always confirm the part numbers before purchasing.
Coil Springs and Hardware
The front coil springs on the TRD Pro are specific to the Fox shocks. If you are replacing the spring, you need the following part numbers:
- Front Spring (Left & Right same): 48131-0C020
- Insulator (Upper Spring Seat): 48386-0C010
- Bump Stop: 48331-35200
For the rear, the leaf springs are shared with other Tacoma trims, but the shock hardware includes:
- Rear Shock Bushing Kit: 90930-03043
- Nut for Shock Upper Mount: 94180-61200
The bump stops and bushings are often overlooked but should be replaced if you are doing a full suspension rebuild. They are inexpensive and ensure the shocks work properly.
Where to Buy and Verify Part Numbers
The safest place to purchase genuine Toyota Fox suspension parts is a Toyota dealership parts department. You can also use online Toyota OEM parts retailers that ship to your location. Avoid third-party sellers claiming “OE equivalent” – only genuine Toyota parts have the correct tuning.
To verify part numbers:
- Check the sticker on the shock itself (if still legible).
- Use your VIN with a Toyota parts lookup tool.
- Ask a dealer parts specialist to confirm fitment.
Caution: Some online parts catalogs may show the wrong part numbers for the TRD Pro. Always cross-reference with the dealership or a trusted source. The numbers provided here come from Toyota’s official parts database for the 2018 Tacoma TRD Pro.
Compatibility Notes
- The 2018 TRD Pro Fox shocks are not direct bolt-on for other Tacoma trims. The spring rates and damping are different.
- These shocks will not fit the 2019+ TRD Pro because Toyota changed the suspension design for that model year.
- If you are upgrading a non-TRD Pro Tacoma to Fox suspension, you will need additional parts (control arms, springs, etc.) – the part numbers above are for replacement only.
- Aftermarket Fox shocks that claim to be “identical” to OEM may have slightly different valving. Stick with genuine Toyota parts for the factory experience.
Final Recommendation
For a 2018 Toyota Tacoma TRD Pro owner needing to replace or repair the Fox suspension, the correct part numbers are:
- Front Left: 48510-0C150
- Front Right: 48510-0C160
- Rear Left: 48530-0C040
- Rear Right: 48530-0C050
Order these from a Toyota dealer or trusted OEM parts supplier. Always verify with your VIN to avoid mistakes. If you’re replacing shocks, also consider new bushings and bump stops. This ensures your TRD Pro continues to deliver the off-road capability and ride quality it was designed for.
