Overview
The King Shocks 2.5 PR bearing spacer, part number KST25039-003, is a universal fit part, so it is not tied to a specific make, model or year. Confirm fit for your vehicle’s year, model and trim before ordering.
King Shocks manufactures and services custom adjustable and rebuildable shock absorbers and performance racing products for utility vehicles, OEM replacement and professional racing. Its designs are field tested with top racers in competition and on an electro-magnetic shock dyno.
The dyno plays back racecourse data from common onboard automotive data acquisition systems and uses a non-contacting, infrared style transducer to monitor temperature. This lets engineers test shock behavior closer to real-world conditions than a laboratory setup alone.

Before you install a spacer
A bearing spacer sits in a load path, so its role in the assembly matters as much as its size. Before fitting any spacer, confirm the bearing type, the housing it seats in and the mating parts it touches. A part sold as universal fit still needs to be matched to the vehicle it is going into, since clearances and seating surfaces vary from one setup to another.
Inspect the surfaces the spacer contacts. Look for scoring, pitting or uneven wear that could shift alignment or cause noise once the vehicle is running. Clean the seating area and check that the spacer sits square before torquing anything down. Recheck fasteners after the first few drives, because new contact surfaces can settle slightly.
- Compare the spacer with the part it replaces
- Check seating surfaces for wear or damage
- Recheck fasteners after the first drives

Vehicle fitment
This spacer is a universal fit and is not tied to a particular make, model, year or trim. Confirm fit for your vehicle’s year, model and trim before ordering.
Because no vehicle is named, the spacer cannot be matched to a specific truck here, and universal fit does not confirm that it suits any particular application. Confirm the application with King before buying.
