Genuine OEM Nissan Drive Pinion Bearing Spacer – R200 Differential – 46.80mm – 38165-10V01
Maintain precise differential pinion bearing setup with the Genuine OEM Nissan Drive Pinion Bearing Spacer – 38165-10V01, a factory replacement precision spacer specified for selected Nissan R200 rear differential assemblies.
This genuine Nissan component is identified as a 46.80 mm drive pinion bearing spacer, intended for applications requiring this particular selective-fit spacer specification.
During differential assembly and rebuilding, the relationship between the pinion bearings, spacer and associated adjustment components is critical to correct bearing operation.
The pinion bearing spacer forms part of the assembly that establishes and maintains the required bearing arrangement. Its selected length must be appropriate for the particular differential, bearings and factory setup procedure.
Incorrect spacer selection can result in excessive or insufficient pinion bearing preload, potentially causing abnormal bearing wear, overheating, differential noise or premature component failure.
Whether you're rebuilding a Skyline GT-R rear differential, replacing worn pinion bearings or restoring a compatible Nissan final drive assembly, using the correctly specified genuine Nissan spacer is important for achieving the intended factory setup.
Important: This is a 46.80 mm selective-fit spacer. It must not be selected based on vehicle model or R200 differential identification alone. The required specification must be established using the applicable Nissan workshop procedure.

Important Fitment Information: The vehicle list above represents potential applications only. It does not mean every model, production year, drivetrain or differential variant uses this spacer.
Even where the differential assembly is compatible with the 38165-10V01 spacer family, the 46.80 mm length may not be the correct selection for the particular differential being rebuilt.
Different spacer lengths may be required depending on the differential design, bearing arrangement and factory setup measurements.
Do Not Order Based on R200 Identification Alone: Confirm Nissan part number 38165-10V01 and the required spacer length against the applicable Nissan factory parts catalogue and workshop procedure before purchasing.

What Does the Drive Pinion Bearing Spacer Do?
The differential drive pinion transfers rotational power from the driveshaft to the ring gear inside the differential housing.
The pinion shaft is supported by bearings that allow it to rotate smoothly while maintaining its required position relative to the ring gear.
The drive pinion bearing spacer forms part of the assembly between the relevant pinion bearing components, depending on the differential design.
Its dimensions are important to the relationship between the bearings and the required preload adjustment.
When the differential is assembled correctly, the bearing arrangement must provide the specified rotational resistance without excessive looseness or loading.
An incorrectly selected spacer can prevent the differential from achieving the required factory bearing setup.
46.80 mm Selective-Fit Spacer
Nissan part number 38165-10V01 is identified as a 46.80 mm spacer.
This dimension is the defining specification for the component offered in this listing.
Nissan uses different spacer specifications across its differential applications to accommodate the required assembly and adjustment arrangements.
Important: The 46.80 mm specification should not be treated as a universal R200 differential spacer length.
The correct spacer must be selected according to the differential's actual measurements and applicable factory service procedure.
Do not assume that the spacer originally installed in a differential remains the correct selection after changing bearings or other internal components.
Selective-Fit Spacer vs Collapsible Crush Sleeve
Differential pinion bearing assemblies may use selective-fit solid spacers, collapsible spacers or other adjustment components depending on their design.
A selective-fit spacer is selected according to the required dimensions and adjustment procedure.
A collapsible spacer, commonly called a crush sleeve, is designed to deform during the specified assembly process to establish the required bearing preload.
These components are not automatically interchangeable.
Important: Always identify the exact spacer arrangement used in your differential before ordering or installing replacement parts.
Why Correct Pinion Bearing Preload Matters
Pinion bearing preload is the controlled bearing loading established during differential assembly.
Correct preload helps the bearings operate as intended while maintaining the required pinion support.
Incorrect preload may result in:
- Excessive bearing heat
- Premature pinion bearing wear
- Rough or noisy differential operation
- Insufficient pinion shaft support
- Unwanted pinion movement
- Accelerated internal component wear
- Potential damage to the differential assembly
Important: The spacer alone does not establish the complete differential setup. Pinion bearing preload, pinion depth, backlash and ring and pinion contact pattern must be checked as required by the factory workshop procedure.
Ideal for Nissan R200 Differential Rebuilds
As Nissan Skyline and other Japanese performance vehicles age, professional differential rebuilds are increasingly common during restorations, repairs and driveline upgrades.
Precision internal components such as pinion bearing spacers are particularly important when replacing bearings or setting up the final drive assembly.
This genuine Nissan spacer is suitable for:
- Professional R200 differential rebuilding
- Pinion bearing replacement
- Factory final drive restoration
- Correcting an improperly assembled differential
- Replacing a damaged or incorrectly sized spacer
- Ring and pinion servicing
- Precision differential bearing setup
- Maintaining compatible original Nissan differential assemblies
Recommended Related Differential Components
When rebuilding a compatible Nissan R200 differential, inspect the condition and specification of all associated components.
Related items may include:
- Front drive pinion bearing
- Rear drive pinion bearing
- Differential carrier side bearings
- Drive pinion oil seal
- Pinion nut and retaining hardware
- Applicable bearing adjustment shims
- Collapsible spacer, where specified by the differential design
- Ring and pinion gear set
- Differential side oil seals
- Correct differential oil
Rebuild Tip: Record the original component arrangement and relevant measurements before disassembly. Follow the factory workshop procedure when selecting replacement spacers and establishing bearing preload.
Installation & Differential Setup Information
Drive pinion bearing spacer installation is a precision differential repair requiring specialist tools, accurate measurements and knowledge of final drive setup procedures.
The correct spacer specification must be determined before final assembly.
Depending on the differential design, installation may involve:
- Inspecting the pinion shaft and bearing mounting surfaces
- Installing the correct front and rear pinion bearings
- Selecting the required spacer specification
- Measuring pinion bearing rotational resistance
- Verifying the specified bearing preload
- Checking ring and pinion backlash
- Inspecting the ring and pinion contact pattern
- Completing final assembly using the specified hardware and procedures
Do Not Install Based on Spacer Length Alone: A 46.80 mm spacer is only correct where that specification has been established for the particular differential assembly.
Professional Installation Strongly Recommended: This component should be installed by a qualified differential specialist familiar with Nissan R200 final drive assemblies.
Incorrect spacer selection or installation may result in excessive bearing preload, insufficient bearing support, noise or premature differential failure.
