Radflo 2.0 Shock Bearing Spacers - 1/2" x 1.25" Stainless Steel (Pair)
KT-BR-53175
The Radflo 2.0 Shock Bearing Spacers – KT-BR-53175 are precision-machined stainless steel replacement spacers designed for compatible Radflo 2.0 off-road shocks and coilovers. Featuring a 1/2" mounting bolt bore and 1.25" overall mounting width, these spacers position the spherical bearing correctly within the shock mounting tabs while allowing smooth articulation throughout suspension travel. Manufactured from corrosion-resistant 303 stainless steel, they are built to withstand the dirt, water, vibration, and repeated suspension cycling common in demanding off-road environments.
Designed for shock maintenance, rebuilds, and replacement of worn mounting hardware, these Radflo bearing spacers help maintain proper shock alignment and secure mounting at the chassis or axle. The stainless steel construction provides durability and corrosion resistance for rock crawlers, trail buggies, prerunners, and custom suspension systems. Sold as a pair, each kit includes two matching spacers to service one spherical bearing mounting location.
Includes:
- (2) Radflo 2.0 Stainless Steel Bearing Spacers
Important: One pair services one spherical bearing mounting location. Spherical bearing, mounting bolt, and shock are sold separately.

- 303 stainless steel provides corrosion resistance in wet, muddy, and abrasive environments.
- Two spacers are required for one compatible spherical bearing mounting location.
- Verify spherical bearing dimensions before installation.
- Mounting hardware should clamp securely against the spacers without restricting spherical bearing articulation.
Fitment
Designed for compatible Radflo 2.0 off-road shocks and coilovers using a 1/2" mounting bolt and 1.25" mounting width. Fitment is determined by shock bearing and mounting dimensions rather than vehicle make or model.
Compatible Applications:
- Radflo 2.0 Off-Road Shocks
- Radflo 2.0 Coilover Shocks
- Compatible Upper and Lower Shock Eye Mounts
- Rock Crawlers and Rock Bouncers
- Trail Buggies and Custom Tube-Chassis Builds
- Prerunners and Off-Road Racing Suspensions
- Custom 4-Link and Long-Travel Suspension Systems Using Compatible Radflo Shocks
Fitment Notes:
- Requires a compatible Radflo 2.0 spherical bearing assembly.
- Designed for 1/2" diameter shock mounting bolts.
- Provides 1.25" overall mounting width when installed as a pair.
- Services one spherical bearing mounting location.
- Not intended for factory OE replacement shock applications.
- Other Radflo shock series may require different spacer dimensions.
- Verify bearing dimensions, mounting tab spacing, and bolt diameter before ordering.
- Inspect the spherical bearing and mounting hardware for wear during installation.
Builder Note: Correct bearing spacer dimensions are important for proper shock mounting. Spacers that are too narrow can allow unwanted movement, while incorrect spacer geometry can restrict bearing articulation or create interference during suspension travel. Always confirm mounting width and available articulation before final assembly.
FAQ
What do Radflo shock bearing spacers do?
Shock bearing spacers position the spherical bearing correctly within the shock mounting tabs and establish the required mounting width. They provide proper contact surfaces for the mounting hardware while allowing the spherical bearing to articulate as the suspension moves.
Will these spacers fit all Radflo shocks?
No. The KT-BR-53175 spacers are intended for compatible Radflo 2.0 shocks and coilovers using a 1/2" mounting bolt and 1.25" overall mounting width. Other Radflo shock sizes and bearing configurations may require different spacers.
What size are the Radflo KT-BR-53175 bearing spacers?
These spacers are designed for a 1/2" diameter mounting bolt and provide a 1.25" overall mounting width when installed as a pair in the compatible spherical bearing assembly.
Why are these bearing spacers made from 303 stainless steel?
303 stainless steel offers good corrosion resistance and machinability, making it suitable for precision shock mounting components exposed to mud, water, dirt, and changing weather conditions. Its corrosion resistance helps maintain clean mounting surfaces during off-road use.
How many spacers are included in one kit?
Each kit includes two matching stainless steel bearing spacers. This is enough to service one spherical bearing mounting location on a compatible Radflo shock.
Do I need one or two spacer kits per shock?
One kit services one bearing location. If your shock uses spherical bearings at both the upper and lower mounting eyes and both locations require replacement spacers, you will need two kits per shock.
Can these spacers be used on the upper and lower shock mounts?
Yes, provided both mounting locations use the same compatible bearing, 1/2" bolt diameter, and 1.25" mounting width. Always verify the dimensions at each mounting location before ordering.
When should shock bearing spacers be replaced?
Inspect bearing spacers during routine shock maintenance or whenever replacing spherical bearings. Replace spacers showing excessive wear, grooves, deformation, corrosion, or damage to the bearing contact surfaces. Worn spacers can contribute to unwanted movement, noise, and accelerated bearing wear.
Do these spacers include the spherical bearing or mounting bolt?
No. The KT-BR-53175 kit includes only two stainless steel bearing spacers. The spherical bearing, mounting bolt, and other shock hardware are sold separately.
Can incorrect bearing spacers damage a shock?
Yes. Incorrect mounting width, bolt diameter, or spacer geometry can cause improper clamping, restricted articulation, and unwanted loading on the spherical bearing. Verify the mounting dimensions and cycle the suspension to check for binding or interference before operating the vehicle.
