RFY Shock Rebuild Overview
- Replace unknown factory shock fluid with Maxima fluid providing known damping properties
- Purge air from damper system providing consistent performance throughout suspension travel
- Proper bladder pressurization with purpose built tool means precise control of damping characteristics (standard tire gauges do not work for setting this pressure as the bladder volume is too small!)
- Proper pressurization reduces oil cavitation and keeps the damper working consistently no matter how long or far you ride
- The use of pure nitrogen eliminates moisture in the system while providing greater temperature stabilization compared to air
- Apply friction reducing seal grease ensures smooth damper operation and longer seal life
- Additionally, top out spring replacement is available, see below for details
The RFY shock rebuild includes: Maxima shock oil (3, 7, or 10 weight), complete inspection, charging with nitrogen, optimization of shock dimensions, complete reassembly, and high quality valve stem caps. Additionally, once the shocks have had their initial service, the cost is reduced to only $65 for each reoccurring service.
Top Out Spring Replacement and Preload Correction
Top out spring replacement removes the overly stiff and excessively tall factory spring. This accommodates greater travel in the sag component of your suspension travel. The replacement spring decreases the droop limit, meaning the shock has a longer travel than stock. Ultimately, this allows the setup of the shock to be maximized in both the compression and sag characteristics. Preload correction is applied in conjunction with the top out spring replacement and serves to reduce factory set preload as much as possible. This is ideal for lighter bikes and riders who may struggle to achieve popper sag. Note: this service may add up to 10mm to the total length of the shock.
If you are uncertain on oil weight, generally speaking 7w is the best choice.
Spherical Bearing Modification
The spherical bearing modification adds spherical bearings to the eyelets of RFY and CL MotoTech shocks. This is a premium upgrade for the performance oriented individual. The benefits of spherical bearings are many:
- Reduces misalignment forces on the shock piston and shock rod linear bearing
- Increases shock sensitivity
- Lessens fiction and wear on shock components
- Less rotational friction that results in smoother action of the suspension
- Removes free play or slop common with rubber lined mounts
- Easily changed when worn
- A more professional and clean aesthetic
- Extremely long life with proper maintenance
The downsides of this modification:
- Greater maintenance requirements, cleaning, lubrication, etc.
- More expensive replacement
All spherical bearings have a 15mm inner diameter, though bushings will be supplied to adapt that to 8mm, 10mm, 12mm, and 14mm mounts.
To adapt your RFY shocks for spherical bearings the shocks must be partially disassembled. Once this happens the shock cap is then milled via a vertical milling machine to fit the spherical bearing. The bearing is retained with an internal circlip. A similar process is performed for bottom eyelets. All of these processes are inclusive in the purchase of this item.
This process is always performed to the top eyelet, the one that is an integral part of the shock. For those with clevis mounts, you only need the Dual Conversion. For those who have eyelet lower mounts, you can choose to have the Quad Conversion. The Quad Conversion converts the upper eyelets and the lower eyelets to spherical bearings.
Note: This process is not reversible, once your shocks have been modified to accept the spherical bearing they are like this permanently.
Once I have received your shocks they will be serviced and return mailed within 7 days and usually quicker. However, added features such as the spherical bearing modification will extend this time.
