MRR Adjustable Remote
Reservoir Shock Absorbers
Please leave this manual with the customer
Thankyou for purchasing Dobinsons MRR 3-Way A justable Remote Reservoir Shock Absorbers.
Your shock absorbers are equippe with 3 a justable ials to a just the amount of low spee
compression amping (small ial on the reservoir en ), high spee compression amping (large
ial on the reservoir en ) an reboun amping (small grub screw/ ial on the ro en ).

Important: When a justing the ials o not over toque the ials. Each ial shoul
be able to be move by han or with the small a justment tool provi e . Do not
over-torque the ials at the en of the ial travel as this may cause permanent
amage to the components.
Compression
Compression Compression
Compression
The compression a justers operate by allowing a low spee blee path combine with a high
spee igressive shim stack to allow a justments in both the low spee shaft movements an
high spee shaft movements (note - this is not vehicle spee ). It is important to note that ue to
the nature of the low spee blee path bypassing the high spee compression stack that each
a juster oes have a small effect on the other i.e. the low spee will have a small effect on the
high spee an vice versa. Also, the higher the a juster is set to, the more affect the opposing
a juster will have with each click.

The low spee a justment is increase by turning the smaller a justment ial on the reservoir
clockwise an is ecrease by turning it anti-clockwise an has approximately 20 clicks. Low
spee compression primarily affects the compression amping uring low spee shaft
movements such as vehicle pitch, ive an roll, wheel traction an vehicle ri e (harshness an
plushness). Lower settings will provi e a smoother more compliant ri e but will sacrifice
stability whilst higher settings will result in a firmer less compliant ri e but provi e better bo y
control & stability. If unsure, choose a setting that you feel provi es goo vehicle bo y control
an stability without excessiveness harshness. If you are unable to achieve a firm enough
setting you can increase the high spee a justment to suit an if you are unable to achieve a
soft enough setting then you may re uce the high spee a justment. See the graphs below for a
sweep of the low spee compression a justments – NOTE: Every 2n click has been omitte for
clarity. High spee compression set at mi point.

The high spee a justment is increase by turning the larger a justment ial on the reservoir
clockwise an is ecrease by turning it anti-clockwise an has approximately 10 clicks. NOTE:
Turning the ial clockwise will screw the a justment assembly outwar as it is a left-han
threa , this is normal. You can use the tool provi e but o NOT apply a lot of pressure towar s
the en of the a justment range as it may result in component amage. High spee primarily
affects the compression amping uring high spee shaft movements such as harsh or square
e ge bumps an harsh vehicle lan ings. Lower settings will provi e a slightly smoother ri e but
will be more prone to bottoming out, whilst higher settings will result in a firmer less compliant
ri e but re uce bottoming. It is recommen e to choose a setting that is as low as possible
whilst minimizing bottoming. If you are unable to achieve a firm enough setting you can
increase the low spee a justment to suit an if you are unable to achieve a soft enough setting
then you may re uce the low spee a justment. See the graphs below for a sweep of the low
spee compression a justments. Low spee compression set at mi point.

Reboun
RebounReboun
Reboun
The reboun a justment is increase by turning the small grub screw/ ial a juster on the ro
en clockwise an is ecrease by turning it anti-clockwise. Struts have aroun 25 clicks an
shocks aroun 12. You can use the tool provi e to make a justments on shocks (there is also a
hexagonal hole cut out – this is use on some pin type shocks to rotate the shock ro clockwise
only to allow access to the reboun a justment screw). Reboun amping a justment affects
both high an low spee reboun valving. To little reboun amping can cause the vehicle to
wallow, can cause the vehicle to kick up harshly after large bumps, ips or washouts an can
cause frequent topping out. Too much reboun can cause a harsh ri e an when riving over
continue corrugations, bumps or whoops it can cause loss of traction, cause the vehicle to skip
an steer erratically an can cause the suspension to pack own towar s the bump stops.

If you are spen ing exten e perio s of time on ifferent terrains then you may wish to alter
your amper settings to suit the particular terrain, they can be recor e on page 6. Some tips
are below
-Roa an highway settings can be set to you esire ri e quality an vehicle stability
compromise
-Har pack corrugate irt roa s / Rough rocky terrains generally will require the
vehicle to be more compliant an therefore both LSC an reboun may be on the
lower si e
-San y con itions will generally require firmer settings to prevent bottom an with the
tyre pressures typically re uce , comfort will be less of an issue.
-For high spee repetitive corrugations/whoops/large bumps generally the reboun
will nee to be own quite low to maintain chassis stability an to prevent packing
an the LSC on the lower si e to allow suspension compliance
-If you are towing or have heavy loa s in the rear than the rear compression an
reboun valving can be increase .

Turn the a justers to the softest position – completely out in the anti-clockwise irection an
count the clicks in an recor your setting below. These shock absorbers are a high-
performance shock absorber esigne an engineere to run warm an therefore you may
experience a slightly firmer ri e when col . Gas pressures can be a juste also if require –
Minimum gas pressure for 18mm shaft – 140psi an for 22mm shaft – 120psi (Checke at full

The shock absorbers are esigne as an OEM replacement shock absorber an o not require
any specific maintenance however the shock absorbers shoul be kept clean, especially aroun
the shaft seal an perio ically inspecte for any signs of issues inclu ing: Visible oil leaks,
amage to the shock ro , hose amage or wear an any other obvious amage.
For race vehicles the nitrogen gas pressure shoul be checke before all races an the shock
absorber rebuilt with new seals, shaft gui es, wear ban s, oil an a complete clean every
2000klms.
These shock absorbers are 100% rebuil able an shoul only be rebuilt by a qualifie suspension
technician. NEVER open the shock absorbers without releasing the gas pressure. as they are
un er high pressure.
