M/R Racing Equipment Shock Dyno Service

 M/R Racing is proud to offer a Shock Dyno Service. We have recently purchased a Roehrig 2VS Shock Dyno in order to provide you with the latest in technology. The 2VS is equipped with the same ROEHRIG SHOCK™ Test Control and Damper Analysis software used by all NASCAR Nextel Cup teams and major shock manufacturers.

 We will dyno test most makes of shocks and provide you with a completed printed copy of your dyno sheet, this will be useful to you especially when making shock adjustments at the track. It definitely becomes easier to understand the changes you are making if you can see the changes in the damping force on a dyno graph in front of you. Whether you are racing on dirt or asphalt, this service will only improve your set-ups & handling. 

 You can drop off your shocks at the M/R Retail Store in Waldo or you can ship them to us for testing. We will try to have a 2-day turn around on all orders.

 Service Fee for Shock Dyno Service - $10.00/ea

(Note: $10 Fee for any excessively dirty shocks that we need to clean before we dyno)

 Please call  920-528-7090 or email mrracingtech@msn.com if you have any questions.

M/R Racing Equipment Spring Rate Service

As in the past, M/R Racing will continue to provide Spring Rate Service to all of our customers. There is no charge for this service, most springs are rated when you bring them in. If for some reason we do not have time at that moment, you can drop them off and we will have them ready for you the next day.  Stop guessing, now you can pinpoint spring rates to determine high accuracy splits and enhance chassis tuning.

Note: We have over 1000 used springs for sale, we sell used springs for $20/ea and will take most of your springs on trade at $10 a spring. This is a great way for you to change/test new set-ups without spending a fortune on new springs. Click here for a complete list of our used springs for sale. All used springs are rated before putting on our shelf for sale.
