Radial Dynamics High performance hydraulic steering systems and engineering

After a couple weeks being backordered, our new batch of Pro Series TC pump castings have arrived and the guys are hard at work knocking out some of the finest TC pumps out there. Every pump is individually inspected for proper clearances, hand assembled, and dyno tested to make sure we deliver the exact performance our customers expect.

We recently had new castings custom designed with one minor change to the threaded inlet neck. The female port in the inlet neck used to be a non-standard ORB style port with 13/16-20 threads which meant that inlet fittings had to be custom machined. With the new casting design, which started with our previous batch a few months ago, the inlet now features a standard -10 ORB female port. While this does not affect most customers since we still include the appropriate male JIC adapter fitting, we have occasionally had customers that needed to swap elbows or different fittings for packaging purposes. Now they can do that using standard off the shelf hydraulic fittings.

Climb to the Clouds may be over but our fundraising efforts continue on. So far, sales from our "Climbing for a Cure" t-shirts plus independent donations have raised $4K for EB Research Partnership! We still have plenty of shirts left in stock as well, so we will be keeping these up on the website and will continue to donate 100% of proceeds until they sell out.

EB, short for Epidermolysis Bullosa, is a family of rare genetic skin diseases that affect one of my family members and every dollar raised directly funds research which has resulted in three FDA-approved treatments in just the last few years with goals of finding a cure by 2030.

Thank you to all who have supported this great cause!

Practice day 1 on the upper half of the mountain was smooth sailing, resulting in a best time of 3:12 which was good for 30th out of 84 entries and first in class by two seconds. It's going to be a fun matchup with our only Modified Electric class competitor, a road racing car which comes from the opposite end of the motorsport spectrum from Kermit. Today we run the lower half of the mountain which means more trees. Can't wait!
