Why Is Ty Tessmann Running His Shocks Upside Down?

Why Is Ty Tessmann Running His Shocks Upside Down?

HB Racing’s Ty Tessmman had an impressive result with 2nd overall at the recent 2016 ROAR EP Off-Road Nationals in the 2WD class driving his HB Racing D216. Keen eyes noticed his use of inverted shocks. While this is unusual, it can help to lower the center-of-gravity when the conditions permit. Many armchair tuners have speculated that this may be isolated since the HB Racing D216 has higher than average towers and long shocks, but this still doesn’t overlook the possibility of others following suit. Interesting indeed. Wonder how many racers we will see experimenting with this newest tuning trend?

  1. I’ve been doing this for years. Especially in the rear. I learned it from Motocross in the eighties..

  2. not sure I would call it the “newest tuning trend” simply because many racers experimented with upside down shocks many decades ago:

    It would be nice to see a published tuning chart explaining under what conditions inverted shocks produce more good than harm. As seen in the pic I linked above, they only inverted the longer rear shocks and left the shorter front shocks alone.

  3. This is not new dirt oval racers have done this before to get as much weight down low and LTO chassis

  4. umm this is not a new trend people…. we were doing this back in the 80’s. the theory is that if you have air/ bubbles in your shocks they will rise, and the piston will go through these bubble quickly at the beginning of the stroke and get into the thick oil, vs the conventional way where the piston encounters this air bubble at the end of the stroke (ie: fully compressed)

  5. yes this is just plane old school tuning been doing this for decades . a lot of the newest compition kits now are not doing anything new as the old school tech is coming back .

  6. I started doing this with my RC10T version 1.0 in the early 90’s. It did make a difference even way back then.

  7. circle track both asphalt / dirt stock cars have been doing it sense the 60’s generally on rt, front and rears.

  8. Does this not add to the unsprung weight?

  9. Im doing this also with my scx10 for past few year..

  10. Not new. Did in the mid 80’s on RC-10’s. Was good on smooth tracks, but was too much sprung weight on the rougher tracks.

    1. Oops, unsprung weight. Retarded the travel speed of the arms at times.

  11. NEW TREND THAT ITS NEW NOW DURING THE RACES… NOT THAT HE IS INNOVATIVE IN THE IDEA, BUT ITS NEW THAT NOT MANY HAVE TRIED IT IN THE RC racing CIRCUIT.
