In the beginning
there was the Traxxas stock shock, then came the Associated T-Maxx shock set.
From there we went to RPM dual stage pistons, Progressive piggybacks and

Threaded body SuperShock. I convinced them to import a few for me to test after
seeing them at the Chicago Hobby show in '01. I received them and had
to make some special standoffs since the upper mount is Ø6mm instead of the Traxxas standard of Ø5mm.
impressive to say the least. It's now a year and a half later and they have
proven themselves to be the best shock for this application.
shock per corner. My Racetruck weighs in just over 10lbs RTR.
I personally pounded the tar out of these (see those flipping
vids) and they
took it. Watching the vid I think I'll need to increase the oil weight just a
tad for the big jumps (you can see the rear bounce a bit), but you can see the
truck landing w/ no rebound from the medium ones. I'm running 50wt in the front
and 45 in the rear with Trinity Black springs, ~1/4" of preload in he front
and 3/8" in the back.
Rubber booties keep the dirt off your shafts and away from the seals, also
making clean-up a lot easier.
These shocks are quite a bit longer than the std Maxx shock. When using a SM
suspension, even at the extremes of mounting holes (Tower #5, Arm #4) you'll be
using every bit of travel it's capable of. The SuperMaxx KnuckleHead towers have
an additional row of mounting holes above the original EXT & WideTrac towers
providing more room for adjustment.
Limit straps are also in the works - these will
prevent over-extension the suspension in a tumbling type crash (end over end.)
Earlier SM EXT Suspensions may need a little dremeling in the lower arm to clear the
oversize rod end on the shock.
Made to work with SuperMaxx Suspensions. May work with others, though they may
be too long. Most users find that when by using the SuperMaxx KnuckleHead Shock
Towers there is enough adjustability to make this work in most applications.
6-20-03 New Shock Kit: The RacerX SuperShock Kit. Included in the kit is
4 shocks and a full set of the new dual rate springs. We've also padded the
quantities so not only are you guaranteed to have enough parts to complete the
kit but several extra items as well. Perfect for those of you who run 4 shock
trucks, 8 shock trucks as well (use 2x kits.) We've discontinued the SHK-4a &
SHK-8a kits in favor of this new kit. Parts are in stock, I'll have the
instructions re-worked and the kits packaged sometime next week (end of June
6-12-03 NEW Dual Rate springs: We've made four new dual rate springs for the
SuperShocks. Dual rate springs are soft for their initial half the travel then
stiffen up for the second half providing the best of both worlds. These are
available in 4 different spring rates. We've powder coated them in 4 different
colors for easy identification.
From what we've seen so far running them on our racetrucks the blue one works
best in the rear and the red in the front. On our 8 shock heavyweight Brushless
E-Maxx we use 4 white in the front and 4 reds in the rear. Heavier (than our
racetrucks) 4 shock trucks will find that the blacks in the rear and blues up
front will work well. Your use may vary, though these 4 different spring rates
should cover all your needs.
We've made this kit to include 8 springs: 2 whites, 2 reds, 2 blues, and 2
blacks. In stock and available now.
