After running the truck with its stock wheels and tires on nearly every
surface imaginable, I wanted to drive it on some textured concrete at a
park near my house that is notorious for chewing through off-road tires
but I didn’t want to ruin the DBoots that came with the truck as they
had proven to work so well on so many different types of terrain. I have
a set of Pro-line Road Rage tires for a 1/8 buggy and also a set of
slicks from Ofna, either of which would work on the concrete. What I
didn’t have was an aftermarket way of mounting 17mm hexes to the Senton.
There are few option parts offered for the truck so far as it is so new
and I didn’t see an immediate answer to making the wheels fit.
After digging through my collection of 17mm adapters for other SC trucks
and realizing that none of them would work with the M6 axles, I had a
“eureka” moment: my E-Maxx uses a large roll pin and M6 axles and I have
a set of adapters for it that would work, if I could find them. I dug
through every box in my shop and finally found them and they were a
perfect fit. The adapter is held to the axle by inserting the roll pin
through the adapter, then the axle and capturing it with a set screw.
This eliminates the need to use a nut to secure the adapter to the end
of the axle. The offset of the adapters keeps the wheels inside the
fenders and the tires don’t rub the fenders even during full compression
of the suspension. Ignore the mini-pin tires that I had on the truck
during mock up, they were the closest set that I had to test as I was
cleaning the street tires in a bath of Simple Green at the time and
didn’t want to wait until they were done to test the setup.
These particular adapters were made by Ofna in the eary 2000’s (I think I
got mine in 2002) but I am fairly certain that any 17mm hex conversion
for a 2.5 T-Maxx or E-Maxx (any Maxx model that doesn’t use the new
style 3.3 axles) will work if they mount in a similar way. I have not
tried a set of adapters for a 3.3 yet so I can’t say whether or not they
would work, but the 2.5 style fits great.
The OFNA adapters had a part number of OFN81175 but are no longer available.
