It is curious that the bolt will bend when the shock eye is lifted but doesn't bend when the shock eye presses down on the bolt.

I'm pretty sure there is a difference between lifting the weight of the rear and what the amount of pressure is applied to the bolt. ….. Mike

Aha, I see, this is only when you mechanically lift the bike and place three ramps. I thought there might be some obscure reason for reversing up the front ramps. Thanks for the clarification.

How can this possibly be the case, the mechanical advantage the rear wheel has over the shock is greater than the bike's rear weight, isn't it?

If the jack is on the shock " eye " … the BOLT that goes thru that " EYE " is also lifted …. and puts a lot of pressure ie. Force upon the two side brackets that contain the shock " eye " ….. you might be able to get the bolt to pass thru using B F H , but you won't ever get the bolt to pass back thru ….UNLESS you move the jack to some other location on the rear frame …. by using the method I described above in another post - you jack it up once and done …… but I do realize you have done the impossible ( the DESS module - removed with the Frunk still on ) …..

Seriously? Guys this is not rocket science about the bolt.
The rear shock installed has a spring on it. That spring supports the weight of the vehicles aft end and riders. Yes there might be a supplemental spring via the air bag.
In simple terms the spring supports the vehicle. Therefore the load into the bolt in a static non moving load is the least it can be with wheels on ground and vehicle weight on wheels.
Positioning a jack, under the shock eyelet and lifting the rear wheel, the load induced on the bolt is the droop weight of the rear suspension and tire / wheel / brakes. Regarding the bolt, that weight, including leverage, is far less than the weight of the Spyder with no air bag support.
The jack applies lifting force into the shock eyelet, this lifting force is applied into the spring. The spring transfer the force into the frame at the upper shock mount on the chassis.
You are far more likely to bend the bolt and the support tube by overloading the Spyder and bottoming out the suspension, or continuing to ride / bottom out from insufficient support from the air spring bladder.
To the original person posting, as you have read, many owners will use ramps in a safe manner to elevate the machine in the front to accomplish an oil change. Myself, on our Spyder, ramps are not viable since the trailer hitch mudflap would scrape badly. My method for oil change is either use the low height drain pan and not jack at all, or I raise the Spyder by jacking all wheels at once, then place ramps under the front tires, and use a concrete block and cap block under the rear tire. I do set the brake to prevent movement once placed on the raised supports.

I use DIY wooden ramps. Four pieces of 6 X 1 (yes 1 not 2), staggered to obtain the ramp up effect, for a total of three inches high. I used leftover cedar planks. I use three such ramps, one for each wheel. Works for me.

Hmmm, this all has me confused as I try picture the front wheels on the car ramps. I can see where more weight is shifted to the rear of the machine so that the extended mud flap may drag, as on the 2020 RT, one day someone will do a U Tube and it all will become clear.

i bought some half height plastic ramps
they are perfect for oil change on the spyder as both drain plugs are to the rear
you can drive up the ramps as they are not too high,but dont work so well on smooth concrete,as they tend to slip...rough concrete is fine tho

theyre 160mm or a bit over 6 inches
i've driven manual and auto up them...because they are low,its not intimidating to drive up them....except for slipping on the smooth concrete
and great for oil changes

Not the most elegant solution, but ramps don't slide when they got a backing piece and rebar stuck in the floor behind them. When you pull the backing pieces out and throw them under the tool box, all that is left is a few 1/2 inch holes in the floor. Works for me, and it was free. All the pieces came from my scrap metal pile.

I do the same as Steve, even with ramps you would have to lay on the floor, so why dick around with ramps? Just curious.

What do you mean by 1/2 height? They look like regular everyday common ramp height to me.

Yes, I'm curious as well.

Without measuring, they look to be about 4" shorter than my steel ramps.

Easy as can be without raising F3 at all. You just need to use a shallow pan to drain oil into.
