The new thing in RC Monster trucks seems to be these new shocks from eBay (and other sources) so I decided to make some faux reservoirs to put on them to make them look more realistic... You'll need eight of them...
If you want these in a larger size... Mod19Rc has something very similar

***NOTE: THE BOTTOM HOOP ON THE RESERVOIR IS PURPOSELY TIGHTER THAN THE TOP SO YOU CAN DREMEL/FILE IT A LITTLE FOR A SNUG FIT WITHOUT GLUEING***
