Both styles weigh nearly the same. The Theeves truck we have stocked is a larger size so the weight will also be a little more than the smaller sized Thunder truck. Here are the weights: Thunder Thunder Lights Trucks__sz 7.65 = 11.24oz each Theeve Pro TiAx Mid Trucks__sz 7.75 = 11.96oz each
Yes, the Thunder Thunder Lights Trucks in the 7.65 size would be a good choice to put on an 8" deck. It is best not to have the trucks extend past the board.
I've made the buyer aware of the Thunder Thunder Lights Trucks not showing up in the customized section on the website. I imagine some things will be tweaked in the system and the trucks should show up in the custom complete section in a day or so. Please contact our Customer Service Team if you continue having difficulties building a complete with these trucks.
There are no orders in the system to replenish either style showing on the website for the Thunder Thunder Lights Trucks. If looking for different sizing, it appears there will be no other choices for this truck. Nor are there any other colorways created in the system under this model.
