You're looking at the Build a Pump kit for 1:10 scale lowriders. These model pumps fully come apart for painting or plating of each individual part of the pump. They are held together with real metal hardware for an authentic look. These pumps measure 1.83in by .84in on my digital caliper, please see pics for measurements. Parts are 3D printed with the toughest of resins for durability. Pump tanks have a small circular groove on the underside for adding magnets or velcro for mounting. The pump head features a snap lock system for easy assembly and disassembly. Holes were added to the battery terminals to easily add wiring for an even more authentic look. Battery racks, bars and metal hardware included as well. This kit will include 2 Build a Pumps in raw print material, as well as 2 battery racks with hardware and 6x batteries. Kit may require a battery relocation or removal to fit as shown. Kit is shown in the trunk of a Redcat Sixty Four Impala Lowrider for size and scaling purposes only and is not included with pumps. Check out my other auctions for 4 Pump kits and individual parts. Shipping only to the lower 48 states at the time. Thanks and have a great day!
