The Fun Box Kits we build are the perfect centerpiece to your driveway park. This setup is made up of 2 of our larger banked Kicker Ramps (Big Momma!) that are 2’-8” wide. The center section is quick and easy to assemble and gives you 4’-0” of usable deck space. Add an 8” tall x 4’-0” Long Flat Bar to give yourself a complete tech set-up! When you need to store this tech masterpiece, you can easily disassemble it and stack it by removing only 8 screws!


As with all of our kits, the Fun Box Kits come standard with:

-          5/8” thick plywood templates

-          2 x 4 framing

-          3/8” thick plywood sub-sheeting

-          ¼” thick Finnish Birch top sheeting.

-          -12 ga. Galvanized thresholds

-          Exterior grade hardware

-          Complete and detailed assembly instructions


All plywood used in our ramp kits is exterior grade plywood and is all cut on a CNC router to ensure accuracy and an easy fit. Our 5/8” templates are available in ¾” thick exterior grade plywood as an upgrade.

If you want your ramp to last as long as possible, upgrade to ¼” thick Gatorskins Ramp Sheeting. This material is incredibly weather-resistant, available in several color choices, and is actually made for skateboarding!


There are no cutting corners here! We do it right, or we don’t do it at all!

    Back in the day, jump ramps taught me how to blast.

    At Ramparts we make 'em built to last and with twice the style.
