Jimmy's 4X4 sells a variety of off-road buggy parts. The store also provides building advice for off-road or track races that take place in the United States.
As a two-seat motor vehicle with an open top, a buggy shares many things in common with a go-kart, but a buggy is larger and much more powerful. A dune buggy features very large wheels like those seen on tractors.
Jimmy's 4X4 specializes in creating turnkey builds. Turnkey build buggies are created with coverings of regular car models, such as a Jeep Wrangler body cover.
The store offers a variety of off-the-shelf parts from brands that include QA1, Maxxis, American Racing, Turn Key, Walker Evans Racing, ATL Fuel Cells, Stak 4X4 and PCS, as of June 2015. If off-the-shelf parts do not satisfy a driver's needs, the store can make custom fabrications for an array of part categories. It manufactures its custom buggy parts to be more effective for off-road racing than common off-the-shelf alternatives. Custom parts offered by Jimmy's 4X4 include links, link mounts and tabs, steering arms, body hoods, axles, chassis and custom interiors. Jimmy's 4X4 cites a number of buggies that use their custom parts and frequently place high in off-road races.
