Most decidedly NOT one of those flimsy plastic snap-together kits that falls apart if you so much as look cross-eyed at it. This Steel Works 4 x 4 Truck Construction Set is made of real steel secured with sturdy nuts and bolts that'll stand up to your young off-roader's adventures. It's a learning experience, too, since it gives builders a hands-on education in installing a working steering mechanism and articulating front wheels. The kit comes with everything you need, including more than 350 pieces plus detailed instructions and all the tools you'll need to put your new 4 x 4 on the trail.
