Four fully assembled wheel sets as used in out Pullman PS-1 boxcar instructions. Enough to outfit one car. Want to build additional cars? These wheel sets will get you up and running right away.
These wheel sets come fully assembled, with ball bearings preinstalled in new LEGO® Technic bricks, custom sized axles to fit the bearings, washers to prevent wheels from rubbing the bricks and causing excess friction, and new LEGO train wheels.
Why use bearings? Because ball bearings provide excellent free rolling operation. Better than stock LEGO wheel sets. Less resistance means the rail car is easier to pull. And the easier a car is to pull the less strain on locomotives, and the more cars you can pull.
Includes: 8 wheels, 8 bearings, 8 technic bricks, 8 washers, and 4 axles. Comes fully assembled.
