Smoker Quarter Midget Idler Hub

Engineered for precision and performance, the Smoker Quarter Midget Idler Hub is designed to give your car smoother rotation and less rolling resistance — where it matters most. Built with a wide, high-quality bearing, this lightweight hub delivers excellent durability and consistency lap after lap.

Why Use a Free Hub on the Left Rear?

In oval racing, traction and rotation balance are everything. Running a free (idler) hub on the left rear allows the inside rear wheel to spin freely through corners, rather than being locked to the drive axle. This setup helps the car rotate more efficiently, reduces rear-end bind, and keeps the car from pushing or scrubbing speed mid-turn. The result is:

• Faster corner entry and exit speeds

• Improved handling through tight turns

• Less tire wear on the left rear

• Reduced drag on straightaways 

By freeing up the inside rear, you allow the right rear tire — your primary drive tire on an oval — to do its job more effectively, translating to quicker laps and more consistent performance.
