Kartboy Rear Diff Bushings Soft

That's because the rear differential is moving around on squishy bushings. Stop the movement madness with our harder bushings. These sandwich the rear sub-frame outriggers, and eliminate some of the squishiness. These aren't the super-hard race version, but they're definitely stiffer than stock. They're still comfortable for every day, but you may experience a slight increase in NVH. You have been forewarned.
