This JAZRIDER metal shielded ball bearing set is intended as a direct upgrade for the Tamiya 56371 1/14 Scania 770 S 8x4/4 Truck. The complete 38 piece pack replaces common bushing points to lower friction and improve overall drivetrain consistency.
The kit provides 4 x 6 x 12 x 4mm, 32 x 5 x 11 x 4mm, and 2 x 5 x 8 x 2.5mm bearings. These items cover the standard bearing locations for a full conversion on the Scania model.
Metal shields protect rolling elements while keeping contact surfaces tight, offering a balance between protection and low rolling resistance. They are a sensible upgrade for regular running and reduce routine maintenance demands.
