The Factory Pro FP-B-CDB312 3mm Ceramic Differential Balls are supplied as a 12 count set for routine upgrades and rebuilds. Their ceramic construction delivers improved roundness and wear resistance compared to conventional steel parts, helping keep your differential running true.
Ceramic material reduces heat build-up and rolling resistance inside the diff, which translates into steadier behaviour during acceleration and cornering. That steadiness benefits drivers chasing consistent lap times.
These 3mm balls are suitable for a range of differential types where precision components matter. They are appropriate for both sealed and rebuildable diffs and support fine-tuning of traction and response.
