Limiter bushings for MSD Pro Billet mechanical advance. Bushings are CNC machined and fill the gap that MSD failed to recognize and supply. MSD bushings allow down to 18* advance. For some engines with larger camshafts, that doesn't allow for enough initial timing. Lack of initial timing results in poor starting, rich idle set up, poor low end performance and too much drop when placed in gear.
The bushings help solve the above issues.
Bushings are $10 each plus shipping from Indio, CA
