TTS M8 Performance Valve Springs

These Milwaukee-Eight Beehive shaped valve springs are made to withstand the High Performance needs of higher lift camshafts like the TTS 200 and TTS 250 cam profiles. Manufactured from quality chrome silicon based wire that is shaped, heat treated and shot-peened to the highest standards. The unique shaped of the wire allows us to provide a high quality high lift spring in a smaller package size to properly control valve motion, without the need of excessive pressure which robs performance and decreases durability.

Set of 8 valve springs.

2000311

All '17 - '22 Harley-Davidson Milwaukee-Eight Models

These springs are drop in replacements for the stock M8 heads with no modifications necessary.

When installed at stock spring height (1.535") they will handle .585" valve lift and when installed at 1.550" they will handle .600" Valve lift.
