Product Description
DMS 10" 10 Rib Lower Pulley for LSA/LT4 With ATI Balancer
The DMS 10" 10 rib balancer pulleys are a great way to increase supercharger RPM resulting in higher airflow and boost levels. These pulleys are CNC machined from 6061 aluminum and anodized for longevity. Designed to fit ATI balancer part numbers 918856 or 918854. The 10.00 can go from mediocre boost up to max effort boost depending on the upper pulley choice. Idler relocation bracket is required.
Increase:
LSA = 28% Overdrive
LT4 = 25% Overdrive
Important Notes:
- LSA setups using 9.20" and larger pulleys require a DMS Idler Relocation Bracket.
- 6th Gen ZL1 and 3rd Gen CTS-V vehicles using 10.0" pulleys may require sway bar spacers.
