Description
Achieve superior valve actuation and maximize engine output with the MAX LIFT BSR Shaft Rocker Kit from Comp Cams, designed specifically for AFR and RHS LS3 heads. This kit addresses the need for precise rocker ratio control, offering a 1.70:1 ratio that increases valve lift, directly enhancing airflow and combustion efficiency.
By increasing the valve lift ratio to 1.70:1, this rocker kit allows for greater valve opening without compromising timing, resulting in improved engine breathing and power delivery. The shaft-mounted design provides enhanced stability and reduces deflection compared to stud-mounted rockers, ensuring consistent valve operation under high RPM conditions.
- Compatibility: Engineered exclusively for AFR and RHS LS3 cylinder heads, guaranteeing a precise fit that maintains factory geometry and simplifies installation.
- Durability: Constructed from high-strength materials to withstand the rigors of high-performance environments, the kit supports sustained operation without degradation.
- Dimensions: With a compact profile—66.00 cm length, 7.60 cm width, and 12.70 cm height—this rocker kit fits seamlessly within engine compartments designed for LS3 architecture.
- Weight Efficiency: At 5 kg, the assembly balances strength with lightweight construction, reducing inertia on the valvetrain for quicker response.
This rocker kit transforms the valvetrain’s mechanical advantage, offering measurable gains in horsepower and torque by optimizing valve lift and timing precision. Its shaft-mounted design minimizes deflection and wear, extending component life and maintaining consistent performance during aggressive driving or racing conditions.
Installation is straightforward on compatible AFR and RHS LS3 heads, minimizing downtime and ensuring reliable operation. The kit’s engineering focuses on maintaining OEM geometry, which preserves engine reliability while unlocking additional performance potential.
Comp Cams’ MAX LIFT BSR Shaft Rocker Kit is a strategic upgrade for serious LS3 engine builders seeking precise valve control, enhanced durability, and measurable performance improvements. Integrate this component to elevate your engine’s efficiency and power with confidence and engineered precision.
