Expect robust acceleration in the upper RPM band and reliable shift behavior with compatible gear setups.
- Dyno-verified gains: about +93 HP with proper CK/MK pairing
- High RPM acceleration: strong performance in the 6,700–7,300 RPM range
- Shift recovery: maintains power during manual shifts
COMP Cams 54-500-11 XFI 235/240 Solid Roller Cam
The XFI 235/240 cam is a strong upgrade option for GM LS GEN III/IV engines, offering a broad operating window suited to both mid-range torque and peak power. It’s positioned as a practical step up from factory cams, delivering enhanced torque and mid-range power with a broad RPM range. The profile is designed to work well with standard valve springs when properly matched.
- Great factory cam upgrade
- Torque and mid-range power improvement
- Operating range: 1,000–5,500 RPM
KAISAL Sloppy Stage 2 Camshaft (.585/.585) for LS Gen III/IV
KAISAL’s Stage 2 camshaft is designed for LS engines in the 1997–2007 range, offering substantial lift (.585″/.585″) and a 112° lobe separation angle. This hydraulic roller option emphasizes reliability, direct replacement compatibility, and a robust RPM range around 2,200–5,400. It’s not recommended for AFM/DOD-equipped engines, and it pairs best with upgraded valve springs for maximum performance.
- Wide compatibility with 1997–2007 LS engines
- High lift (.585″ intake and exhaust)
- Recommended PAC1218 springs for best results
zayody Sloppy Stage 2 Camshaft (.585/.585) for LS LSx
The zayody Sloppy Stage 2 cam is positioned as a durable replacement option for GM Chevy 1997–2007 LS engines, with the same high-lift profile and 112° LSA. It emphasizes long-term reliability and stable performance under varied driving conditions. As with similar Stage 2 parts, use care with AFM/DOD configurations and ensure compatible valve springs for longevity and peak output.
- Notable stage-2 lift for LS engines
- Stable operation with proper springs and tuning
- Replacement part for E-1840-P lineage
Buying Guide: Key Considerations For Solid Roller LS Cams
- Engine hardware compatibility: Ensure the cam is compatible with your LS variant (LS1/LS2/LS3/LS6/LSX) and with your existing or planned head setup, cam gears, and lifter type. Solid rollers require precise matching with valve springs and retainers.
- RPM targets and power goals: Stage 2 cams generally target higher RPM bands and increased horsepower, especially when paired with CK/MK or other matched components. Define your primary use—street, drag, or street-legal race—to pick a cam with the right RPM window.
- Valve train durability: Solid rollers can demand higher spring rates and stiffer components. Check recommended spring packages and installation torque specs to prevent valve float and wear.
- Driveability vs. peak power: A more aggressive cam often reduces idle quality and street manners. Consider intake, exhaust, and tuner support to balance daily usability with power gains.
- Support and tuning: Ensure dyno support or professional tuning is available to properly calibrate idle, timing, and air-fuel ratios after installing a solid roller cam.
- AFM/DOD considerations: Some Stage 2 and sloppy stage cams are not compatible with active fuel management systems. Verify compatibility with your vehicle’s AFM/DOD configuration.
- Leverage and reliability: Look for dyno data and reliability notes from the manufacturer. Many solid rollers are dyno-developed with observed horsepower gains, but results vary by hardware pairing.
- Installation and warranty: Review installation guides and warranty terms. A cam swap is a prime time to inspect lifters, pushrods, and timing chains for longevity and performance.
Across these options, brands like Comp Cams and KAISAL provide tested profiles designed for LS builds. The right choice depends on your engine’s combo, supporting parts, and the RPM range you intend to exploit. With careful matching and proper setup, a solid roller LS cam can yield meaningful horsepower and improved throttle response for street and track use alike.
