Description

EC 26lb Valve Springs – Honda GX200 / Clone / Predator Engines


The EC 26lb Valve Springs are one of the most robust single-spring options available for modified Honda GX200, Clone, and Predator 212 engines. Designed to deliver reliable valve control at high RPM, these springs are ideal for builds turning up to 8500 RPM with less than 0.290” total lift.


These high-performance springs are a popular upgrade for racers seeking increased RPM range and improved valve stability, especially when using stock-size valves, automotive-style split keepers, and lightweight valvetrain components.


Key Features:

  • Engineered for race-prepped small block engines
  • Handles up to 26 lbs of seat pressure at .825” installed height
  • Compatible with camshafts up to ~0.275” lift (net valve lift < 0.300")
  • Excellent for stock valves (24mm–27mm) and stock rockers
  • Ideal spring for Banzai 265, Reaper, Mod 2, CL1, and other mid-lift cams
  • Works in most cylinder heads with minimal modification


Valve Spring Specifications:

  • Uninstalled Height: 1.05"
  • Installed Height Options:
    • 0.850” – Seat Pressure: 22 lbs – Max Lift: 0.375”
    • 0.825” – Seat Pressure: 26 lbs – Max Lift: 0.325”
  • Open Pressure (@ .475 lift): 68 lbs
  • Coil Bind Height: 0.435”
  • Outside Diameter: 0.829”
  • Inside Diameter: 0.635”
  • Wire Diameter: 0.095”

Note: Always verify installed height, retainer fitment, and clearance in your cylinder head before use. Larger springs may require spring pocket machining in certain heads.


Fitment Compatibility:

Fits most 5mm and 5.5mm stem valve applications in:

  • Honda GX160 / GX200
  • Clone 196cc Engines
  • Predator 212 Hemi & Non-Hemi
  • Predator 224
  • Tillotson 196R / 212R / 225RS / 236 / 268
  • Ducar 196 / 212 / 224
  • Wildcat 223 / 240

Need billet retainers? We offer aluminum retainers for both 5mm and 5.5mm valve stems.


Important Tech Note:

RPM capability depends on valvetrain weight, rocker arm material, and camshaft profile. While stock rockers and valves allow higher RPM, heavier components (e.g., billet steel rockers or larger valves) may cause earlier valve float, even within the same spring rating.


If you’re using a high-ratio rocker arm or aggressive cam, always calculate your net lift:

Net Lift = (Cam Lift × Rocker Ratio) - Valve Lash

Exceeding recommended net lift or RPM range without sufficient spring pressure can result in valve float or engine damage.

FAQ

Q1: What camshaft lift is compatible with these springs?

A: These springs are designed for camshafts with up to 0.275” cam lift and less than 0.300” total valve lift. Always measure net lift based on your rocker ratio and lash.


Q2: Can I use these springs with stock rockers and valves?

A: Yes! These are ideal for stock-size valves (24mm–27mm) and stock stamped rockers. Lighter valvetrain components reduce the chance of valve float at higher RPMs.


Q3: Will these fit a Predator 212 Hemi?

A: Yes, but you must verify your valve stem diameter (5mm or 5.5mm), retainer compatibility, and spring pocket clearance. Some Hemi heads may require machining.


Q4: What is the installed height and seat pressure?

  • At 0.850” installed height: 22 lbs seat pressure
  • At 0.825” installed height: 26 lbs seat pressure
    Make sure to verify your actual install height using a spring height gauge for best performance.


Q5: Can I use these with billet or Champion rockers?

A: You can, but be aware: heavier rockers and larger valves increase valvetrain weight, which may reduce the RPM limit before valve float occurs. A stiffer spring or dual-spring setup may be required in some cases.


Q6: Do you offer matching retainers?

A: Yes. EC offers billet aluminum retainers for both 5mm and 5.5mm valve stems to ensure proper spring seating and performance.
