The EC 1.5 Ratio Roller Rockers fit the Briggs & Stratton Vanguard Briggs Model 30, Model 35, and Model 38 Vanguard V-Twin and Model 40, Model 44 and Model 49 Intek V-Twin Engines. 

These Rockers will also fit the Model 58 and 61 Big Block Vanguards.

1500 EC 1.5 Ratio Roller Rockers for both the Briggs 16-23hp Vanguard engines. These Roller Rockers are made from billet aluminum and have a 60rc hard roller tip. The 1.5 ratio adds 1.5 x cam lift for your total valve lift. The added lift and lightweight stabilization give huge performance gains and added reliability to your valve train. Please set your lash at 0.005" Check out our Technical Page for more diagrams and info.

1. Rocker arms may hit the top of the valve cover. You will need to fabricate a valve cover spacer for proper fitment.

2. The valve cover studs we supply are a little long on the hex side for people that use valve cover spacers. If you don't use a valve cover spacer, you may need to cut the stud length on the valve hex side to fit.

3. You must use a high-grade oil-soluble assembly lube when installing the rocker's arms. We recommend the Maxima Racing Oil Assembly Lube. 

Pour oil over the rocker's arms heavily to ensure your valve train is lubricated before starting your engine. 

4. Installation Check List

  • Valve Spring Install Height
  • Valve Spring Coil Bind at Max Lift
  • Retainer to Valve Guide Clearance
  • Piston-to-Valve-Clearance
  • Degree Camshaft
  • Measure and Set Rocker Arm Geometry
  • Measure and Cut Push Rod Length after Rocker Geometry is set.

Rocker Arms are not bolt-on installation and require expert engine-building tools and techniques. DO NOT ASSUME COMPONENTS WILL CLEAR. This is the number one reason for engine and rocker arm failure. There is no warranty on these rockers' arms, and they cannot be returned after installation.
