Triumph TR2 TR3 TR3b & TR4 - Performance Roller Rocker Set

• Our Roller Rockers reduce friction and wear = increased horsepower.
• Less side-loading on the valve.
• Greater Valve Life.
• Slightly more aggressive that the stock ratio (1.5:1 vs. 1.45:1), but still very streetable.
• Reduces valve chatter.
• Ratios are more accurate from rocker to rocker (vs stock rocker arms), making the lift more even across all of the cylinders.
• Can be used on your stock shaft (inspect to make sure its in good condition).
• Reuse your stock adjusters.
• Valve clearance remains set to standard.
• FREE SHIPPING FOR ALL U.S. AND PUERTO RICO ORDERS !!

NOTE:  The original slanted valve cover that came on all cars from the factory can sometimes interfere with these rockers as these roller rockers are slightly taller. To compensate for this, we recommend using an after market valve cover, or doubling up on your valve cover gasket for clearance.
