COMP Cams Short Travel XD Hydraulic Roller Lifters
COMP Cams short travel XD hydraulic roller lifters offer the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. The XD versions feature heavy-duty tool steel pushrod seats. This adds strength and durability in extreme-duty applications, such as turbo drag cars and offshore powerboats. Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valvetrain. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. Now you have the best of both—with COMP Cams short travel XD hydraulic roller lifters. Order the model designed for your vehicle and engine application.

March Performance Small Block Chevy Ultra Serpentine Conversion Kits
March Performance small block Chevy Ultra serpentine conversion kits will make it easy to convert your old V-belt pulleys. They bolt to the front of any 1969 or later small block Chevy heads and are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. The included bracket kits come complete with stainless steel tensioning rods and chromoly rod ends for high performance operation. Required mounting hardware is included and is powdercoated to eliminate polishing in those hard-to-reach places. Matching serpentine pulleys are precision CNC-machined from 6061 T-6 aluminum. These pulleys will not fracture like common cast pulleys because they are hard coated in the high-wear areas on their high water flow ratio pulleys. The street rod ratio increases water flow and fan speed. This helps at critical low-speed driving.

They're available in both tall and short heights, with either a chrome or black crinkle finish.
