Bolt-in. Higher valve lift and more duration means power from 2000–6000 RPM, stock or modified engines
Note: The compression release, compression release spring, compression release pivot pin, and the compression release pin set screw must be re-used from the old cams and installed in the Andrews camshafts which requires grinding the backside of the pin.

Andrews TS 550 Indian Chief cam

#572144

Stock:Yes

Requires high-lift valve springs. More lift and duration yields extra HP and torque in the 2200–6500 RPM range
Note: The compression release, compression release spring, compression release pivot pin, and the compression release pin set screw must be re-used from the old cams and installed in the Andrews camshafts which requires grinding the backside of the pin.

Andrews TS 570 Indian Chief cam

#572145

Stock:Yes

.640" valve lift. Without inner & outer gears. These are available from S&S as 503606. An S&S (503566) or Andrews (503660) camshaft installation kit provides all parts for installation as bearings, gasket etc.
Great cam for 95-107 inch engines with 10.2+ CR. Use high-lift springs. 2700-6500+ RPM.

Note: The inner drive gears are not installed on Andrews camshafts and must be ordered separately. Installation will require specialty tools.
Note: An outer drive gear set is also required for installing these cams and must be ordered separately.

Andrews, gear drive cam shaft set 59G/.640"

#503416

Stock:No

.450" valve lift. Street. This is the A cam with the longer exhaust duration of the Andrews B. Improved high end performance and reduced oil temperature in hot weather. Should install with no headwork (excl. 81-82).

Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.

Andrews, AB grind / .450" lift camshaft

#508695

Stock:Yes

.425" valve lift. Bolt-in. Hot street. Highest lift available without head work. Good mid and upper end power. Compression Ratio should be between 1:9 and 1:10 for best result. Can be used with stock springs.

Note: This 81-E84 cam set (generator models) does not have tachometer drive gears.

Andrews, Y / .425" Sportster cam set

#503605

Stock:Yes

.485" valve lift. Hot street. Much more midrange and top end power. Smooth idle. Good choice for modified motors and small strokers. Solid lifters recommended, spring spacing required.

Andrews, B2 grind / .485" lift camshaft

#503455

Stock:Yes

Available in chromoly steel and aluminum. Chromoly pushrods are thinner and have better flex resistancy than aluminum. Aluminum is lighter than chromoly and will reduce inertia mass. But for heavy duty service, like racing and/or high lift cams with high pressure springs it is still advised to run chromoly pushrods.

Note: See 503686 for chromoly pushrods.

Andrews, Twin Cam adj. aluminum pushrod set

#503687

Stock:Yes

Hot street/Drag. Modified 900/1000cc and strokers. Big boost in torque over stock cams. 2000-7500 RPM range. Can be used with stock springs. Stock spring OK but valve and piston clearance checks required.

Note: This L84-85 cam set (for alternator equipped models) does not have generator drive gears.

Andrews, R5 / .445" Sportster cam set

#503630

Stock:No

.490" valve lift. The low compression version of the Andrews B cam. High lift combined with short duration will improve performance on low compression engines (8:1 C.R. or less).

Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.

Andrews, 2 grind / .490" lift camshaft. (low CR)

#503520

Stock:Yes

Available in chromoly steel and aluminum. Chromoly pushrods are thinner and have better flex resistancy than aluminum. Aluminum is lighter than chromoly and will reduce inertia mass. But for heavy duty service, like racing and/or high lift cams with high pressure springs it is still advised to run chromoly pushrods.

Note: See 503687 for aluminum pushrods.

Andrews, Twin Cam adj. chromoly pushrod set

Stock:Yes

EZ-install pushrods can be installed without removing the rocker covers of fuel tanks, a big plus when switching to a bolt-in cam. Available in chromoly steel and aluminum. Chromoly pushrods are thinner and have better flex resistancy than aluminum. Aluminum is lighter than chromoly and will reduce inertia mass. But for heavy duty service, like racing and/or high lift cams with high pressure springs it is still advised to run chromoly pushrods.

Note: See 906696 for chromoly pushrods.

Andrews, Evo B.T. adj. EZ-install aluminum pushrod set

#503692

Stock:Yes

Yellow, oversize. Crimp-on installation on the camshaft. Used to correct backlash (free play) between the cam gear (on the cam) and the pinion gear (the smaller drive gear). Too much backlash will result in clicking, not enough backlash will result in a 'whining' sound. To correct backlash you can either use smaller or larger pinion gears or smaller or larger Andrews cam gears.

Note: See 503768 (.108") and 503769 (.105") cam gauge pins to measure cam gears and pinion gears.
Note: To determin if you need a 70-E77 or a L77-84 model Shovel cam gear? Measure the outer diameter of the cam gear on the camshaft that is to be replaced. The 70-E77 cam will measure approx. 70mm. The L77-84 cam will measure approx. 69mm.
