Once the sprocket alignment has been set, install the outer drive chain onto the two sprockets, lining up the timing marks.

Install all 3 pieces onto the engine at the same time, and install the appropriate bolts for each sprocket. Always use blue

Loctite on the threads, and torque the bolts in place. The special sprocket locking tool makes torqueing these bolts a cinch.


Release the outer Cam Chain Tensioner.


Install the outer Cam cover, following the factory torque spec and torque pattern.

ALL Gear Drive Cams


For any gear driven cam, read the instructions and warnings provided with the gear kit.


Install the inner gears onto the camshafts.


Install the bearings onto the new camshafts (’99-06 only). On an ’07-UP model, coat the outer bearing journals with

assembly lubricant. Install the assembly in the cam support plate.


Install the cam assemblies into the cam support plate. Double check the timing marks once installed, both on the outboard

side of the cams, and the gears themselves.


Coat the lobes and inner bearing journals with assembly lubricant.


Reinstall the cam support plate into the cam chest. Torque in place


The oil pump should be fastened to the cam support plate, and torqued in place.


Install the outer drive cam gears. Check the outer cam gear backlash, and follow the procedures in the gear drive kit.


Torque the cam gear retaining bolts in place, using Blue Loctite.


Install the outer Cam cover, following the factory torque spec and torque pattern.

All Models – Final Setup Tips:

1.) Anti-Rotation Pin –

Allowable Lifter Rotation – Now that the cam chest is

assembled, install the hydraulic lifters into the engine. Make certain that you

have the oil feed hole in the lifter facing outward. Using a set of feeler gauges,

measure the clearance between the center of the anti-rotation pin, and the

casting, when both lifters are positioned on the base circle of the cam. Do not

measure at each individual lifter.

Red Shift recommends between 0.002”to 0.004” of clearance. Oversized pins

are available in +0.002” and +0.006” sizes. Most will require the use of the

+0.002” pins for proper clearance. Both too much, and too little clearance will

result in operational issues. Not enough clearance can cause the lifters to

stick, and too much clearance will allow the lifter roller to turn and side load

under operation.

2.) Pushrod Adjustment Procedure -

Only for Adjustable pushrods

a. DRY - Starting with a dry lifter will allow full compression of the lifter, without risk of damaging the valve. Install

the pushrod, and fully extend it in place. Shorten the pushrod by 4 flats (2/3 of a turn), for proper lash. Make sure

to tighten the locknut to keep the pushrod at this length.

b. WET – If your lifters are primed or fully pumped up, you simply have to bleed the oil out of the lifter to find the

bottom. Install the pushrod and extend it fully to zero lash, with no pressure on the valve. Lower the adjuster 22

flats (3 -2/3 Full turns), and stop at this point to allow the lifter to bleed down. Once you can freely spin the

pushrod, adjust the pushrod down another 20 flats (3-1/3 turns). The hydraulics should be at the bottom, but give

it a few minutes to bleed down. If the pushrod turns, slowly lengthen the pushrod until the free movement is

contained. At this point, shorten the pushrod by 4 flats (2/3 of a turn), and tighten the lock nut.

3.) Fuel / Spark Tuning -

To optimize the output of your new Red Shift cam, both fuel and spark adjustments need to be

performed. The use of wide band oxygen sensors are highly recommended when tuning.
