Optional Add-Ons

Four harmonic balancer bolts are also available as an option if needed. Please note these bolts are marked as "one time use only" and often round-out when being removed, so we strong recommend adding them to your order.

Injection pump sprocket bolts, are also an option in the kit. The factory bolts were green in color and one-time use.  The replacement bolts are gold in color and the gold colored bolts can be reused multiple times.

Coolant is available at a substantial discount when adding it as an option below.

Other Things To Consider

As the ALH engines increase in miles we have seen a few cases of camshaft sprockets that have developed fatigue cracks on the inside where it mates to the camshaft.  If the sprocket is fatigued it may not be able to hold the friction fit to the taper of the camshaft and may slip, causing valve-piston contact.  If you are at or above 300k miles we strongly recommend purchasing a new camshaft sprocket as well.
