2004.5-2005 6.6L LLY GM Duramax
Differential Covers | Transmission Covers


Nothing finishes off the look for your Heavy Duty 6.6L GM Duramax like an aftermarket differential cover.  In addition to great looks, the large fins and increased fluid capacity of these covers helps keep your differentials cool even under the toughest conditions.  Couple this with a magnetic drain plug, dipstick, and an eyeglass to see the fluid, and you've got looks AND function!  And to keep your Allison transmission running as COOL as possible, don't forget to add an upgraded transmission pan to prevent coking the oil.

As always, if you have any questions about which cover or pan are right for you and your truck, do not hesitate to give us a call or send an e-mail to [email protected] and we would be happy to assist.
