Don't let pump-rub issues take down your 2001-2007 GM 6.6L Duramax LB7/LLY/LBZ, upgrade to a Merchant Automotive 10603 261XHD Transfer Case. Merchant Automotive addresses the common issues in the factory floor-shift transfer case, making their 261XHD a more durable and reliable choice when looking to upgrade or replace your already damaged unit.
Merchant Transfer Case Pump Upgrade
The GM transfer case use a gear pump inside the case that is driven off the mainshaft. This pump forces oil to the planetary as well as the drive sprocket sleeve. The 5 tabs around the housing fit into the spots in the rear housing are what positions the pump. Over time, the pump can start to wear on the rear housing. This is commonly referred to as pump rub. Each transfer case includes the Merchant Automotive Pump Upgrade to alleviate these "Pump Rub" issues.

Help extend fluid life, and the life of your transfer case with the Merchant Automotive magnetic drain plug. The drain plug catches debris instead of circulating it through the case. Also included is a fill plug made of high strength corrosion resistant stainless steel.

Perfect replacements 👍🏼
Size: CF11182&CA12051, Size: CF11182&CA12051
Perfect fit at an affordable price. Engine air filter is good quality, but the cabin air filter is way better than the stock one. They even include instructions.

Worth every penny!
Size: CF11182&CA12051
I have a 2020 Honda Civic Sport, and these filters fit perfectly. I was hesitant in purchasing because it said that its a frequent returned due to compability. Installation was a breeze after watching a quick YouTube tutorial, although it does come with instructions/manual. They look solid and durable. They came individually wrapped. I’m hoping they help with the odor and fogging issues caused by the old filters.
Honda service wanted to charge me $63 for the cabin filter alone, so this was definitely a much better deal. I would purchase again in the future.
The item ID that I purchase is CF11182&CA12051.
