Fits: 2001 thru 2019 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM/LML/L5P Duramax Diesel w/Allison 1000 Transmission & Deep Sump Pan Filter

*Scratch & Dent, a few scratches on the surface. Sold as is, no returns, refund, or warranty*

DmaxStore's Allison filter lock will reduce cavitation due to lack of seal at the filter and also will hold the filter securely in place when installed. 

Notes:

• Will not work with deep sump pans that have built-in filter locks
• Our filter lock reuses the bolts from your valve body
  
• You will reuse the factory bolts that are already on the valve body and torque the bolts down to 100 lb-in.
