These are Poly motor mounts that fit 2014-2018 GM2Kxx GM LT-equipped trucks including Silverado, Sierra, Tahoe, Yukon, Yukon XL, Suburban, Denali, and Escalade. They are a direct bolt up using factory hardware. These are laser cut 3/16″ steel fully MIG welded. All brackets will ship raw ready for your paint or painted depending on the options selected above. They match factory measurements so the engine remains in the same location as stock. Sold as a pair only since the driver side and passenger side are different. These are a solid piece of steel, there is nothing to wear out or need to be replaced. I would recommend solid mounts for 1500hp+ applications, or if you have a frame mounted turbo, otherwise the poly mounts are probably a more comfortable choice although these will work at any power level.

These are designed, manufactured, made with 100% USA materials by some guy in Alabama. Roll Tide.  Any imitations you see without the AFP logo are NOT authentic and will likely not work or fit correctly. I designed these from a high-resolution scan of a stock mount to make sure they mount correctly and without issues.

Mount Height: This is a new option I added that lowers the engine 1/2″ from the stock position. This is generally only for the serious racer that has a good reason to do this. Lowering more than 1″ will require a lot of work. The main clearance items will be the steering line fitting under the oil pan on top of the steering rack, and the crossmember behind the engine at the bottom of the oil pan. A 1/2″ drop should clear these fine, but modifications may be necessary on your particular truck. The 3 main reasons for wanting to lower the engine will be:

• Additional cowl clearance for large intake or intercooler
• Lower CG and better instant center position for the suspension
• Improves pinion angle with lowered vehicles since it will raise the exit angle of the transmission

Lowered mounts are only sold in pairs.

Installation note:
Do not overtighten the main center bolt. It uses a locking nylon nut and will not back off. Overtightening can compress the mount which may result in an increase in vibration. Snug is fine so the gap between the poly bushing and tabs is taken up, roughly 22ftlbs. The mounts are different left to right. The right (driver) side is taller/longer than the passenger side.

Note for 2014 model year vehicles: 2014 was the transition year between the LS (07-13) and LT (14+) engines for the trucks, however some SUVs did not go to the LT engine until the 2015 model. If yours is a 2014 please verify what type of engine it is and if you need the 07-13 mounts instead.

Note for SUVs: These generally work for 2015-2020 GM suvs like Tahoe, Yukons, Suburbans, etc. The 14-18 moniker is based on the truck years.
