    Amazons fit guide is a little off on this one but this is a perfect fit for my truck. 07 Sierra classic LBZ with the 6 speed Allison.

    Fit my 2000 Chevrolet k3500 with a 4l80e transmission. Great design! Makes room to take pan bolts off without having to remove the mount. (Factory mount needs to be removed to remove pan).

    I installed this on my 2002 Chevy Silverado 2500HD Duramax/Allison pickup and it works great. Truck feels like it shifts better after replacing my stock rubber one with this poly mount.

    Bought this mount in January. Has been on for a month now. Notice that it is firmer. Easy to install. Comes with new hardware. Have a trans jack or floor jack and a piece of thick wood to cover the trans pan. Undo the bolts and lift the trans just enough to get the old one out. Install the new one. Lower the trans enough to start the bolts. Drop the trans and tighten the bolts. I bought Merchant Automotive engine mounts. When I install them. I will review those also.

    Installed on my 2005 gmc 3500 Dually 4x4 with Allison 1000 transmission. Took me 20 min to install. Very good quality. Took care of my shake on accelerating.

    Its a Tranny mount. I used same product line on the engine mounts. I have a vibration from nor changing this mount. These are superior to oem rubber mounts.

    Very well built and high strength neoprene rubber. My other transmission mount would always crack or break. This one has been in my truck for 2 years and I have put it through extreme use and had no problems problems!

The nature of this superior material, Energy Suspension"s Hyper-Flex, is the result of twenty plus years of experience working with and formulating polyurethane materials. Careful selection of material firmness or durometer is used for each specific application on the vehicle"s suspension and frame. The three most valuable reasons for using Energy Suspension"s Hyper-Flex components are performance, durability and appearance. Called "HYPERformance", Energy Suspension"s Hyper-Flex is performance polyurethane that delivers an amazing amount of performance to any vehicle that runs with it. Proven on the race track as well as the street, on and off-road, under the most demanding conditions. Over twenty years of positive customer raves have attested to that. Whether domestic or import, front, rear or 4WD, or old or new, all vehicles will achieve that level of performance that has made Energy Suspension the most asked-for name in performance polyurethane suspension components. Durable Hyper-Flex components do not rot or deteriorate from exposure to oils and undercar chemicals or atmospheric conditions like smog and ozone. Unlike O.E.M. rubber, Hyper-Flex components will not break down and deteriorate causing mushy handling and poor steering response. Certainly not what you want on your vehicle. And for improved appearance, Hyper-Flex components are available in red or black, to suit your needs for show or go.
