I installed all mounts correctly on my 1998 Chevrolet K1500 but had serious issues. 1) The transmission mount is over 1/4" taller than the factory mount. This caused stress on my transfer case, causing it to leak. 2) Using these engine mounts caused the drivetrain to "clunk" when leaving off of the accelerator. I believe this is due to the fact that one needs to separate the halves to install which allows the rubber to move under tension. These mounts are not easy to install and most likely led to the aforementioned issues. I have removed them and installed another brand. The rubber material itself looks top notch but no attention to detail was paid on the actual dimensions and installation procedure. I really wanted to like these.

I used this when I pulled the engine and transmission on my 93' K1500 Blazer. I put in an LS engine and 2000-06 Trans. The trans mount is the same on a 4wd 6 bolt to 6 Bolt Adapter from trans to transfer case. Replaced engine mounts too. Good quality and easy to install when everything is out. Will work with original engine and trans. Just my application was a tad different.

Install was a bit of a challenge, but overall came out really good.

These are very nice bushings, but be ready for a tough install! I installed these all on a 94 Chevy K1500 4x4 with 350/5.7l and a manual trans. First tip is to compare the new and old trans mounts, there is an extra metal piece that would have made the new one way bigger and I did a search online and it seems others find that to be true and also did as I did and not install the piece. Next for the real work! The motor mounts, for whatever reason Chevy made getting them out a big hassle, I have an engine hoist so that part was easy but the long bolts are difficult to get to, particularly on the drivers side as the front diff and oil filter get in the way. I ended up using a socket/swivel/extensions and an impact gun and wrench to get it off and put back on. Then there are 3 bolts each mount to remove and there was no easy way for me, there are nuts under the frame that are very hard to get to and remove, I didn't have any help but if you can get someone to tighten or loosen it would make this job much easier. Read the instructions that come with the motor mounts as to how to reuse the old "clamshell", a drill press and vise make this job pretty easy. It took me about 4 hours to do it all, with 80+% spent on the motor mounts. In all for me I think it was worth it as the motor mounts were probably the original ones with about 20 years and almost 200k on them. My issue was a noise & perceived motion of the engine/trans during hard acceleration or high RPM shifting, which has diminished but I need more time to really evaluate the improvement.
