After hearing how this was an upgrade for the early 2000s GM trucks I finally bought and installed it on my 2001 GMC Sierra 2500HD 8.1L and it fits perfect with no modification needed. I replaced this along with the master cylinder and brakes work much better than a 2023 truck.

WOW! Amazing, the brakes stop my truck better than the day I drove it off the lot. Perfect fit on my 2005 GMC Sierra 3500. Recommend everyone upgrade their trucks!!! Watch You tube before attempting the change out. I did put one on a second truck. This time the transmission failed to shift. Although instead of drilling the shaft hole out 1mm, I disassembled the brake light switch and readjusted the contact,. One of three contacts in the switch, foreword most one. Now the throw is shorter and fixed the issue without drilling the hole. Just wear safety glasses as there is a spring inside the switch that may pop out and hit you in the face the first time you disassemble it. Seemed a bit overwhelming at first but, it was relatively easy once I got it apart. The brake light switch on the 2011 GM is a bit different than the 03-07 models. Very pleased with the result. I did order a second switch in case I failed, Now that extra sets in the glove box as a trophy reminder of the simple fix it was without drilling.

I ordered this for my 2007 LBZ Duramax. It fit perfectly. No modifications needed. If you cant shift out of park. Step on the break pedal with a rightward angle and you will be fine. Like an anti theft built in.

I installed this on my 03 sierra 2500HD. It fit perfect and the brakes feel so much more responsive than before. Like others have said, you may have to open up the hole on the shift that connects to the brake pedal. At first I did not but did in the end as I was trying to trouble shoot why my truck wouldn't come out of Park after everything was installed. Turns out I had damaged the brake switch when I was removing the 4 nuts under the dash. Be very careful with this switch and remove it fully so it does not get knocked around.Very happy with this product and would have been an easy install if I hadn't damaged the switch.Much cheaper than the direct replacement one too.

Product is straight from the junk yard, deceptive description. If you need an expensive rusty paperweight this is the product for you. Zero customer support, would strongly recommend you look elsewhere.
