    Morning everyone,

    I just installed the Cobb RMM and I wanted to get feed back if I installed it correctly. My biggest concern was the the bolt on the engine side doesn't thread completely through like it does in the rear. I drove around the block and everything felt tight. First and second gear shifts feel solid. Thank you in advance for your feedback.

    looks correct to me. Did you torque the bolts to spec? I added a dap of blue Loctite on the bolts when I did my install.

    As an FYI, 1.5x thread diameter for engagement is considered to be good. The bolt not sticking out of the transmission boss isn't a concern given the amount of thread engagement.

    BRGT350, thank you for your input. Everything torqued to spec, with an extra ump for security. I used red Loctite on the bolts. I guess now time to have some fun...

    Different issue, but did yours come with a washer? This washer did not come with mine, so I had to request it from Cobb. It goes between the front (non-engine) bolt and the RMM. I'll see if I can find the install instructions.

    Look for bluebombers install on the other, forum ( It talks about the washer. The Cobb install I downloaded did not show this washer.

    Where did you guys get the torque specs? What are they if I may ask? The instructions said nothing about torquing to spec. I just installed mine and the vibrations were ungodly. Did not feel right at all. I took it for a spin and it just felt wrong. I'm waiting til morning to call manufacturer.
