Great service from helpful and knowledgeable staff.
Ordered on the 26th of March Didn't ship until late on the 28th its now the 3rd of April I still haven't received it Thanks to the Awful USPS Guess i'm disappointed all around
My go to place for my L5p maintenance kit. Fast shipping
Been reading issues with Allison and hailing heavy loads as I do. I bought this to try to alleviate any issues. Price was competitive. Took 45 min to install. Hard to findable over trans and transfer case into where it needed to go. Be patient you'll get it. All done I hope it foes what it was built for. Dirty hooker does not provide any install instructions . There are youtube instructions from other vendors Was basically just looking for any tips for easier and quicker install.
They've got all the parts you need. Customer service was great! Shipping is just stupid expensive
Prompt service, great communication on order status
