What’s New At T-Man
m8 Bottom End Service
T-Man’s Bottom End Service is the premier choice for your high-performance big cubic inch motors or STD rebuild Harleys. With our proprietory scraper system and reed vavles, we aim to bring you the best service possible while also ensuring durability and reliability.
T-Man No Loss Air Cleaners
The T-Man No Loss Air Cleaner is the last air cleaner you will ever need! These are available for Twin Cam and Milwaukee 8, and we also have our V24 available for the newer ’24+ models. These feature a high-quality filter element made by Green Filter. This maximum flow filter allows you to run our air cleaner and not lose any HP or TQ, hence the name “No Loss.” For more info, click the link below.
T-Man Camshafts
T-Man offers a variety of camshafts for your Evo, Sportster, Twin Cam or M8 motor. We have bolt-in cams if you are looking to just do a cam upgrade on your stock bike, but we also have high compression cams for the customer who is looking to build up their bike to the higher cubic inches and wants big performance! Take a look at our cam selection and check out some of our results on the dyno charts page.
