These velocity stacks will fit Honda Shadow VLX and VT600 from 1988 - 1998, VT500C from 1983 - 1986, and Honda Shadow VT750 dual carb Motorcycles except pre-1998 VT750 dual carb models. They are made to fit the stock dual carburetors. They may fit other models or brands however we cannot speak to the fitment.

Dual Carb Velocity Stacks Will Fit:

• 1988-1998 VT600, VLX 600, Steed
• 1998 and up, all dual carb VT750 models- Spirit, ACE 
• 1983-86 VT500C

Fits If you remove the airbox on a Honda Shadow with dual carbs, the carbs will have a hard time creating enough negative vacuum to pull in a steady flow of fuel from the pilot and main jet. The solution to this issue... Velocity Stacks! They allow the carb throat to be lengthened enough so that the engine can maintain vacuum beyond the slide of each carb, as well as allow the air turbulence to be reduced, resulting in a much smoother delivery of air and fuel to your engine.

Includes: 

• Two Dual Carb Velocity Stacks
• Two Filtration Screens
• 6 Stainless Set Screws
• Allen Key for Set Screws

You will need to purchase the TJ Brutal performance tuning kit with your stacks to achieve the desired results. The kits you find online will not work with these! You can find the TJ Brutal performance jet kits HERE.

Please note: These will not fit the VT700 VT750's before 1998 or the VT800. 

Each stack comes with a metal mesh filter screen to keep out birds, cigarette butts, and small children. These don't even let sand through! The stacks function in all weather. Do not add any other filtration to the v-stacks!  Each stack is attached with 3 small sizes #6-32 set screws. Dual carb stacks come 2 to a set. 

To install, put the screen on the carb, then slip the stack on and tighten the set screws. We recommend using a locking agent such as loc-tite to secure the set screws.
WITH PROPER TUNING, THESE WILL NOT HARM YOUR BIKE, NOR WILL THEY ALLOW ANYTHING HARMFUL INTO YOUR MOTOR! 

These are not a PLUG-N-PLAY item!  You will have to tune your bike once you install these stacks. There's lots of good info on how to tune on our Support Page and YouTube videos explain the process pretty well. Our YouTube channel is TJBRUTALCUSTOMS.

They are perfect when installing aftermarket carbs. Your stock rubber intakes are not designed to support the weight your carbs without your stock airboxes installed, causing them to crack over time.
