Darlington Air Cleaner

Get rid of your bulky air cleaner and show off that H-D Engine! The Prism Supply Co. Darlington Air Cleaners were designed to achieve a clean, classy, and traditional look while maintaining maximum performance. These are beautifully machined from a solid chunk of 6061 aluminum and are available with either a polished or brushed finish. The internal venturi was designed to allow for maximum airflow. The mounting hardware for the cover is installed from the backside and gives that minimal look we all strive for.

With our combination of heavy and fine filtering elements, we can guarantee you’ll be keeping all that unnecessary crud out of your engine. If you ever are in need of a replacement filter element, those can be purchased here.

This compact kit is designed to be used on all H-D engines that use a CV carburetor or factory EFI units (excluding throttle by wire models)

Dimensions are as follows:

• 5.5” diameter
• 1.5” total depth

*Some basic jetting/ tuning may be required upon installation to maintain the correct air/ fuel mixture.

*When installing, it is recommended to use a carburetor support bracket.

Velocity Stacks - Honda Shadow VLX VT600 VT750 - Dual Carb - Gloss Black

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.

Velocity Stacks for EFI Honda Shadows - VT750

The velocity stack for the EFI Honda Shadows is finally here!  Each stack comes with a surgical-grade stainless steel filtration element. Each stack is attached to the throttle body over a stainless steel filtration element with 3 included set screws.

These will fit the following EFI models

VT750 Phantom
VT750 RS
VT750 Spirit only with EFI
VT750 AERO only with EFI 

Includes: 

• One Single EFI Velocity Stack
• One Stainless Filtration Screen
• 3 Stainless #6-32 Set Screws
• Allen Key for Set Screws

In most cases, you can put a stack on your EFI-controlled bike and the computer will adjust to the new changes within a ride, making this intake an easy plug n play part.  However to get the most out of your intake upgrade and to really see a step up in performance then you may want to look into an aftermarket EFI controller. 

You will need to remove your stock air box to install this velocity stack and either plug your PAIR valves or use a set of TJBC PAIR block-off plates to block them off.
