These spacers help with brick flow, better cooling, and less heat soak for all TVS, Radix, and M/MP series blowers. We make these that will fit Square, Cathedral, and 2650 Jackshaft "bottom tubs". Anything from 1/4" to 1.5" in height.
Hardware is included on both billet and phenolic versions as long as we are supplied with bolt lengths before we ship. Gasket material and O-rings are only supplied with the billet versions, as its not used in the phenolic and RTV is used to not compromise the material. 2650 spacers will come with longer alignment pins as well.
See "Custom Modifications" for more options with N2O or Alky/Snow nozzle additions. Please note: The thinnest material for additional ports is 5/8" in billet and 3/4" in phenolic.
Some bottom tubs come with built in fuel rail mounts, and will not require injector spacers. For all other fuel rails that are mounted to the upper tub, you MUST get injector spacers that are the same height as the spacer you are using.
To verify what tub you have, please use the picture below. The tubs are not interchangeable. We are also limited to a 150mm bolt length on the main 10 bolts for the tub. We cannot go longer than that, which will normally support all heights of the spacers, but to be sure, pull 1 bolt out and measure it, and we can make sure we include the correct hardware. Again, PLEASE let us know when making your order or before your order ships on the length bolts you need. Also, some tubs use 2 small plastic "bumpers" to hold up the brick, we can supply these if needed, IF we have the dimensions before your order is shipped.
These are a non-stocked item and are made to order. As with any custom part lead times can vary. Please contact us if you have a time constraint. All orders ARE NON REFUNDABLE AND NON RETURNABLE due to material availability and ordering process.
