Fixture Blocks

With each purchase of a MillerBuilt “Weld-On” Hybrid Full Floater kit, the appropriate fixture tools to assist with your installation will be made available to you for FREE via the MillerBuilt tool “Loan Program” (for details read the Q&A at bottom of this page).  The MillerBuilt fixture blocks are precision machined from 6061 aluminum then hard black anodized for maximize durability. The proper hardware is also included so you can get right to work! Fixture pieces and hardware are also available for purchase.

Kit Includes:

  • (2) Precision Machined Fixture Blocks
  • (1) Hardware Mounting Kit

PRICED AT – $350.00 pair

The fixture blocks are designed to fit 1.500” diameter straight bars. MillerBuilt recommends the Mittler Bros 1.500” straight bar. You will need the Mittler Bros bar or an equivalent in order to correctly complete your installation.


Depending on who will be performing your installation, check with your local fabricator/shop as they may already have a 1.500” straight bar. If you do need a bar, the bars can be purchased/shipped most cost effectively through Summit Racing.

MillerBuilt also HIGHLY recommends this handy tool from Moser that accurately assists with indicating were you will cut your axle tubes in order to obtain your desired overall housing width with the correct pinion offset for your application.

The fixture blocks feature a flat machined area to help accurately obtain the desired brake caliper “clocking position”. The machined flat surface simulates the plain/angle your caliper will be at once the caliper bracket and caliper are installed. Two steel dowels have been positioned within the machined flat surface to accommodate a magnetic based angle finder to help free your hands while tack welding the MillerBuilt Floater Ends to your axle tubes…

The fixture blocks have been designed to simulate the overall thickness of the SKF Hub Bearing Unit and E-brake Backing Plate allowing you to quickly check your overall “Hub Bearing Unit Flange to Hub Bearing Unit Flange” overall width without disassembly of the fixture blocks, and assembling of actual Hybrid Floater kit components… This saves time!
