Brand: Longacre Racing Products
For the most accurate alignment, all four wheels should be level. These spacers are designed to be exactly the same height as the Longacre 79800 Turn Plates (Part No. LA7980, sold separately). This brings the rear wheels to the same height as the fronts to prevent errors.
Simply position the front wheels on your turn plates and the rear wheels on these spacers. Slip plates on the top allow the rear wheels to move freely as adjustments are made, avoiding problems caused by tire bind.
Sold in pairs (enough for both rear wheels).
