Longacre 79751 Turn Plate Spacers with Slip Plates (Pair) Heavy-Duty Aluminum

When performing a precision chassis alignment on the ground, the front wheels must be placed on turn plates so they can swing freely. However, doing so raises the front of the car, throwing off the chassis rake and ruining the camber and caster readings. The Longacre 79751 Turn Plate Spacers with Slip Plates are the mandatory solution to this problem.

Designed specifically to be used in conjunction with Longacre's Aluminum Turn Plates (PN 79800), these spacers are exactly 1-inch thick. Placed under the rear wheels, they bring the entire vehicle perfectly back to level. Crucially, these aren't just solid blocks of aluminum; they feature integrated, free-floating slip plates on top. As a mechanic adjusts the suspension or bounces the car to settle the chassis, the rear tires can slide laterally without binding on the shop floor, ensuring absolute accuracy in the setup numbers.

Key Features

• Perfect 1-Inch Height Match: Machined to be exactly 1.000" thick, perfectly matching the height of Longacre 79800 turn plates to maintain a level chassis for accurate geometry readings.

• Integrated Slip Plates: The floating top surface allows the rear tires to move sideways as camber and toe adjustments are made, completely eliminating suspension bind that would otherwise give false alignment readings.

• Heavy-Duty Aluminum Construction: Built from rugged aluminum to support the heavy rear-weight bias of dirt late models, stock cars, and heavy track-day vehicles without deflecting or crushing.

• Complete Rear Axle Kit: Sold as a matched pair, providing everything needed to properly support both rear wheels during a ground-level alignment.
