Product Details
When you're working on heavy-duty trucks, especially those using "Z" blocks or other axle spacers from brands like Hendrickson, Freightliner, or Ford, you might run into issues with concentrated pressure points. These can actually crush or break caster wedges, which is the last thing you want when you're trying to get your alignment dialed in. That's where the SPC Performance HD Wedge Spacer Plate comes in handy. It's designed to spread that load out evenly.
This plate is 1/8" thick and comes in a pack of six, with each plate supporting 4" wide axle spacers. By using this spacer plate, you can prevent damage to your caster wedges and then use your preferred caster shim to fine-tune your alignment. It's also a practical way to make small adjustments to ride height from one side of the vehicle to the other, helping you achieve a more balanced stance.
