Leaf Spring Perch & Plates (pair)

The Leaf Spring Perch & Plates set is the ideal companion to a Spring Over Axle (SOA) swap built on an Artec Modular Truss. Instead of clamping the axle with U-bolts, the top plates bolt through the perches to spread spring load across four bolts for a stronger, cleaner leaf mount.

Key Features

• Eliminates U-bolts by spreading spring load to four bolts rather than two
• Includes truss end caps for a seamless transition between Artec Modular Trusses
• Three leaf pin positions for one-inch adjustments forward or back
• 3/8" thick top plates and perches with 1/4" gussets
• Works with a variable axle tube diameter; grind off the small tabs to fit larger tubes
• Sold as a pair

Fitment & Compatibility

This is a universal fabrication component for leaf-sprung, Spring Over Axle builds. It is designed to integrate with the Artec Modular Truss system by way of the included truss end caps, so it pairs with modular trusses such as the 60 Rear Truss or the 14 Bolt Modular Truss. Additional Modular Truss Ends are available to complete the assembly.

Frequently Asked Questions

Why eliminate U-bolts?
The bolt-through top plates spread the spring load across four bolts instead of two, which increases strength and cleans up the spring-over-axle mounting.

Do these work with any truss?
They include end caps designed to transition seamlessly into Artec Modular Trusses, so they are built for that system rather than a generic truss.

Can I adjust the axle position under the spring?
Yes. There are three leaf pin positions that allow one-inch adjustments forward or back.

Will they fit my axle tube diameter?
They accommodate a variable tube diameter; you grind off the small locating tabs to fit larger axle tubes. Installation requires welding.
