SAF ZFX40 Z-Frame Series

Axle Clamp Assembly

The axle clamp assembly features ¾” Grade 8 square U-bolts and one-piece top plate for positive U-bold alignment.

Equalizer Access

Crossbeam permits easy access to the equalizer.

High Strength Hold-Downs

High strength hold-downs secure the Z-Frame system to the trailer.

Pin Cage Design

Pin cage design enables easy removal of hold-down bolts. Permits entire slide / suspension system to be removed in minutes.

Qwik Release® Pin Pulling System

Patented Qwik Release makes slider adjustment safe, easy, and efficient. Qwik Release allows one person to reposition the slider, and eliminates the headache of bound-up pins. Standard on all HOLLAND sliders.

Hangers and Spring Seats

Hangers are welded at top and sides for maximum durability and performance. The spring seats are heat treated low alloy steel for longer life.

Black Armour™ Metal Protection

The Black Armour™ metal protection process, unlike a primer, paint or powder coating, chemically bonds with metal to form a protective skin that is impervious to water and anti-icing chemicals. BLACK ARMOUR™ is top coat compatible without pre-sanding and remains flexible to resist gravel impingement. If scraped, BLACK ARMOUR™ inhibits the spread of rust creep.
