TwinLock™ Design

FW35 - Reliable lock performance for successful coupling time-after-time.

FW35 TwinLockdesign immediately captures the kingpin preventing kingpin impact bounce out for quick and reliable coupling.

  • Exclusive TwinLockdesign is your BEST BET TO REDUCE FAILED COUPLINGS..
  • Add another level of coupling safety with the optional ELI-telock indicator feature.

Superior Lock System Design

1. High Coupling Protection.
Lock system protects against coupling at an improper height.
2. Much Greater Kingpin-to-Lock Contact.
Provides driver with a clear visual indicator when lock mechanism is properly closed around kingpin.
3. Forged/Cast Steel Locks.
Rear lock is forged, hardened, and machined steel. Front lock is machined and hardened wear-resistant alloy.
4. Precision Machining of lock mechanism/kingpin interface.
Provides a safe, reliable coupling to reduce the possibility of coupling failure due to the unique fifth wheel lock jaw technology.


Trust your fleet to the industry’s proven and trusted leader for over 100 years.

  • The Industry’s Only Performance Guarantee


1. TwinLock™ Design
Quick coupling action of the exclusive TwinLock™ design increases driver confidence.
2. Visible Lock Indicator
Provides driver with a clear visual indicator when lock mechanism is properly closed around kingpin.
3. Articulation Pocket NoLube™ Liners
Reduce maintenance and assists in longer top plate life.
4. Cast Steel Top Plate
Optimized casting process yields a higher maximum strength to weight ratio.
5. EZ-Grip™ Drop Release Handle
Prevents damage to handle when mis-coupled – preventing costly downtime repairs.


FW35 Series ELIte™

Electronic Lock Indicator Technology Enhanced system is an optional LED coupling-assist feature for the FW35 Series HOLLAND Fifth Wheels

Flashing red lights indicate a failed attempt.

Solid white lights shine brightly on the lock, providing illumination of the fifth wheel
lock to assist driver inspection.

This exclusive HOLLAND brand innovation provides drivers with LED light indicators for quick recognition of a successful or failed coupling attempt.

Driver and Fleet Benefits are measured in the reduction of incidents involving non-coupled trailers and an increased level of driver coupling confidence!

Air Release

FW35 Series Optional Air Release

HOLLAND FW35 optional In-Cab Air Release (ICR) system improves productivity and helps protect the driver. The ICR system allows drivers to quickly and safely uncouple the fifth wheel using an in-cab switch.

The Fleet Advantanges

Driver efficiency is raised:
The HOLLAND Air Release system helps drivers stay on schedule … more time on the road, less time outside the cab.
Driver safety on the job is improved:
Less strain, fatigue, and the potential for injury, especially when in bad weather or when access to the release handle is difficult.
Driver comfort improves performance:
Hands and clothes free of grease and grime mean less time with unnecessry cleanup and more time getting the job done.

How it Works

1. Set the tractor parking brake to activate the system.
2. Push (or pull – depending on installation) the dash-mounted button to activate a pneumatic cylinder on the fifth wheel to open the lock.
System allows for manual release operation, if necessary.


Reduced-Grease Operation

Reduce fleet maintenance costs while retaining fifth wheel performance. HOLLAND LowLube top plates feature durable, replaceable lube plates, and grease-free articulation pocket liners. Now only the fifth wheel lock mechanism requires grease.

How it Works

1. Advanced Lube Plate Design.
Polyethylene material is molded around a honeycomb pattern steel reinforcement plate to create a wear, peel, and warp resistant lube plate.
2. Replaceable Lube Plate
With easy access lube plate fasteners. Available from SAF-HOLLAND Original Parts.
3. NoLube™ Articulation Pocket Liners.
Reduce maintenance and prolonged top plate life.

FW33 LowLube Top Plate

Standard and Moderate-Duty

LowLube technology that requires grease ONLY on the lock mechanism.

Performance Guarantee

What does Performance Guarantee mean to you?


6 Years

The HOLLAND FW35 Series is guaranteed for 6 Years / 600,000 Miles to provide maximum operation performance.

In the unlikely case of wear requiring lock mechanism replacement, SAF-HOLLAND will cover the cost of parts, labor and freight.*

Mounting Options

FW35 Series Mounting Options for Nearly Every Application!

Mounting options with infinite configurations!

Warning, large download!


HOLLAND stationary fifth wheel mounts are designed for applications where the axle loading, kingpin setting and vehicle combination length all remain constant throughout the fleet.

Stationary fifth wheel mounts are generally lighter weight and lower cost than sliding mounts, however, they do no offer the application flexibility of a sliding mount.

For: Standard Duty Applications


HOLLAND Integrated Low-Weight Slider System (ILS) utilizes a lighter weight, no welding modular design to provide significant weight savings and easy height change.


  • Lighter weight without sacrificing durability and reliability
  • Single-piece, bolt-on cast bracket (low weight, easy replacement)
  • Two-piece side cushioning “up-shock” bushings
  • Slide-on (No weld), repositionable bulkhead fitting bracket
  • Same air cylinder location on all heights (includes “quick-connect” fittings)
  • 2” slide increments
  • Available for both inboard and outboard mounting

For: Standard Duty Applications


For applications where articulation is provided by the trailer, the no-tilt high strength steel cast design provides reliability in both articulation directions, and both push and pull vertical strains.

NO-TILT Available for: FW35, FW33

For: Standard Duty Applications


The HOLLAND Severe-Duty Slider System for Fifth Wheels is the highest capacity slider system in the industry.


  • 70,000 Lb. vertical and 200,000 lb. draw bar pull capacities*
  • 8˝, 9˝, 10˝, and 11˝ bracket heights
  • 12˝, 24˝, 36˝, 48˝, 60˝, and 72˝ slider travels.
  • 2˝ slide increments for positioning versatility
  • In-cab air slide release control
  • SDS modular design is service friendly to allow the changing of fifth wheel heights or adding an optional convertible No-Tilt top plate.

Available for:

*Limited to Top Plate MAX Capacity

For: Severe Duty Applications


The world’s only mounting system designed to relieve the force created in rigid trailers on uneven terrain.

The patented design cradles the fifth wheel and provides side-to-side compensation. This allows more flexibility between tractor and trailer and reduces torque and twist transfer through the fifth wheel.

Available for: FW35, 33* and 70

*FW33 for Moderate Duty Applications

For: Severe Duty Applications
