Depends on the location of the added weight...., "forward" of the TV's rear axle will add a percentage of the added weight.
I know that on most GM Trucks and SUV's if you exceed the TV's unhitched steering axle weight the suspension stops will be compressed creating a rough ride.
I wouldn't use 4-links under tension if it produces an "over-weight" on the steering axle...., stay with 5-links (3.400lbs).
The reason your WDH installation instructions state "minimum 4 links" is because the Pro-Series (Reese, Draw-Tite, etc.) has a straight (flat) spring bar tail and is not considered a heavy duty WDH. Most heavy duty WDH's (round & trunnion) have a radius at the spring bar tail that lowers the location of the connecting chain link, and I believe the dimensional relationship of spring bar to ball mount may differ a little as well...... these installation instructions (Reese, Draw-Tite, etc.) state 5-links minimum. Follow the installation instructions that came with your WDH, going below the recommended chain links under tension will cause the spring bar tail to come into contact with your TT's A-frame during TV turns.
Hope this helps.
