Do 4 link bars have to be parallel?

A parallel 4 link fits most trucks better because the fuel tank is usually right in front of the axle, inboard of the frame. A parallel is sometimes easier to install because the link bar frame mount is one piece instead of two… less time in placing and welding the upper bar mounts.

What is better 3 Link or 4 Link?

3 link requires a panhard rod or trac bar to keep the axle from moving left to right. The 3 linl is easier to fit around engine/exhaust/etc… 4 link with dual triangulation done well will locate the axle without panhard rod but is sometimes a bear to fit the upper links and the frame end of lowers.

How long do 4 link bars need to be?

Length should be two-times the wheel travel you expect; longer and flatter links generally perform better. A 36”- 42” link is commonly used for rigs with a wheelbase that is long enough to accommodate the size. Longer links are easier to bend, no matter which material is used.

Does a 4 link need a Panhard bar?

This is what keeps the rear axle centered under the vehicle. There is no need for a separate lateral locating device. Conversely, with a parallel style 4-link, all bars are parallel to each other and the vehicle centerline. A “Panhard bar” or other separate device is required to keep the axle centered.

Is a 4 link suspension good for road racing?

4 link seems best for cruising (because it is free from the donor if you go that route) and drag racing. 4 link can bind in certain cornering situations (autocross or racing type). For cruising it is fine. Good for a drag race type car.

How long should lower links be?

What is anti squat?

Anti Squat is a term for suspension engineers to determine how much the suspension mechanism itself is resisting suspension compression. Anti-squat is suspension’s mechanical resistance to compression due to forces from the engine (when on a bicycle human is the engine).

How long is a 4-link rod end?

(3/4-16 Threaded 4-Link Rod End has 1.950” threaded length) 1.950” total threaded length – .750” minimum threaded into tube – .4375” thick jam nut = .7625” is the maximum thread sticking out from the jam nut allowed, and still have .750” threaded inside the tube

Can I build my own 4-link bars?

Since not all applications will have a kit available, Speedway Motors sells the parts needed to build your own 4-link bars. My project truck is one of those applications where I would have to do some fabrication to get exactly what I wanted. Here’s a guide to help you if you ever need to build your own links of any kind.

Is a triangulated 4-link suspension any good?

A Triangulated 4-Link has inherent design flaws as the pinion angle changes as the suspension travels up and down, which can lead to poor cornering, especially on uneven pavement. Coilovers OR Airbags, your choice. Coilovers are the most popular for everyday cruisers and Airbag kits are for those who want to lay their vehicle on the ground.

How much thread do you put inside a fishing rod?

The general rule is that you must have at least as much thread inside the tube as the diameter of the threads. So in my case using 3/4-16 rod ends, I must have at least 3/4” of an inch threaded inside to remain safe.
