Most common rod ends are the 3/4″ shank necked down to 1/2″ thru bolts, this is what most of your 4 link brakets are using….
How long should 4 link bars be?
18″ is ideal for your setup.
How long should the 4-link bars be on a drag car?
The instant center length can actually affect the overall (race car + driver) reaction time. Bickel states that if your reaction times are good, a long IC point (50-60 inches is generally more desirable than a short one (50 inches or less).
What is the advantage of a 4-link suspension?
The benefits of a four-link over a simple leaf-spring suspension include controlling axlewrap, better departure angles, controlling axle path, and reducing the uncontrolled variables of axle movement down to just spring rate and shock valving.
Does a 4 link replace leaf springs?
4-Link Swap: A Smart, Bolt-In Upgrade for Your Muscle Car or Truck A 4-Link is one of the best upgrades you can make to your leaf spring-equipped muscle car or truck. Invented in the 1700s, leaf springs are a tried and true suspension medium.
What’s better 3 Link or 4 Link?
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.
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 anti-squat on a 4-link?
What is Anti-Squat? Anti-Squat is an engineering term which describes the 4-Links likely performance under acceleration. 4-Link settings with less than 100% Anti-Squat are likely to squat under hard acceleration (rear of car drops), and “hit the tires more softly”.
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.
What type of suspension is best for off roading?
Shock absorbers are ideal for off-roading, located on the opposite sides of the axle. One in the front and one behind will lessen the amount of axle tramp, which is a fast up and down motion of the rear axle caused by quick acceleration. The addition of sway bars controls body roll of the truck.
What is better coil springs or leaf springs?
Leaf springs are much sturdier in comparison to coil springs. They’re capable of handling much highest loads with less deflection than coils, trucks with leaf springs are also easier to raise or lower.
Is a 4 link suspension good for road 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.
Are leaf springs better for off roading?
Despite the shift toward coil springs, there are still many advantages to using leaf springs. Their simplicity, strength, and reliability make them great for off-road and commercial applications. They aren’t without their disadvantages, though.
Will new leaf springs improve ride?
Many thin leaves mean that each leaf can have a lower spring rate, which results in a softer ride. A spring pack with many thin leaves is thicker overall than one with a few thick leaves. That is a good thing in a spring-over application since the main leaf is flatter giving a better ride.
What’s better than leaf springs?
Coil spring suspensions offer more range of suspension movement, and allow the user a wider tuning envelope through the suspension range than leaf springs. Practically all high performance applications use coil springs where possible and if the budget permits.
Does panhard bar length matter?
During chassis roll a short panhard bar changes its angle, hence handling, more radically than a long panhard bar. Consequently, handling can become inconsistent if the panhard bar is too short (20″ minimum length is recommended).
What is a 4 link lift?
“Radius arms or 4-links are basically just the way the front diff or rear diff is held into the vehicle,” explains Naugle. Those arms help determine stability and control—and we don’t need to tell you how important those are out on the trail.
What is better 4 link or ladder bar suspension?
A 4-link is definitely superior to ladder bars. However, a 4-link is only superior in application if you are willing to invest the time it takes to sort it out. A ladder bar has two or three adjustment holes that actually work; a 4-link might have 50!
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).
What is the best weight distribution for drag racing?
Front Engine, Rear Wheel Drive
With front engine RWD production cars for racing, at Racing Car Technology we find we can still get good balance with weight distribution between 53% front weight percentage and 47% front weight percentage.
