5.7 Hemi Rocker Arm Torque Specs
The 5.7 Hemi engine is a V8 engine that was produced by Chrysler. It was first introduced in the 2005 model year and was used in a variety of vehicles from that automaker. The Hemi engine is named for its hemispherical combustion chambers, which are shaped like half of a sphere.
The 5.7 liter designation refers to the total displacement of the engine, which is 5,654 cubic centimeters.
If you’re doing a Hemi 5.7 rocker arm swap, you’ll need to know the torque specs. Here they are: – Outer bolts ( between rockers ): 55 ft-lbs
– Inner bolts ( attaching rockers to shaft ): 35 ft-lbs – Shaft bolts ( attaching shaft to cylinder head ): 25 ft-lbs Make sure to use thread locker on all the bolts, and be careful not to overtighten them.
If you do, you could damage the threads or break the bolts.

The Importance Of Rocker Arm
The rocker’s arms are the small pieces of metal at the bottom (or sometimes top) of a car engine that connects to the crankshaft and camshaft. They move the pistons up and down, which turns the gears in your car. The main job of these arms is to convert mechanical energy into rotational motion, which powers your vehicle.

5.7 Hemi Rocker Arm Installation
If you have a 5.7 Hemi engine, chances are good that you’ll eventually need to replace the rocker arms. Here’s a detailed guide on how to do just that.
The first thing you’ll need to do is remove the old rocker arms.
There are four bolts that hold each rocker arm in place, so use a socket wrench to remove them. Be careful not to drop the bolts into the engine!
Once the old rocker arms are out, it’s time to install the new ones.
Start by attaching one bolt finger-tight, then use a torque wrench to tighten it to 18 ft-lbs. Repeat this process for the other three bolts, and then double check that all four are tight before moving on.
Now it’s time to reinstall the pushrods.
First, lube up each pushrod with some engine oil, then insert them into their respective holes in the cylinder head. Be careful not to cross-thread them!
Finally, it’s time to reinstall the valve covers.
Put a little bit of RTV sealant on each side of the gasket, then bolt everything back in place using your socket wrench.
5.7 Hemi Rocker Arm Bolts
If you own a 5.7 Hemi engine, then you know that the rocker arm bolts are an important part of the engine. These bolts help to keep the rocker arms in place and prevent them from moving around. However, over time these bolts can become loose and need to be tightened.
If you’re not sure how to do this, don’t worry – we’ve got you covered.
In this blog post, we’ll show you how to properly tighten the rocker arm bolts on your 5.7 Hemi engine. We’ll also provide some tips on how to keep them tight so that you don’t have to worry about this issue in the future.
Let’s get started!
First, make sure that the engine is turned off and cool before starting this project. Next, locate the rocker arms – they should be on either side of the cylinder head (shown in Figure 1).
Once you’ve found them, use a socket wrench to remove the bolts that hold each rocker arm in place (Figure 2).
Now it’s time to reinstall the rocker arms with new bolts. Start by threading one bolt into each hole until it’s finger-tight (don’t use the socket wrench yet).
Then, alternate between tightening each bolt a little bit until both are snug – but don’t overtighten! Finally, use your socket wrench to give each bolt a final quarter turn for extra security (Figure 3).
That’s it – you’re all done!
Just remember to check your work after a few miles of driving just to be safe. With proper maintenance, these newly installed rocker arm bolts should last for many years without issue.

How Tight Should Rocker Arm Bolts Be?
The rocker arm is a critical component in the valve train of an internal combustion engine. Its function is to transfer force from the camshaft to the valves, and it is under a great deal of stress while the engine is running. Because of this, it is important that the rocker arm bolts be tightened to the proper specification.
The tightening torque for most rocker arms is between 15 and 20 ft.-lbs. Some engines may have different specifications, so it is important to consult your service manual or engine builder before proceeding. It is also a good idea to check the bolt periodically during operation for tightness.
Over-tightening the rocker arm bolts can cause problems such as distortion of the rocker arm body or cracking of the mounting bosses. This can lead to premature failure of the component. Under-tightening the bolts can allow them to come loose, which can cause noise and vibration issues as well as damage to other components in the valve train.
How Do You Torque a Rocker Arms?
Assuming you would like tips on how to torque rocker arms:
One way to torque rocker arms is as follows:
-Using a small socket, rotate the pushrod until it is horizontal and tighten the jam nut.
This will be your zero point.
-Now take your big socket and wrench and place it on the top of the rocker arm stud.
-Slowly turn the wrench clockwise until you reach 20 ft/lbs of torque.
Be sure to check your owner’s manual for specific numbers. Do not overtighten!
-Once you have reached 20 ft/lbs.
, back the wrench off half a turn and then retighten to 20 ft/lbs again. This will help prevent galling of the threads.
How Do You Torque a Ls1 Rocker Arm?
If you have a LS1 engine, then you know how important it is to keep the rocker arms in good working order. But what do you do when it comes time to torque them? Here are some tips on how to torque a LS1 rocker arm:
First, make sure that the engine is at operating temperature before beginning. This will ensure that the rocker arms are properly lubricated and will allow for more accurate torque readings.
Next, use a quality torque wrench to snug down the bolts holding the rocker arms in place.
Be careful not to over-tighten these bolts, as doing so could damage the threads or strip them entirely.
Finally, once all of the bolts are tight, give each one a final turn with your hand to make sure they’re all seated correctly. Then, recheck your work with the torque wrench to ensure that everything is where it should be.
What Torque is the Rocker Arms on Chevy 350?
When it comes to the torque on Chevy 350 rocker arms, there are a few different things that can come into play. For example, the camshaft size and type can affect the amount of torque that is required. Additionally, the heads and intake manifold will also play a role in how much torque is needed to properly operate the engine.
In general, however, it is safe to say that most Chevrolet 350 engines will require somewhere between 65 and 85 ft-lbs of torque on the rocker arms.
Conclusion
If you’re working on a 5.7 Hemi engine, you’ll need to know the torque specs for the rocker arms. Here are the specifications: Rocker Arm Nut: 22 ft-lbs
Pushrod Tip to Rocker Arm Stud Nut: 30 ft-lbs Make sure to follow these torque specs when working on your 5.7 Hemi engine, and you’ll have no problems!
