These rocker arms are made of outstanding stamped steel, as the name implies. This improves the pieces’ strength and longevity. As a result, stamped rockers operate differently from roller rockers. Why? Because the stud protrudes through a slot and finds the rocker.

These rocker arms have a longer pivot slot, which is another distinctive characteristic. This is why you can install a camshaft with a valve lift of up to 0.55.

In the valve stem and valve train, these roller tips are developed to decrease wear and friction. Because of the reduced friction, the horsepower is enhanced by 10 to 15 horsepower.

16 pivot balls, self-locking grains, and rocker arms are included in this set for your convenience. A 1.5 ratio and a 3/8″ stud diameter characterize each of the rocker arms. Because of this, they can be used with most SBC engines, including the 262 to 400 designs.

Basic Factors You Need To Consider Before Buying The Best Ls1 Trunion Upgrade

It is significant for you to know about the vital features of the best ls1 trunion upgrade before deciding to buy one. To successfully choose the best ls1 trunion upgrade, you need to take the following information into account.

As a roller rocker, its job is to keep the lifter moving upward while keeping the valves open with the assistance of pushrods. In order to open the valves, the roller rocker arms guide the pushrods in a descending position. Rocker arms come in a variety of shapes and sizes, depending on the material used in their construction.

Stamped steel, powdered metal, and die-cast aluminum are just a few examples. Moreover, all of these materials are extremely durable and resistant to scratches and environmental damage. On the basis of this, you should take into account a lot of things before buying the best unit for yourself.

Ls1 Trunion Upgrade

Fabrication Material

Object performance is heavily influenced by the materials used in manufacturing. If you want your device to last as long as possible, it’s important to pay attention to this factor. In this regard, modern roller rockers use a wide variety of materials. Some units are made of steel, while others have aluminum bodies.

Similarly, powdered metal is very popular in some areas, as it adds durability to the system, protecting it from damage and scratches. Before making a decision, you should thoughtfully take into account your needs.

A variety of materials has been used to create roller rockers. Die-cast aluminum, powdered metal, and stamped steel are the most commonly used materials. These additives are extremely durable enough to withstand a wide range of environmental stresses and strains.

All of the above contribute to the longevity of your unit. High lift ratios and high valve spring pressures require long-term reliability.

A stiff product is still the way to go. The performance of the rocker arms will be improved as a result. To boost the unit’s stiffness, you can use heavier materials, such as chrome steel.

Ls1 Trunion Upgrade


The arm ratio is another essential aspect that can have a significant impact on a rocker arm’s capabilities. You can increase valve life by increasing the arm ratio without having physical interaction with the internal parts such as the camshaft, by increasing the arm ratio. Due to this, you should look for designs with a higher arm ratio than those with a low rocker arm ratio.


In addition to the arm ratio, a stiffer device should be purchased. As a direct result of stiffness, you’ll be more productive. Use a heavier production material, such as chrome steel, to boost the stiffness of your previous item. Chrome steel has a higher potency density than aluminum and other metals, making it a better option for stiffening. As an alternative, a rocker’s holding match can be used to boost the rigidity of the system.

Ls1 Trunion Upgrade

Large bearings and roller tips

It’s also a good idea to look for tools with big bearings and roller tips. Reduced friction is directly related to lower oil temperatures, and these substances help to reduce friction. High horsepower and better vehicle response are also benefits of low oil temperature, according to experts. As a result of these aspects, a roller arm provides the best efficiency output possible.


Users’ decisions are also influenced by the cost of a product. Unbelievably, despite its impressive characteristics and high output, you might want to think twice before buying an item if it is extreme. Human instinct dictates this, and there is nothing wrong with it. Finally, you have to consider your budget and the fact that you have to buy a lot of other things. We recommend looking for cost-effective yet high-performance alternatives instead of spending a lot of money on high-priced items.

Ls1 Trunion Upgrade

A single intake or exhaust rocker arm can cost anywhere from $15 to $60, relying on the vehicle.

Costing between $100 and $500, rocker arm kits involve other essential parts like guide plates and pushrods and maybe a better option if you are confident that you can substitute the rocker arms on your own with no help from a professional.

When the rocker arms fail all at the same time, it’s a good idea to replace them at once. As a result, full kits are the most popular option.

In addition, because rocker arm maintenance is a time-consuming process, hiring an auto mechanic or car dealer to do the job can be expensive. Depending on the vehicle, you can expect to pay anywhere from $500 to $1,500 (parts + labor).

A large portion of the cost is labor, as it can take a long time to get to the parts you’ll need. There is a possibility that taxes and fees will increase the total.

Is a trunion upgrade expensive?

As a result of their exceptional characteristics and high-quality output, roller rockers are well worth the investment! For the most part, rockers are known for their ability to reduce friction and provide additional power to a vehicle’s engine. As a result of this, oil temperatures are lowered, which can help improve vehicle response. As a result, you must give them a try.

Are there different types of rocker arms to choose from?
