SBC is one of the most popular V8 engines for racers, truck drivers, and performance seekers. All thanks to their incredible performance as well as their small and lightweight nature.
These engines generate good torque. Thus enabling drivers to take off quickly from a standstill.
Chevrolet first produced the Small Block Chevy engine in 1955 as a 4.3 liter (256 cubic inch) engine.
Today, SBC engines are available in various sizes ranging from 265 – 400 cubic inches. Most Chevy trucks and cars you see out there run on 305’s and 350’s models.
The original design of the SBC had some drawbacks though! Many flat surfaces meet with other flat surfaces. Thus resulting in unnecessary friction in the valve train and decreased horsepower. The best roller rockers for SBC will help you solve this issue.
Roller rockers move the pushrods downwards and redirect the lifter’s motion. On top of that, they enable the valve spring to shut the valve.

In total, this set comes with 16 rocker arms, 16 pivot balls, and 16 self-locking nuts. Let’s check out their incredible features!
For starters, each rocker arm has a specially designed roller tip and fulcrum. For this, they create less friction as compared to the sliding factory models.
For this reason, the engine experiences lower oil temperatures and increased horsepower. With this set, you can increase your SBC’s horsepower by about 10 -15 HP.
You’ll also love the unique appearance and construction of these pieces. This is because they’re crafted from aluminum. Thus giving the set good strength and increasing its durability.
Besides, aluminum has less overall weight. So, regardless of the rocker arms having a larger-than-stock body, they’re easy to carry around.
Another notable feature of this system is that it includes snap rings. These rings hold and lock the bearings and trunion in place.
As for computability, this set works with most SBC engines out there. To be precise, it’s ideal for use in 1955-1986 262 to 400 small body Chevy engines.
This outstanding set is generally intended for racing purposes. It’s designed to be more durable, and stiffer. Moreover, it can give your Chevy an added valve lift.
Not to forget that it allows it to withstand the challenges of a performance application.

For that reason, they’re much stronger than stamped steel or die-cast aluminum. All these factors help the unit to minimize rocker arm flex.
Similar to the Assault Racing rocker arms we’ve looked at above, these pieces are CNC machined. This enables them to accommodate retainers as well as larger valve springs. The finishing, however, is done by hand.
One thing you need to note about these rocker arms though is that they don’t have a self-align system. Therefore, you’ll need pushrod guide plates to support the rockers.
You can use it in Chevrolet 262 to 400 engine models designed in 1955 – 1986 and 1987-2000.
Putting that aside, the roller tips are made up of heat-treated Cr40 steel. These tips minimize scrubbing and reduce friction. This providing additional horsepower to the stock rockers. On top of that, the unit has an internal oiling system to ensure durable performance.

As the name suggests, these rocker arms are made up of superior stamped steel. This gives the pieces additional strength and increases their durability.
The most unique thing about stamped rockers is that they don’t operate like roller rockers. That’s because they have a slot that allows the stud to protrude to find the rocker.
However, the centerline of the rocker is constantly changing. Thus limiting the rocker tip’s movement across the face of the valve tip. Moreover, stamped rockers provide a wide tip contact area.
Another unique about these rocker arms is that they’ve got a longer pivot slot. For this reason, you can install a camshaft of up to 0.55 valve lift.
The roller tips are designed to reduce wear and friction in the valve stem and valve train. This reduction in friction increases the horsepower by about 10 to 15 HP.
By buying this set, you’ll get 16 pieces of pivot balls, self-locking nuts, and rocker arms. Each rocker arm has a 1.5 ratio and a 3/8” stud diameter. This allows them to fit most SBC engines, especially 262 to 400 models.
While the pivot balls prevent galling and promote oiling. On the other hand, the locking nuts ensure that the rockers don’t loosen out of adjustment.
- Crafted from high-quality stamped steel
- Includes anti-gall grooved pivot ball and nuts
- Available in a set of 16
- Compatible with most SBC engines

Buyer’s Guide for SBC Roller Rockers
The roller rocker arms serve 2 purposes in an SBC engine. One, they act as fulcrums, where they redirect the lifters’ upward motion.
They also force the pushrods to move downwards to keep the valves open.
Secondly, the rockers’ lift ratio multiplies the amount of valve lift created by the cam lobes.
Although all roller rockers perform these tasks, there are different types out there. So, how do you choosing the best small block chevy roller rockers?
Well, they’re various factors you need to consider before buying a certain unit for your engine. Some of those factors include;
As you may have noticed, roller rockers are made up of different materials. The most commonly used materials are; die-cast aluminum, powdered metal, and stamped steel. These substances have great strength and can withstand various environmental damages.
Besides, these factors play an important role in increasing your unit’s longevity. Longevity is important when dealing with high lift ratios and valve spring pressures.
Still, on material, look for a stiff product. This will improve the rocker arms’ performance. You can also use heavier materials like chrome steel to increase the unit’s stiffness.
Price is another significant factor that can limit your roller rocker options. That’s because roller rocker arms come at different prices.
So, before you buy a certain unit, consider its price, especially if you’re an entry-level racer.
The same case applies if you’re a budget-conscious street customer. However, don’t let price compromise on quality. Instead, settle for a product that’s affordable, but performance efficient.
Rocker Arm ratio
Arm ratio can have a significant impact on your roller rockers’ abilities. For instance, changing the arm ratio can get more lift out of a certain cam lobe profile.
Also, increasing the total valve lift will increase volumetric efficiency.
The same case applies when you increase the speed at which the valves close and open. Simply put, choose a unit with a higher arm ratio instead of rockers with a limited ratio.
Bearings and roller tips
Lastly, look for roller rockers with large bearings and unique roller tips. These components help in friction reduction, leading to better engine performance.
Moreover, this results in lower oil; temperature, high horsepower, and enhanced vehicular response.
Frequently Answer Questions
#1. How do roller rockers increase horsepower?
Rocker arms have bearings and roller tips. These components decrease friction which significantly lowers the oil temperature. Thus resulting in enhanced vehicular response and increased horsepower.
#2. Do you need guide plates when installing roller rockers?
Yes, you’ll need guide plates, especially if your rockers are non-aligning.
#3. What is the difference between 1.6 and 1.5 roller rockers?
1.6 rocker arms raise the valve 1.6X the cam’s lobe lift. Contrarily, 1.5 roller rockers raise the valve 1.5X the cam’s lobe lift. 1.6 rocker arms are ideal for improving the valve lift of a camshaft with low lift.
#4. How do you differentiate non-aligning and self-align rockers?
Non-aligning rockers have a smooth surface at the bottom. On the other hand, self-align units have slight ridges where the bottom meets the valve stem.
#5. How long can you drive with loose/ broken rocker arms?
Faulty rockers will ultimately affect the engine performance. So, avoid driving your car for more than 100 miles if the rockers are bad/ broken.
Installing the best roller rockers for SBC in your engine will benefit your car in various ways. It will increase your engine performance, decrease friction and extend its durability.
You can also use these pieces to increase your engine output.
