BoostLine is growing fast and we're excited to share some of our newest product launches, why we build rods the way we do, and what racers can expect in the near future.Do the top priorities for your build include extreme horsepower and long-term reliability? BoostLine has made it their mission to create a connecting rod that’s purpose-built for the task. “These were developed to be the last steel rod you’d need to buy for your forced induction or nitrous-fed engine,” says Nickolaus DiBlasi, director of product management for JE Pistons. “They’re built to handle the craziest power you can throw at them.”
Touting the strength to take the all abuse racers can throw at a part is a common refrain in the world of race-spec components, but DiBlasi’s assertion isn’t just lip service.
“We want to cater to those big horsepower guys who want a more reliable program. Engines are making so much power these days – ring technology and tuning is better than it’s ever been, and components are living, so we wanted to make a connecting rod that would complement where we’re at now. That’s why we took a clean slate approach to our design. If you’re going to come out with a product in this space, you just can’t be an ‘also ran’ type of offering. For the guy with a big-block Chevy making three thousand horsepower, there’s some peace of mind to the fact that it will live with these connecting rods. You can’t do that with just any part.”
Strength Under Pressure
The distinctive engineering of BoostLine rods is obvious even at a glance. “The three-pocket design is one of the general guidelines that we follow,” DiBlasi notes. “On the beam of the rod there’s a large milled-out section, and near the outsides toward the big end there’s two milled pockets as well. Those pockets allow us to remove weight from the rod while keeping the part extremely strong – it creates something like a truss in a bridge, which won’t allow it to twist. If it were all solid on one plane, it would actually be more susceptible to twisting than it is with the milling features.”
The design is a result of sophisticated development processes that goes far beyond the typical R&D efforts in this realm. “If you’re developing a product for what we’d consider a ‘medium power’ build, you don’t really need to worry about every aspect of the design – it’s probably overbuilt for the application anyway,” says DiBlasi. “But when you design something and say, ‘this is going to hold 2000 horsepower,’ you need to be damn-sure that you design it to handle that and more, because people are going to throw that much at it. For every application we support, we have an employee who is the expert with that engine, whether that’s a big-block Chevy, a Modular Ford, or a Subaru. And if we don’t have someone in-house, we find a development partner who’s willing to go crazy.”
BoostLine engineers use finite element analysis to determine the most effective balance between strength and weight. “What it enables you to do is apply specific harmonics, loads and frequencies to specific points on a part you’ve designed,” he explains. “In our modeling we can call out materials like the 4340 steel we use with all BoostLine products – materials with characteristics like elasticity and tensile strength that are already well known. From there we can say the big end of this part pivots on a stroke that is, for instance, four and a half inches, it rotates in this direction, we have a piston on the other end, and we apply pressure downward. It means we can basically model a rotating engine and determine how much pressure an engine will apply to a part in a given state, and you’ll see different loads on the rod at different points in its rotation.”
And the end result is a connecting rod that’s vastly stronger than the competition, DiBlasi says. “Just because a brand is recognizable doesn’t mean they’re heavily into engineering. When we first started this development, we bought a bunch of competitors’ rods and put them through this same process to benchmark them, and what we saw were things like ‘high end’ rods that bend 60% more than Boost-lines we developed for the same applications.”
Since BoostLine’s initial launch, the usual suspects like GM’s LS family of small-block V8s, Toyota 2JZ, big-block Chevy, and Subaru EJ20/EJ25 engines have proven to the be the front runners in terms of popularity, along with Ford’s Modular V8s.
“For our introduction of this product line, we wanted to hit the most popular applications and spread out from there,” says DiBlasi. So for big-block Chevy we had one length, for Hondas we had two lengths, for Subaru we had one length, and we really only focused on those. The plan was always to expand beyond that, but because we have a limited amount of time and engineering resources, we went with the heavy hitters first.”
Now BoostLine is ready for Phase Two. “We started considering all the other applications we wanted to do – stuff we couldn’t do the first time around,” he says. “So for instance, we added the next two most popular sizes for big-block Chevy, and for Ford we added four sizes altogether. Our manufacturing processes are really up to speed now, so we can be quicker with development and production this time around. With each iteration, the process gets more efficient.”
The result is an application list that’s nearly double what was initially offered. These new offerings will first start shipping in February, with some of the later additions coming in a few months down the road. By the second quarter of next year, BoostLine will have more than doubled their product lineup.

BoostLine rods for Subaru EJ20 and EJ25 engines takes the power and boost potential of an already potent platform to the next level!
BoostLine connecting rods for highly boosted Subaru EJ20 and EJ25 engines were launched a little over three years ago. These unique, lightweight rods can handle upwards of 1,000-horsepower in 4-cylinder applications and are a substantially more durable alternative to aluminum drag racing rods.
- SB5137-905 Subaru EJ20/EJ25 Turbo 130.5mm - BoostLine
- SB5137-905+ Subaru EJ20/EJ25 Turbo 130.5mm ARP +625 - BoostLine
Note: Block clearancing required above 81mm stroke
“We wanted to develop a rod that was capable of handling the power that a new generation of builders are extracting from their engines with better tuning and fuel, and longer-lasting components,” says Nickolaus DiBlasi, BoostLine’s Director of Product Management. “BoostLine rods are for the majority of people who want to drive their cars on the street and can’t get away with the short life of an aluminum rod. We created a durable, high-performance steel rod that’s different from what everyone else has out there.”
BoostLine’s 4340 chromoly steel rods feature a patented, F1-inspired three-pocket design. Three large voids are milled out of the rod to create a distinctive look that reduces weight and creates a strong, truss-like system to resist bending.
“We haven’t failed one yet,” adds DiBlasi, “and they should be good for many rebuilds. We want this to be the last new rod you have to buy before you go to an aluminum rod and become a full-blown drag racing car.”
The EJ block from DiBlasi’s own Subaru project was used in the development of the first BoostLine rods. To create a perfect fit, BoostLine always begins with a 3D laser-scan of the block. The crankshaft and different stroke iterations are superimposed onto the digital block model to build a design based on a wide envelope. For the relatively big-bore EJ for example, the short standard stroke is 75mm, but with a BoostLine rod, block clearancing is only required for strokes above 81mm.

Not all rods are created equal. Take a deep dive into what makes a BoostLine, a BoostLine as we explore the processes of design, engineering, and manufacturing a boost-ready rod.
When it comes to the rotating assembly, connecting rods can be a bit of an afterthought for builders, with piston design and crank selection often positioned near the forefront of the build strategy. But not all rods are created equal, as BoostLine’s products clearly illustrate. Engineers took a clean sheet approach with these designs, taking the best attributes of many connecting rod styles and merging them into one purpose-built connecting rod that’s capable of handling over 2000 horsepower right out of the box.

Sport compact BoostLine rods are now available with an ARP’s Custom Age 625-Plus rod bolt upgrade. Learn about the differences in rod bolt technology.
Upgrades. They seem to be a pervasive part of 21st Century life. While flying in First Class is certainly nice, it’s a trade off of personal comfort against a somewhat stiffer fare. There are also upgrades for connecting rods but instead of wine with cheese you get that added insurance of a better connecting rod bolt that that offers added peace of mind for that spinning big-block at full song. When you consider the consequences of an expired engine, the tradeoff is well worth the expense.

We reveal the technology behind our brand new 3 pocket BoostLine connecting rod design and how it's able to support 2,000hp+
The lineage of drag race engines – or any race engine for that matter – is written within eyeshot of that shelf of broken parts. This is an ancestry of a learning curve. As power increases, the stress on internal engine components also increases. As piston designs improve to take the abuse of immense cylinder pressures of especially turbocharged race engines, that load is passed right on to the connecting rod.
Keeping Things Straight
It’s clear there was a need for a stronger connecting rod for these high output turbocharged, supercharged and nitrous-assisted engines. Good connecting rods were literally bending under the incredible cylinder pressure loads of 2,000 hp small-block and big-block engines as well as their four cylinder cousins. This has renewed the connecting rod controversy of H-beam versus I-beam.
Both sides have their proponents; we won’t review it all here. We’ll just leave it at the H-beam is typically lighter while the I-beam is generally acknowledged as stronger. Weight plays a big part in the overall consideration with regard to how well the rod can handle what engineers call ‘tensile loading’. Smart engine builders know that while boosted engines can bend a connecting rod with compressive loads, engine speed also plays a big role.
