Remember when a 1,500 horsepower street motor was the stuff of fairy dust and unicorns?

BoostLine remembers. And more importantly, BoostLine knows that (GASP!) the 2,000 hp number is getting less and less mythical too.

That’s why the BoostLine folks have gone back to their proverbial drawing boards to update and enhance their already stout connecting rods to handle those ever-increasing power levels.

We spoke with Bryce Mulvey, a product manager with BoostLine to get the lowdown on this new connecting rod design.

“The power levels just aren’t what they were four or five years ago when we originally designed these,” he laughs. “We redesigned the pin end of the rod—the blade thickness, the strap thickness—and put more meat on the big end.”

The end result? Bryce says these rods are 40 percent stronger than the outgoing BoostLine options.

“The biggest thing is just the power levels,” he continues. “As power levels go up, the wrist pins get thicker and the pistons get heavier, and you apply way more stress on the rod.”

Suffice it to say, this new BoostLine connecting rod design is the solution.

Then Bryce picks one up and shows us the neatest part…

“We took our traditional three-pocket design,” Bryce explains, pointing to the triangular recesses at the bottom of the rod. “And we machined it down, so that the rod has an identical weight to the old design.”

In other words, you’re getting a beefier, stronger rod that’s the same weight as the old BoostLine rods—which means you won’t have to re-balance your engine when you swap these suckers in.

“Nobody thought five years ago that somebody would want to build a 2,500 horsepower LS motor to drive on the street,” Bryce chuckles. “We had a strong rod already, but this is really just the next evolution of how we make it perform even better as we go down the road.”

He says that the LS and Gen. III Hemi rods were the first to get this new design, and they’re available now. Next, the team is hard at work updating the Big Block Chevy rods for early 2025. After that, the focus is on the Ford Mod Motor rods, before moving on to the rest of the connecting rods in BoostLine’s portfolio.
