Product Description
We are proud to finally announce the release of our HalferLand Performance J35 - 4340 Chromoly Forged H-Beam Connecting Rods. Yet another piece to the puzzle in offering the "DIY/Garage Built" customer the ability to build a High Hp J-Series motor from home!! We worked very closely with our manufacturing partner to bring these rods to the J-Series community.... and at an affordable price! From the ground up we blueprinted and spec'ed our rods to reflect our needs, taking advantage of all of the industry proven manufacturing techniques that so many other companies cheap out on to save a buck (Chamfered Small and Big Bore ends, Bronze Bushings, Double shot peened, Big Bore End Foot Bridge Support, H beam style which requires more machining cost but hands down is the strongest style rods available, etc etc) and the needs of our High HP Daily Driver Customers, without breaking the bank. We started with a blank H-Beam canvas, spec'ed the rod to our needs for the J35 engine setup, added a few minor touches such as our Big Bore End Foot Bridge Support and when all was said and done the strength software used to rate our J35 H-Beam Rods raised the HP rating to what you see now (Warrantied 1yr at 1000hp, but stress testing showed in excess of 1300hp capabilities)! We didn't just rely on computer modeling, these exact rods have ran in our Shop R&D 06' Accord Turbo setup for over 30,000 miles of daily and racing abuse (and climbing 2022 update), making 600+HP the entire time. We also partnered with a few of our racing sponsorships who have gone well above the 800-1000whp mark...not a single issue since we released these, NOT ONE!
Whether you're forging the bottom end of your J35 or stroking your J30/J32 Motor
(J30 with J35 Rods/J35 Crank = J33........J32 with J35 Rods/J35 Crank = J35 ;) rest assured our HalferLand 1300hp J35 Forged H-Beam Rods will get the job done...All the while also being backed by our HalferLand Performance (1yr) Guarantee.
Along with the Rods as a full set, they will also include a complete set of 1500hp+ 3/8th Bolt/Hardware at no extra charge. This way you are sure both the rods & bolts are up to the task you're asking from it.
~ Common Questions ~
Why did you go H-Beam, aren't I beam stronger?
No! H-Beam hands down have proven to be the strongest design possible for connecting rods in real world testing and computer generated models. We targeted our intended customer group, the Honda Jseries enthusiast, revving up to 8k rpm, not 10k rpm as say a K series where I-Beam may be a better, yet weaker fit. The J-Series engine simply doesn't rev as a K-Series engine and even with a huge camshaft to try to overcome the 8k rpm power band, simply put these engines won't make much power beyond that mark...so we built the strongest Forged Rods SPECIFICALLY tailored to the J-Series engine!
Here's a short piece from the experts at EngineLabs explaining this. To keep this short, we did not want to sacrifice any strength just to reduce a little weight, we wanted and do offer the most tested, backed and strongest J-Series Rod on the market (and affordable!
H-beam rods were born out of necessity during WWII when rod failures in fighter planes occurred as allied fighter pilots used nitrous oxide to boost break away speeds during dog fights.
There is constant debate about which is better, the I-beam or the H-beam rod. H-beam rods are usually more rigid and may better distribute the loads and compressive forces placed on them. They may be ideal for lower speed engines running power adders. There are trade offs for this improved strength. H-beam rods can be heavier, sometimes 100 grams more than comparable I-beam, and require greater clearance — something to consider with stroker cranks and large-bore cams. They also require more machining during the manufacturing process, adding to their expense.
I-beam rods can save weight and give additional clearance with only a small sacrifice in strength. This strength loss is minimal in high-end I-beam rods if the materials used are the same as a comparable H-beam. Additional material can be added to the design to further strengthen an I-beam but in some cases that may push overall weight closer to that of a comparable H-beam. I-beams are generally preferred for higher rpm applications.
I Heard Billet is Better and stronger then forged!?
Again, No. We will once again allow the experts at EngineLabs explain this
