FITMENT TAG CORRUPTION (brand-wide template pattern): fitmentTags include Integra 1986-1989 (D16A1, no B-series), Integra 1990-1993 (B18A1, not B18C), Integra Type S DE5 2024 and Integra A-Spec 2023-2024 (K20C1\/1.5T, not even B-series). Same DE5\/2023+ corruption seen across the brand. Only the Integra 1994-2001 tag is valid.\n2. FITMENTSLIST OVERREACH: structured rows list ALL 1994-2001 Integras with no trim scoping. B18C1 was GS-R only; B18C5 was Type R only (1997, 1998, 2000, 2001, no 1999 USDM ITR). Base RS\/LS\/GS\/SE cars ran the non-VTEC B18B1 and take a DIFFERENT rod (137mm vs 138mm). Recommend scoping fitment to GS-R and Type R trims.\n3. CATEGORY: null. Recommend Engine \/ Connecting Rods - 4Cyl to match the K24 rod page. productType also null. Status: Draft. schemaDescription: null. Zero sales and zero GSC are explained by Draft status; publish.\n4. SPEC CONFLICT: SpeedFactory's own page lists rod weight at 530g; Titan, IPG, and Jason Waters Tuning list 500g. Using 530g per manufacturer. Worth confirming with SpeedFactory.\n5. SHIPPING DIMS: 6 x 6 x 12 at 6 lbs, same pattern as the K24 SKU. Verify boxed weight.\n6. COST: 316.78 present in export and live PIM. No zero-cost bug.\n7. CROSS-SELL \/ CONFUSION RISK: HR already has a live page for the SpeedFactory B18A\/B\/B20 rod (137mm, 547g). These two get cross-shopped on LS\/VTEC builds and buying the wrong one is a guaranteed return. Body copy addresses it; consider linking the two pages both directions.\n8. COMPETITOR INSIGHT: Skunk2 Alpha Series B18C rods (306-05-1120) are the same positioning (4340 H-beam, 900 hp, similar price tier) and HR carries Skunk2. Comparison shoppers will look at both.\n--\u003e\n\u003ch3\u003eSpeedFactory B18C H-Beam Connecting Rods\u003c\/h3\u003e\n\u003cp\u003eStock B18C rods are happy at factory power and factory redline, and that's about it. Once you bolt a turbo to your GS-R or start chasing big compression and RPM in a DC2 Type R build, the rods are what let go first. The SpeedFactory Racing B18C H-beam connecting rods are the affordable fix: forged 4340 chromoly, rated for over 225 hp per cylinder (900+ hp total), and lighter than many competing H-beam rods.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eThis is a set of four 138mm center-to-center rods for the B18C family, meaning the B18C1 in the 1994-2001 Integra GS-R and the B18C5 in the Integra Type R, plus JDM B18C variants running the same bottom end architecture. Each rod is forged from SAE 4340 chromoly, 100% CNC machined, multi-stage heat treated, magnafluxed to catch internal flaws, and shot-peened to relieve stress. Precision alignment dowels locate the rod caps, keep the big end bore round, and eliminate cap walk under load, which is a real failure mode on cheaper rods.\u003c\/p\u003e\n\u003cp\u003eThe pin end runs a bronze alloy bushing with dual offset oiling holes for floating wrist pins, and SpeedFactory includes 3\/8 inch ARP2000 rod bolts rated at 220,000 psi, ARP assembly lube, and instructions in the box. Each set is weight matched to within 1 gram, so your machine shop starts from a balanced baseline. For a boosted B18C making 500 to 700 whp, or an all-motor build spinning past stock redline, this is the insurance the factory rods can't offer.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHonda\/Acura B18C (B18C1, B18C5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eForged SAE 4340 chromoly steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCenter to Center Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e138mm (5.433 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e530 grams per rod (per manufacturer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePin End Bore\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21.02mm (0.828 in), bronze bushed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePin End Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21mm (0.827 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBig End Bore\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e48mm (1.890 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBig End Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21.79mm (0.858 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRod Bolts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3\/8 in ARP2000, 220,000 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e900+ hp (per manufacturer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBalance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSet matched to +\/- 1 gram\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 rods, ARP2000 bolts, ARP lube, instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSF-02-105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eThese fit B18C engines only.

JDM B18C engines (SiR-G, Type R) share the same rod dimensions. The pin end fits most aftermarket pistons without additional machining, and these rods do not work with OEM style pistons at all.\u003c\/p\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhat to Know Before You Buy\u003c\/h3\u003e\n\u003cp\u003eBuy by your block, not your head. This is the number one mistake with B-series rods. If you're building an LS\/VTEC or B20\/VTEC, your bottom end is a B18A, B18B, or B20, and those blocks take a 137mm rod, not this 138mm B18C rod. SpeedFactory makes that version too and we carry it, so grab the B18A\/B\/B20 rod set for those builds. This page is for actual B18C blocks only.\u003c\/p\u003e\n\u003cp\u003ePlan pistons and rods together. The bushed pin end wants aftermarket forged pistons, and if you're thinking about reusing the stock slugs, these are not your rods. Most B18C builds pair these with forged pistons, King or ACL bearings, and ARP head studs, and that combination holds serious boost on a proper tune.\u003c\/p\u003e\n\u003cp\u003eThe included ARP2000 bolts handle the overwhelming majority of builds, including boosted street cars and all-motor setups revving to the mid 8000s. If you're building a 9,000+ rpm screamer, talk to your engine builder about stepping up the rod bolt spec before final assembly. Either way, torque them with the included ARP lube and a stretch gauge, and have your machine shop verify bearing clearances even though each set comes balanced to within a gram.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003eThese fit B18C engines only.
