Driveshaft Shop's X4 line is built from 300M with their best heat treat processes, rated to handle 700 to 1000 wheel horsepower depending on application, and it's a direct bolt-in. On an EF running a B-series cable transmission and real power, this is the tier that stops axles being the weak link.\u003c\/p\u003e\n\n\u003ch4\u003eCable B-Series, But Not Y1 Or S1\u003c\/h4\u003e\n\n\u003cp\u003eRead this before ordering, because the exclusion matters.\u003c\/p\u003e\n\n\u003cp\u003eThese fit B-series \u003cstrong\u003ecable\u003c\/strong\u003e transmissions with the \u003cstrong\u003eY2, A1, and J1\u003c\/strong\u003e codes.\u003c\/p\u003e\n\n\u003cp\u003eThey do \u003cstrong\u003enot\u003c\/strong\u003e fit the \u003cstrong\u003eY1 or S1\u003c\/strong\u003e. Those transmissions take different axles, and they aren't interchangeable.\u003c\/p\u003e\n\n\u003cp\u003eIf you're unsure which you've got, check your intermediate bar hanger bracket. A Y1 carries \u003cstrong\u003eSH3\u003c\/strong\u003e on the casting. If yours reads SH3, this isn't your set.\u003c\/p\u003e\n\n\u003ch4\u003e300M Is Why It Holds\u003c\/h4\u003e\n\n\u003cp\u003eThe material is the reason for the rating, and it's a genuinely different tier from what ordinary axles use.\u003c\/p\u003e\n\n\u003cp\u003e300M is a high-strength alloy used where failure isn't an acceptable outcome. Combined with Driveshaft Shop's heat treat processes, it's what lets these handle the torque and shock loading that destroys lesser axles on a hard launch.\u003c\/p\u003e\n\n\u003cp\u003eAxles typically fail in torsion rather than bending, so material strength through the bar is what determines whether one survives a sticky tire and a built engine. That's where the 700 to 1000 wheel horsepower range comes from.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt For Cars That Do Both\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding the positioning, because it's specific.\u003c\/p\u003e\n\n\u003cp\u003eDriveshaft Shop engineered the X4 line for fast street cars that visit the track for drag, road course, and autocross duty. That's a demanding category, since the axle sees daily driving loads, launch shock, and sustained cornering load all in the same week.\u003c\/p\u003e\n\n\u003cp\u003eOn an EF making real power, that's usually the profile. These cars are light, they're quick when built, and they mostly still get driven.\u003c\/p\u003e\n\n\u003ch4\u003eDirect Bolt-In\u003c\/h4\u003e\n\n\u003cp\u003eNo hub change, no modification, no adapting anything. These go in where your existing axles came out, which keeps the job straightforward and keeps the cost to axles rather than an entire package.\u003c\/p\u003e\n\n\u003ch4\u003eNon-Refundable After Installation\u003c\/h4\u003e\n\n\u003cp\u003eWorth stating clearly. Once installed these can't be returned, which is standard for driveline components at this level.\u003c\/p\u003e\n\n\u003cp\u003eThat's another reason to check your transmission code first. Confirming a casting mark costs you two minutes. Ordering wrong costs considerably more.\u003c\/p\u003e\n\n\u003ch4\u003eCheck Your Range Of Motion After Install\u003c\/h4\u003e\n\n\u003cp\u003eOnce fitted, cycle the suspension through full travel and turn to full lock both directions. You're checking that the inner joint isn't bottoming out at compression or over-extending at droop, and that everything clears through the steering range.\u003c\/p\u003e\n\n\u003cp\u003eOn a lowered or swapped EF this matters more than it would on stock height, since the axle is working through angles Honda didn't plan for.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1988-1991 Honda Civic\u003cbr\u003e1988-1991 Honda CRX\u003c\/p\u003e\n\n\u003cp\u003eB-series cable transmissions: Y2, A1, and J1. \u003cstrong\u003eDoes not fit Y1 or S1 cable transmissions.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003ePart number 510499 \/ 510014.

Real power on the street, track days on the weekend, and a set that won't be the thing that ends your day.
