Precision-engineered from high-tensile 4340 chromoly steel, these two-piece shafts are built to handle up to 300 bhp while absorbing drivetrain shock to protect your differential and crown wheel and pinion (CWP).\u003c\/p\u003e\n\u003cp\u003eDesigned with an extra-long inner spline section, they fit standard-width Escort English axles out of the box and can be easily trimmed to suit narrowed casings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow the Group 1 Setup Works\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Piece Construction:\u003c\/strong\u003e Unlike factory single-piece forged shafts, the Group 1 design separates the drive shaft from the outer wheel flange.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollarless Bearing Retention:\u003c\/strong\u003e Traditional English half shafts rely on a pressed-on metal collar to hold the wheel bearing in place. The Group 1 setup removes this collar completely; instead, the separate bolt-on outer flange clamps directly against the inner bearing race to lock it securely onto the shaft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Casing Compatibility:\u003c\/strong\u003e The assembly uses classic English axle wheel bearing dimensions and secures into the casing using the included retaining plates and spacers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTrimming Guide for Narrowed Axles\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBecause each shaft features an extended 100 mm inner spline section, you can cut the shafts down to fit custom narrowed axle casings:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExample (46\" Narrowed Casing): A standard Escort English axle measures roughly 48.5\" flange-to-flange. Narrowing the casing to 46\" removes 2.5\" (63.5 mm) overall, or 1.25\" (31.75 mm) per side.\u003c\/li\u003e\n\u003cli\u003eSpline Engagement: Trimming 32 mm from the end of each shaft brings the overall length to ~693 mm and leaves 68 mm (2.68\") of usable spline - more than double the 28–32 mm required for full engagement inside an 18-spline LSD side gear.\u003c\/li\u003e\n\u003cli\u003eMinimum Width Limit: You can safely narrow a Ford English axle casing down to approximately 43\"–43.5\" (1,092–1,105 mm) flange-to-flange while maintaining full spline engagement.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Blackline","offers":[{"title":"Default Title","offer_id":57740824576375,"sku":"MLR.BSX","price":484.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/0703\/4172\/files\/GROUP_1_HALF_SHAFT_KIT_webp.webp?v=1794493449","url":"https:\/\/mattlewisracing.co.uk\/products\/blackline-ford-english-axle-18t-heavy-duty-group-1-half-shaft-kit","provider":"Matt Lewis Racing","version":"1.0","type":"link"}
