The design moves both pinion bearings into the case, offering far greater support to other designs where the outer bearing is outside the case.\u003c\/p\u003e \u003cp\u003eTo further reduce flex the pinion support has a very precise fit to the case bore. Then coupled with an oversized tail bearing the pinion gear is held firmly in place. This hold the pinion gear in proper alignment with the ring gear even under the most extreme conditions.\u003c\/p\u003e \u003cp\u003eThis case can utilize 9” and 9 1\/2” ring gears, and can use 10” development gears with the proper pinion support. Strange Ultra Centers have a provision to use an optional load bolt if required.\u003c\/p\u003e \u003cp\u003eThe 3.812” bore Ultra case is designed for a heavy duty lightweight 40 spline steel spool that features a thicker wall on the bearing journal to eliminate the possibility of collapse under the most abusive conditions. It also allows the use of a aluminum 40 spline spool were applications permit.\u003c\/p\u003e \u003cp\u003eThe 3.812” is available in a special lightened version with a ball bearing pinion support commonly used in Pro Stock cars. Ball bearing supports are an option on non-lighten cases as well. For a Funny car requiring a coupler cover, a support with a built-in cover is an option. A special 4.00” bore case is available to suit the Strange L6000 Drop-out Live Axle.\u003c\/p\u003e \u003cp\u003eStrange Ultra Third Member PRF225 with 35 Spline pinion gears is an option for those who need the use of those particular gear ratios.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e \u003cb\u003eThis Center Section May Not Fit Your Housing\u003c\/b\u003e\u003cbr\u003e Please refer to housing clearance diagram\u003c\/p\u003e \u003cp\u003e\u003cb\u003eUltra Case – 3.812″ Bore\u003c\/b\u003e\u003cbr\u003e • 206-T4 heat treated aluminum\u003cbr\u003e • Billet aluminum main caps\u003cbr\u003e • Solid steel adjuster nuts\u003c\/p\u003e \u003cp\u003e\u003cb\u003eTapered Bearing Pinion Support\u003c\/b\u003e – N1950A\u003cbr\u003e • Billet aluminum\u003cbr\u003e • Drilled \u0026amp; tapped for computer pick-up sensors\u003cbr\u003e • (2) 5\/16″-24 and (2) 3\/8″-24\u003cbr\u003e • Clear anodized for corrosion resistance\u003c\/p\u003e \u003cp\u003eHeavy Duty 40 Spline Lightweight Steel Spool – D2002\u003cbr\u003e • Machined from forged steel\u003cbr\u003e • Bearing journal increased to 2.250″\u003cbr\u003e • Provides additional load capacity\u003cbr\u003e • Broached 40 spline with 45° pressure angle\u003c\/p\u003e \u003cp\u003e\u003cb\u003eChoice of 28 Spline Pro Gear\u003c\/b\u003e\u003cbr\u003e For 35 Spline Pro Gear – See PRF225\u003c\/p\u003e \u003cp\u003eChrome Moly Yoke – U1603\u003cbr\u003e • Fits 1350 series u-joint\u003cbr\u003e • Supplied with u-bolts – U1610\u003c\/p\u003e \u003cp\u003e\u003cb\u003eProfessionally Assembled\u003c\/b\u003e\u003cbr\u003e • Timken® Bearings \u0026amp; Races\u003cbr\u003e • ARP ring gear bolts\u003c\/p\u003e \u003cp\u003e\u003cb\u003eOptions\u003c\/b\u003e\u003cbr\u003e Aluminum 40 spline spool – OPRF29\u003cbr\u003e 1350 Billet chrome moly yoke – OPRF08\u003cbr\u003e 1480 Billet chrome moly yoke – OPRF20\u003cbr\u003e HD yoke cap kit – OPRF37\u003cbr\u003e Taper \/ ball pinion support – OPRF26\u003cbr\u003e Lightened case with ball support – OPRF25\u003cbr\u003e Lighten ring gear – D3596\u003cbr\u003e Load bolt – N1910H\u003cbr\u003e (Can’t be used with lightened gear)\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePick-up Collar\u003c\/b\u003e\u003cbr\u003e 1 magnet – U1613\u003cbr\u003e 2 magnet – U1613-2\u003cbr\u003e 4 magnet – U1613-4\u003cbr\u003e 8 magnet – U1613-8\u003c\/p\u003e \u003cp\u003eLightened case sensor bracket – N1952U\u003cbr\u003e  \u003c\/p\u003e","brand":"Strange Engineering","offers":[{"title":"Default Title","offer_id":67678832951596,"sku":"PRF215","price":2475.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/6429\/2652\/files\/PRF205-2_c3df1220-2ece-4800-97b3-08973163beed.jpg?v=1793044604","url":"https:\/\/www.lee-motorsports.com\/products\/strange-ultra-third-member-28-spline-gears-95f7175ca8","provider":"Lee Motorsports","version":"1.0","type":"link"}
