This kit lets you make that change. It converts a 94-97 GS-R or Type R differential from the tapered setup to the ball bearing design used from 98 on, which is what most builders want when the case is already apart.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Ball Bearings Over Tapered\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding, because it explains why this conversion exists at all.\u003c\/p\u003e\n\n\u003cp\u003eTapered bearings handle thrust load well, but they require preload to be set correctly and they generate more friction than a ball bearing does. That preload also changes as things wear and as temperature moves, which means the setting you dialed in cold isn't necessarily what you have at operating temperature.\u003c\/p\u003e\n\n\u003cp\u003eBall bearings run with less friction and are considerably less sensitive to preload variation. Honda's own switch to the ball bearing design on the 98-01 transmissions tells you which they preferred once they had the choice.\u003c\/p\u003e\n\n\u003cp\u003eFor anyone building a transmission, that means one fewer setup variable to get exactly right and a differential that's more forgiving over time.\u003c\/p\u003e\n\n\u003ch4\u003eCheck Your Differential First\u003c\/h4\u003e\n\n\u003cp\u003eTwo things to confirm before ordering, and they're both quick.\u003c\/p\u003e\n\n\u003cp\u003eThis kit is for the \u003cstrong\u003e10 bolt differential with tapered bearings\u003c\/strong\u003e, which is what the 94-97 GS-R and Type R transmissions came with.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIt will not fit the 14 bolt viscous LSD.\u003c\/strong\u003e If that's what's in your transmission, this isn't the right kit.

But cases vary, bearings vary, and assuming the included shim is correct because it came in the box is a bold assumption on a differential you're about to seal up.\u003c\/p\u003e\n\n\u003cp\u003eMeasure your actual clearance during assembly. If the number calls for a different thickness, use one. Getting differential preload wrong means either a bearing that's running loaded and wearing early, or one with play it shouldn't have, and either way you're splitting the case again to fix it.\u003c\/p\u003e\n\n\u003cp\u003eWe stock \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/honda-d-b-k-l-r-series-differential-thrust-shim?_pos=2\u0026amp;_sid=960eaf45f\u0026amp;_ss=r\" target=\"_blank\" rel=\"noopener noreferrer\"\u003edifferential thrust shims for Honda B, D, K, L, and R series transmissions\u003c\/a\u003e in a range of thicknesses, so if your measurement calls for something other than 1.45mm you can get exactly what you need rather than making do.
