12doplumbing Posted November 20, 2014 Share Posted November 20, 2014 So, does anyone know why this "bearing" style pilot is shorter than the stock "spacer" style that came with my clutch kit? Also, wondering what performance value this "bearing" style will/would offer. Don't want to install this "just because". Quote Link to comment Share on other sites More sharing options...
johnc Posted November 20, 2014 Share Posted November 20, 2014 The roller bearing style offers no performance advantage unless you're consistently shifting above 7,000 rpm. Even then, its probably not significant. Quote Link to comment Share on other sites More sharing options...

Tony D Posted December 1, 2014 Share Posted December 1, 2014 VW's with engines that redlined at 5,000 had roller bearing input shaft supports. It's Germany. "Zis ist der vay vee do it!" If you get into specific bearing loads for rollers and journal bearings and their constituent componentry, it explains different lengths. But as JC said the bushing works just fine. And if a bushing fails, it's far easier to clean up,than if a roller pilot bearing seized and welds your crank to your tranny input shaft...

skirkland1980 Posted December 3, 2014 Share Posted December 3, 2014 The beating doesn't turn while the clutch is engaged anyway so yeah not much better than a bushing. Plus its more likely to fail. Quote Link to comment Share on other sites More sharing options...
