smoorenc Posted January 7, 2011 Share Posted January 7, 2011 I see 2 different Tilton master clutch cylinders. 75 series 75-875u kit that has a Close tolerance cut-off ports: shortens "dead" stroke of pedal for quicker activation and improved feel, in black, that is out of stock. OR the 74 series 74-874u. Can anyone with experience tell me which one. All's I see when reading is people use the 7/8" Tilton, not which series. I REALLY don't want to blow out my slave in the T56. Thanks! Scott Quote Link to comment Share on other sites More sharing options...
h4nsm0l3m4n Posted January 7, 2011 Share Posted January 7, 2011 Looking back in my notes I believe the MC I used was #75-875U. I am using it with the original LS1 clutch and it seems to work fine. I'm no expert but both those parts have the same bore and stroke so the amount of fluid displaced in the end should be the same. I think you could use either one...

I recognize the 75-875u PN as well. Quote Link to comment Share on other sites More sharing options...
smoorenc Posted January 11, 2011 Author Share Posted January 11, 2011 (edited) Thanks guys, I ordered the Tilton #75-875U. Mark also is using this one. Speedway has the stainless AN -3 to GM quick connect lines that connect to the tranny Edited January 11, 2011 by smoorenc Quote Link to comment Share on other sites More sharing options...
SUNNY Z Posted January 11, 2011 Share Posted January 11, 2011 Thanks guys, I ordered the Tilton #75-875U. Mark also is using this one. Speedway has the stainless AN -3 to GM quick connect lines that connect to the tranny :blink: Holy CRAP thats expensive. I guess though, @ $6/ft, and then $15 for each fitting. This hobby sucks! lol Quote Link to comment Share on other sites More sharing options...
cheesepocket Posted January 12, 2011 Share Posted January 12, 2011 875U here as well. Do yourself a favor and pre-bleed your slave cylinder and buy a remote bleed hose while you're in there. I had to pressure- and vacuum-bleed several pints through to get full clutch disengagement, and it would have been much more painful without a remote bleeder. Don't have the maker handy, found it on LS1tech site. I bought Earl's fittings and Teflon lined hose (Speedflex I think) which allowed me to make the right length hose and not have to coil it up. Good luck! Quote Link to comment Share on other sites More sharing options...
smoorenc Posted February 21, 2011 Author Share Posted February 21, 2011 I installed the Tilton 7/8" 75 series with the speedway quick connect and it works. I used a small amount (6 inches) of Russel teflon brake line and some fittings to pull it all together. Thanks everyone. Quote Link to comment Share on other sites More sharing options...
EvilC Posted March 31, 2011 Share Posted March 31, 2011 I am at the point where I am ordering parts again for the car. I already have this clutch: http://www.hrpworld.com/index.cfm?tpc=Tilton_-_74_Series_Master_Cylinder_Kits&form_prod_id=889&action=product Also ordering: http://www.summitracing.com/parts/RAM-78510/ As for as the clutch line itself, I would like to keep the quick release but the fitting from Speedway has the stainless AN -4 to GM quick connect lines that from memory wouldn't work on the clutch master? I forgot what size adapters come with the clutch master kit. You guys who made your own line, used a AN -3 fitting correct off of the master to what on the throw out bearing? Thanks. I feel like a newbie again! I welded up a fitting the first time around and just trying it different way this time. Quote Link to comment Share on other sites More sharing options...
