Information
Officially known as the "tensioning plate" the bearing retaining plate in your transaxle is a wear item. Normally you'll start to see a ridge develop on the inside step where the 4 point bearing flange rides. This part is often found damaged or worn out in track driven cars and high power turbos.
Our part is machined from 30,000 psi carbon steel and replaces factory part 996.302.121.9A.
Better and more light weight than the factory machined cast part.
Note: The pass through holes have been deleted to save weight.
Fits 996T, 997T2, 996 GT2, 997 GT2RS, 996 GT3, 997 GT3, 996 GT3 CUP

Information
The factory cast magnesium intermediate plate is known to be problematic. Original ones tend to crack, have loose or out of round bearing bores or may have worn out shift shaft provisions.
Perfect for street, race, higher horsepower and V8 applications-where the additional strength is really needed!
Precision machined from aircraft grade billet aluminum to exacting standards for perfect fit and function
Replaceable silicone bronze shift rail bushings
Lightest weight possible, only 4.25 lbs
Fits all Porsche 901/911 late '69-'71 and 914 '70-'76 magnesium case "die casting" transmissions.
Replaces part 911.301.221.00
Note:
1. If replacing the 4 point bearings it's recommend you use GENUINE PORSCHE only due to dimensional differences we have found between used original, "OEM" new and Genuine Porsche bearings.

Information
We can provide bolt on hydraulic slave cylinder for your Porsche 911 930 4 speed transaxle eliminating all the woes that come with a clutch cable. It can be used for both upright and inverted applications - especially nice for mid engine conversions.
Includes clutch arm, cable clevis, slave cylinder and our billet slave cylinder bracket with bolts. Please specify if your application is using a short bell housing or long bell housing transaxle as the pivot shafts for the release fork are different. We must modify the arm if you have a long bell housing transmission.
