Description: BMW 2002 4.10 ratio, E36 Z3 4-clutch spool limited slip differential, 25% - Fully REBUILT + E21 Diff Cover This is a custom built OEM short nose 2002 differential. The formerly open E21 differential with a 3.91 stock ratio was converted to a limited slip using the clutch assembly spool from a 1996-99 E36 Z3 and a 4.10 gear set from an early '80s E30 318i. This spool is highly regarded as being superior to the E21 and E30 spools. The carrier has no preload torque and has a variable ramp angle. The differential was fully disassembled and cleaned. The 4 clutches were removed, cleaned, and media blasted to restore the original friction surface prior to reassembly. The diff case was modified slightly to allow for installation of the limited slip spool, and then the diff was painted, reassembled, and set up with the correct backlash and proper gear contact. New bearings and seals were installed. The stock E21 finned rear cover was cleaned and loosely installed. You will fit your 2002 cover on this unit when you do the installation (you will need to seal it). Also included are custom modified E21 drive flanges to allow for easy installation of 2002 axles and hard anodized billet aluminum spacers and longer hardened bolts so the correct geometry is maintained. Simply bolt this up. All you need to do is seal your rear cover using some RTV or gasket seal compound, add oil, and install it. Fits any 2002 that does not have a long neck diff - basically any made after 1968. This is a rebuilt LSD that comes with a 12 month warranty. I've sold hundreds of used and rebuilt LSDs to happy owners and won't try to pass off a worn out or poorly built diff on anyone. The unit weighs approximately 64 lbs when boxed up. Use the calculator to figure out shipping in the US and worldwide, assuming a 64 lb box can be shipped USPS to your country. For Europe and Australia, figure on about $250-400 for shipping via Fedex. If you are close to San Diego, come pick it up to save shipping $. Thanks for checking this out.
