This is a quality OEM Diff Flange, not a cheap copy one. This is a 4 bolt diff flange conversion kit to replace the rubber drive coupling (doughnut) on the rear of Discovery 300Tdi when you fit a wide angle rear propshaft. It is required when you fit a suspension lift on late Discovery300 as the rubber drive coupling doesn’t last long. A new propshaft will also be required as wide angle propshafts have a 4 bolt flange instead of the 3 bolt as standard. This 4 bolt flange kit will also fit front diffs. You can also use one of these 4 bolt flange kits to fit an earlier Discovery & RRc 4 bolt flange propshaft on later Discovery & RRc. This flange comes complete with a built in 12.5mm spacer as many others don’t have the spacer, if you do fit one without the spacer it will cause the diff to seize up. It also has a recessed metal mud shield to help stop mud and debris getting to the oil seal, (please note the built in spacer is not a propshaft spacer, it is a spacer that is part of the internal part of the flange, the piece that goes into the diff itself where the oil seal runs on) We do not recommend fitting propshaft spacers as it stops the propshaft fully closing, it can break the transfer box off the gearbox if the propshaft cant fully close. Torque setting of centre nut/bolt 85 lb ft / 115 Nm This kit consists of 1 x 4 Bolt Flange with built in inner spacer, 1 x Recessed mud shield ready pressed onto the flange, 1 x Oil Seal, 4 x Propshaft bolts & nuts, 1 x Pinion Nut, 1 x Pinion Bolt and 1 x Split Pin.
