Whitehead Performance Home of the Z Car Differentials
When it comes to restoring, modifying or upgrading your Nissan or Datsun Z Car look no further as we’ve got you covered. We supply happy customers all over the world with everything they need for their drivetrain upgrades. Here at Whitehead Performance we pride ourselves in providing the best upgrade components for your Z car and we are by far the best one-stop Diff/Drivetrain Upgrade Shop. We scour the world for the most popular long-nose R200 LSD and R180 diffs. After we locate the diffs we bring them all together at our shop and personally inspect each one. Once the diffs have been approved they are listed for sale on our webstore.
Whitehead Performance Latest Diff Shipment
With our recent shipment, we are now currently stocking long-nose R200’s and R180’s in the following ratios:
Side bearings have been checked for wear and proper clearance, ring and pinion teeth checked for excessive wear and damage, backlash has been measured and is within factory specs, clutch unit has been tested for break-away torque and general operation.
While we strive to ensure each diff is in good working order, being a used part, we cannot guarantee these R200 diffs are 100% trouble free.
Our experience installing these diffs in customer cars in our shop has been overwhelmingly positive. The only advice is make sure to change the seals first.
At a minimum, we highly recommend our Diff Reseal Service. For $100 parts and labor inclusive, the pinion seal and side seals will be replaced with OEM seals and the rear cover gasket replaced with an OEM part.
A CLSD Refresh Service is also available to restore breakaway torque to the upper range of factory spec or to increase breakaway torque to competition specs.
We do offer a Diff Rebuild Service using all OEM parts for those needing extra assurance and reliability. Any refurbished diff will be fully guaranteed.
We have the capacity to build a diff in any ratio with a used ClSD unit, new OS Giken clutch-type LSD unit, or Quaife gear-type LSD unit.
