Nissan parts are now becoming scarce in the junkyards, builders are swapping to 6 speed Transmission's and aiming for higher horsepower numbers than ever before. This sent us back to the drawing board to see how we could meet the demands of our customers! After another year of design time we are proud to introduce our Ford 8.8 Rear End Conversion for the Z Car! 

Our 8.8 conversion kit comes with a ton of extra value! In addition to the mounting components, this kit includes our custom aluminum differential cover, brand new outer 5-lug hubs in your choice of stud length, and brand new completely assembled CV’s with custom machined and heat-treated axles. The 8.8 kit makes sourcing gear ratios and affordable limited slip differentials so much easier.

Which diff does this kit fit? The 8.8 Differential our kit uses is from 07-10 Ford Explorer (non sport-trac) or Mercury Mountaineer. Our 8.8 differential cover must be used with our kit as it has the correct spacing and holes for mounting to our mustache bar. The 8.8 REC also requires the use of our Power Cradle for the differential mounting on the pinion side.

Once the diff is mounted, our drop mount and dogbone, 8.8 Rear Coilovers, 8.8 Backing Plate/Rear Knuckle, 8.8hubs, and 8.8 axles are the last things needed to piece our 8.8 REC together. (8.8 REC kit is available ONLY IN 5-LUG at this time, 4-lug options are being explored)

If you have our existing R200/R230 Rear End Conversion you may upgrade by purchasing select components. Your existing coilovers, backing plates, brake kit, drop mount and dogbone and Evolved mustache bar can all be re-used.  The older steel style front diff mount for R200/R230 is not compatible with the 8.8 differential so you will need to get the Power Cradle. You'll then need our older style 8.8 Hub adapters to use our 8.8 hubs, then our 8.8 diff cover and 8.8 axles to finish the R200/R230 REC to 8.8 REC. 

You may also use our T3 Rear BBK or Micro Rear BBK (with or without E-brake).

Required modifications and notes;

Your chassis must be notched right above the diff cover just like if you were installing a R230, the 8.8 is a large diff. We include a weld in reenforcement plate that also acts as the template.

Rear differential cover has fill plug in a higher location that the vent is attached to. Differential oil capacity is 1.8 Qts. DO NOT OVERFILL.
