Product Features:

 

Currie Centurion Housing

Classic notchback looks in a new, high-strength, housing that features 3-inch diameter axle tubes and CNC machined face flange for a flat, leak-free seal - all joined together with strong, attractive welds

Drain Plug

This standard feature makes routine maintenance so much easier - no more removing the brakes, axles, and the third member and scooping out dirty gear oil for a simple oil change

Gear Case

A choice of nodular iron or aluminum gear case with Daytona big bearing pinion support is the perfect foundation for a performance restomod build - no used or reconditioned parts here!

Master Bearing Kit

High-quality Timken or Koyo bearings and performance seals are used throughout to provide a long, trouble-free service life

Gear Ratio

Select from a wide variety of ratios, Currie uses only the highest quality Motive Gear Performance® series (Orange box) ring and pinion sets in our 9-inch crate rear ends

Differential

Select the differential type that meets your traction needs, including helical gear limited-slip, automatic locking differential, or steel spool

OE-Style Spring Pads

Heavy-duty OE-style spring pads installed in the factory locations for bolt-in compatibility with the stock mono-leaf (top), multi-leaf (bottom) style rear springs

Ridetech 4-Link Brackets

Heavy-duty laser cut 4-link and sway bar brackets are installed on the housing for a direct bolt-in fit with your Ridetech suspension

Detroit Speed Quadralink Brackets

Heavy-duty laser cut 4-link and sway bar brackets are installed on the housing for a direct bolt-in fit with your Detroit Speed rear suspension

Billet Housing Ends

Currie billet late model Ford Torino large bearing housing ends are CNC machined for accuracy and feature provisions for internal or external axle oil seals

Alloy Axles

Currie Performance 31-spline or 35-spline 1541 alloy axles with tapered axle bearings feature vehicle correct bolt pattern and wheel studs

Brake Package

Select from a range of brake options from classic 11-inch drums to 14-inch Baer and Wilwood disk brakes that are capable of meeting any performance requirement

Powder Coat

Optional powder coat finish adds long-lasting protection against rust and corrosion to keep your rear end looking its best

Fully Assembled

Complete rear ends and third members are fully assembled in-house by our skilled professionals and shipped ready to install

 

 

NOTES:

Lubrication Requirements - 9-inch rear-ends use a high-offset hypoid gear design requiring severe duty gear oil with API GL-6 rating. Oil not meeting the GL-6 rating will damage the gears and bearings and void the Currie Warranty. See Currie Racing Gear Oil P/N CE-9013 or CE-9015

Brake Lines - Rear ends equipped with a brake package will include flex lines installed (rubber for Explore brakes,  braided stainless for Wilwood and Bear brakes). Hard Brake lines are not included

70-81 Ridtech Rear End - The brackets on this rear end are compatible with Ridetech's 2023 and newer 4-link suspension system, they do not fit the 2022 and earlier 4-link suspension design.

Wheel Studs - Leaf spring housing and axle kits include 7/16 wheel studs, Detroit Speed and Ridetech housing, and axle kits include 1/2 wheel studs.

Aftermarket Brakes - Currie crate rear ends conform to the ABCS (Aftermarket Brake Configuration Standard). This allows brake kits that use this standard to be easily changed or upgraded without modifying the housing or axles. ABCS brakes use a 2.5-inch brake space with late-model big-bearing Ford housing ends and a 2.80 center hole in the drum or rotor
