• Designed to handle 600 HP at the wheels.

"Level 5" Axle/Hub Upgrade:

• Includes Outer CV Joints, Outer Hubs, and Bar Upgrade.
• The Outer CV Joint is completely redesigned and much larger than the Level 2 CV Joints.  It is made from 4340 steel, with a unique Carbo Ausee Tempering that gives it a very hard shell.
• The Outer Hubs are custom, and redesigned to accept the larger CV Joints.  
• The Center Bar is manufactured from 300M steel.
• Designed to handle 900 HP at the wheels.
• This system includes both Axle Bars with the custom outer CV Joints installed.  All you have to do is install your factory inner CV Joints, just like the Level 2's.  A Ball & Cage design inner CV Joint is also available.
• Kit also includes 3" ARP Wheel Studs, Inner Boots, Clamps, and Grease.
• 1 Year Warranty.

2005-2008 Mustang 1-Piece Driveshaft:

• 1-Piece driveshaft design, instead of factory 2-Piece design.
• Weighs 23 lbs., factory 2-piece weighs 46 lbs.
• Has normal joints at both ends.
• Comes complete with a 7075-T6 aluminum plate for the rear to convert it over from the current CV design.
• 600 HP Driveshaft:Features solid joints that are not only stronger, but will also keep the underside of the car clean.  The factory driveshaft has a grease fitting joint, which is made to expel grease to keep it self lubricated.
• 1000 HP Driveshaft:Features a larger tube than the 600 HP version and 1350 joints.

Notes:

• (1):For 1999 Cobra's, if you are not purchasing an Axle Upgrade that includes Inner Joints, you must upgrade from a 28-Spline to a 31-Spline differential.  You will also need inner CV Joints from a 2003-2004 Cobra.
• (2):For 2001 Cobra's, if you are not purchasing an Axle Upgrade that includes Inner Joints, you may need inner CV Joints from a 2003-2004 Cobra.  The splines between the inner CV Joint and the Axle Bars need to be 31-Spline.  Most 2001 Cobra's have 31-Splines, but some came with 28-Splines.  The only way to tell for sure is to remove a half-shaft, remove the inner CV Joint, and count the splines.
• (3):Open ended lug nuts are recommended due to the 3" ARP wheels studs that are included.  The only other option is to cut the ARP wheel studs down to the length of the factory wheel studs.  Factory wheel studs can not be used, as the wheel stud holes in the outer hub are much larger in diameter, to accept the knurled, "press-in" section of the ARP wheel studs.  We also recommend purchasing a pair of Ford outer hub bearings.  If you do not, you will have to "press" your factory outer hub bearings off of your factory hubs, which typically results in damaging or ruining the bearings.
