Upgraded CV joint axle and hub for use with a stock differential

Fits Triumph TR4A, TR250 and TR6

Sold as a pair



CV joint axles are an excellent modern upgrade for your TR6.  CV joints are stronger, more efficient and smoother operating than the original universal joints.  The benefits include less chance of failure, more power delivery to the wheels and better handling.

This pair of axles are the correct length to fit in a Triumph TR4A, TR250 or TR6 with an original differential installed.  The assembly includes two Good Parts upgraded rear hubs (SKU 112) with your choice of wheel stud length.  The kit includes adapters to bolt the axles to the original differential and mounting hardware for the axles and hubs.

NOTE:  Some grinding may be required for proper installation.  For more information click here for installation instructions.

Available Wheel Stud Lengths:

7/8″ = Wire wheels

1-3/16″ = Factory steel wheels and most aftermarket alloy wheels

1-3/8″ = Alloy wheels with thicker center flange (may require measuring to ensure proper lug nut thread depth)

1-9/16″ or 1-3/4″ = Wheels + wheel spacers

2-1/4″ (+1/4″ unthreaded nose) = Full length for custom cutting or open ended lug nuts

2″ (+1/4″ unthreaded nose) ½-20 ARP = Larger ½-20 studs for increased strength, made by ARP

Wheel studs are standard 7/16-20 thread unless specified.  Stud length is measured from face of hub flange without the brake drum installed.
