(XT/HD Heavy Duty Series) Does not use our standard Upgrade Spring kit.

This kit is suitable for daily driving, street/strip, & full race applications claiming 550-650+ hp/ft lbs torque although in some full race applications, 1000 + hp ranges have used this kit with great success.

  • An XT/HD Upgrade Spring kit is sold separately & only by request. You will need to contact us if you believe you need something stronger than our "XT Series," (above 650 hp/ft lbs torque and quite possibly just some more extreme traction needs) and we will consult you if you need this kit. It is best to go with the XT/HD series kit that has already been assigned for your vehicle before requesting the upgrade to this series lsd kit.
