the bottom sleeve of the front rotator with grease through the grease
fitting. If you have the poly bushed front mount, keep the bushing greased through
the grease fitting using synthetic silicone grease (our Part #902).
• Re-install your driveshaft. Our driveshaft loops meet the build and location
specifications required by the NHRA and IHRA.
• Ford 9” Rears: You will notice that the rear mounting bracket of the torque arm has
two sets of mounting holes. On the 9” rear you want to use the set of mounting holes
that are towards the driver’s side of the car. On a stock rear or 12 bolt rear, you would
use the set of mounting holes towards the passenger’s side of the car. The reason for
this is that on a 9” rear, due to the larger center section, the torque arm mount on the
rear is actually 1” further to the driver’s side of the car compared to the OEM rear.
Using the set of holes towards the driver’s side of the car in our rear mounting bracket
will move the torque arm back to the OEM location and line it straight up with the front
mount. If your 9” rear is equipped with a nodular (large ribbed) center section, it may
be necessary to grind away part of the rib so it does not interfere with the torque
arm’s rear mounting bracket.
