ACR Racing Suspension
ADJUSTINGOn vehicles with the ACR suspension, the lower spring seat can be lowered or raised to adjust curb height. Use the following method to obtain correct curb height.
1. Raise the vehicle to release the tension from the shock assembly's coil spring. Refer to Vehicle Lifting.
2. Remove the tire and wheel assembly.
3. Using two adjustable pin spanner wrenches, one on the lower spring seat, holding it steady, and the other on the lock nut below it, loosen and back off the lock nut.
4. Using one of the adjustable pin spanner wrenches, rotate the lower spring seat in the direction needed. Note the amount the lower spring seat is rotated. Marking the original spring seat location with a marker or paint may help.
- If the vehicle was lower than curb height specification, rotate the spring seat upward.
- If vehicle was higher than curb height specification, rotate the spring seat downward.
5. Once the preferred spring height is achieved, thread the lock nut up against the bottom of the lower spring seat.
6. Place an adjustable pin spanner wrench on the lower spring seat to hold it in place and another on the lock nut, then tighten the lock nut up against the lower spring seat.
7. Install the tire and wheel assembly. Tighten the wheel mounting nuts in the proper sequence until all the nuts are torqued to half specification. Repeat the tightening sequence to the full specified torque of 122 Nm (90 ft. lbs.).
8. Lower the vehicle.
9. Measure curb height. Refer to Curb Height Measurement.
