Never adjust ride height using the spring perch. Our systems are designed to adjust ride height via the lower mount. We recommend you remove the coilover system from the vehicle to adjust ride height, as it is necessary to use force when tightening the locking collar on the lower mount.
Make sure the spring perch (B) and locking collar (C) are locked by using the spanner wrenches and turning them in opposite directions so they lock against each other. Next, loosen the lower locking collar (D) and spin it up the amount you want to lower the car (for example, if you want to lower your car 2” then spin the collar up 2”). Now use the spanner wrench on the spring perch (B) and begin turning the perch clockwise. This will thread the entire shock assembly further down into the lower mount (E). Once you adjustments are completed, tighten the lower locking collar (D) in place against the lower mount. If you need to raise your car, follow the same steps except turn the shock assembly counterclockwise.
For vehicles without an adjustable lower mount, use the spring perch to adjust ride height. By lowering the locking collar (C ) and spring perch (B) the suspension is allowed to compress. This will result in a lower ride height. After your adjustments are made, tighten the spring perch and locking collar together using the spanner wrenches. Most vehicles without and adjustable lower mount will make use of Helper Springs.
For vehicles with a separate spring and shock, part (A) is used to adjust ride height. After desired ride height is reached with the spring, it is extremely important to adjust the length of the shock by adjusting (B) to your desired position. The last step is to install the wheels and put the car on the ground and move the vehicle 20-30 feet to allow the suspension to settle. Then adjust (B) to let (C) compress 1/3 of the way into the strut and leave 2/3 of the shock shaft outside the strut; then tighten the locking collar against the lower mount. Use of a ziptie or black marker may be useful in judging how to make sure 1/3 of the shock is in the strut. Failure to set the shock stroke correctly will result in damage to the shock and void the warranty. For safety reasons, at least 30mm of the lower mount should be threaded onto the shock.
