Must only be installed on vehicles covered by the FIAT Authorization, and in any case that aren’t fitted with an ESP (Electronic Stability Program).
1. Lifting the vehicle
Lift the rear of the vehicle slightly using suitable jacks positioned in the lifting points to guarantee the safety of the operation and to avoid damaging the chassis: you don’t have to take all the load off the rear suspension, it’s enough to let the wheels down enough to be able to insert the air springs.
2. Fitting the suspension units
Unscrew the end of stroke buffer. Fit the top support of the AIR TOP (figure 2) in its place using the M10 x 1.25 x 25 screw and the flat washer supplied (torque down to 53 Nm) applying thread locking compound.
Position the pneumatic suspension correctly (red hose on the right, black hose on the left) so the bottom part rests exactly on the galvanized plate between the two U-bolts of the leaf springs (figure 3). The two parts of the clamp must clamp onto the protuberances of the above plate when the two round-headed M8 screws are screwed down (torque down to 27 Nm); this guarantees the correct positioning and fixing of the bottom part of the suspension. The top part is fixed to the support that was previously mounted with the two M10 x 1.25 x 25 bolts, with the screw inserted from the bottom and the nut on top. (torque down to 53 Nm).
3. Installing the hoses
Fix the red and black connecting hoses along the underbody with the PVC clips supplied, keeping the hoses away from the exhaust pipe and any moving parts. To cut the hoses to length before Inserting them In the fittings of the inflation control unit, use the relevant blade (Stanley knife type) to obtain a perfectly perpendicular cut and avoid deforming the hose or creating grooves at the end, which could cause pressure leaks.
4. Installing the control unit
We recommend Installing the Inflation control unit in a position where it is easy to reach so It Is easy to check and reset the pressures of the suspension units, but also In a place where It is protected from accidental knocks. The envisaged position is on the panel of the base of the driver’s seat, under the parking brake lever. In this case the hoses can be fed into the driver’s cab through the existing hole for the parking brake cable. One of the two fittings for the hoses has a red reference mark to show which way they should be connected.
