View Full Version : Rear Air shocks to regular shocks?

11-19-08, 10:43 AM
My rear air shocks are leaking and I would like to replace them with regular shocks. Any problems in doing this? Somehow I would have to bypass the error codes from not having my air shocks or leveling system.I am looking for something that offers a smooth ride-not interested in a stiff ride. Monroe sensortracs have been mentioned before-any ideas are appreciated-thanks!

i heard that those for pontiac gto 2004 till 2006 work and our cadis so you can try them. the price is around 35 dollars for each one. just pull out your control panel and pull out that fuse from the control level easy cake..:stirpot:

Just to warn you be carefull with how much you load your car... because with those new shocks the rear will sit lower when loaded... my buddy and his GTO shocks 2 ppl in the rear seat and the back end sits way lower then before.. .mine has the leveling shocks in the rear and even with 3 peopl in it you cant even tell the extra load...

For witner I use 2 bags of salt and 2-45lb steel plates for extra traction... and you cant even tell the extra weight!>..

Thanks for the info-guys! I guess I will go with the Monroe Air shocks in the back. I will order them and try to install them in a couple of weeks. Do you know of any problems I will run into? Next year I will tackle the front struts and bushings. Thanks for the help!

I replaced my blown rear air shocks with stock GTO shocks, Monroe sens-a-trac units from rockauto. It came to roughly $60 shipped for both. Far cheaper than the $80+ each for the air shocks.
The GTO shocks came with bushings that seemed too small for the shock tower opening... the steel spacer sleeve on top of the Catera shock was rust fused onto the Catera shock. The Catera shock mount bushings were too "loose" on the shock mounting stud without the sleeve, so I used the GTO shocks + bushings without the sleeve, which it seems they were meant to be used without. The mounting stud on the GTO shocks also seems to be too short no matter what bushings were used. I had to have a friend push up from under the car as hard as he could for me to get the nut started inside the trunk. It could just be because the bushings were new. Once I got the nut started and tightened down there seemed to be no issue.
I have since driven about 4000 miles with no issue, knock on wood.
My intentions were to get new spacer sleeves like the stock Catera shocks had and fit them with the Catera replacement bushings that seem more form fitting to the shock tower, but motivation is low with the cold weather here and not much room or time to work on the car.

I replaced mine with the gto rears and had no mounting issues. Bolted right up with no noticable diffrence from the stock ones, and zip tied the little level sensing arm in the up position to keep the air pump from knowng things were off. Worked perfectly.

Just Suday I had to tow my street bike on the trailer with 3 people in the rear (5 in car total) and it worked fine. May have "looked" lower but did not bottom out or have any real issues. The gto shocks are not harsh but are a much needed upgrade in my eyes.
