1 Top Rated Question

Is this an oil less shock or does it have to be lubricated at regular intervals? If so, what kind of oil should be used?

  • The QA1 Adjustable Rear Shock will not require any type of maintenance, however it is rebuildable/revalveable by QA1 directly, as well as QA1 Authorized Service centers.

    Great Product

    I think qa1 is the best shock going. They look incredible and so far perform as expected.

    Wow!!! Great way to get on the road!!!!

    The only problem i had with the instalation was that the measurement on the bottom of the shocks between the screw was shorter than the factory ones but I did the adjustment with two packing ring each side, I have a shelby gt 2007 vegas edition!!!!

    Worth Every Penny!

    These are fantastic! Just dial-in whatever ride quality you're in the mood for, and you got it. A number "2" setting drives like a Cadillac, the number "7" setting is noticeably stiffer. It's the best of both worlds at the turn of a dial. I haven't tried all the settings yet, but I'm thoroughly impressed already. The dial is easy to access too... I simply reach through my 5-spoke rims and turn the dial. I highly recommend these shocks. I wish I would've purchased them sooner. BTW... I have the Eibach Pro system springs, struts, and shocks (formerly). These shocks work very well with it. The number "7" setting feels just like the Ride quality from the Eibach Pro System.

    the QA1's feature a easily adjustable knob. if your wheel spokes are far enough apart you can just reach through the spokes and adjust the knob with out having to lay on the ground. there are quite a few adjustments as well for all types of driving. you can set it super soft for drag racing or super firm for corner carving.

    QA1s rock!

    These will make a very significant improvement to your launch. Easy to put on and adjust. Have not been to track with them yet, but can tell a big difference when taking off on the street.

    This product looks great as well as improvement

    I purchased this product for better traction on my vehicle which I supercharged and even with larger tires(305/35/20) and bmr lower control arms and relocation brackets was not able to hook up. The difference is night and day. The installation was about an hour and the fit and appearance and great. I would recommend this product for anyone who wants a great shock for a very reasonable price.
