Learn to rebuild a QA1 twin tube shock in just minutes for cleaning or replacing parts. These shocks are oil-filled and use a gas bag instead of being gas charged. Watch Marshall take apart and put back together a shock absorber that is rebuildable and revalveable.

It's a really cool image.

@juanfarello4676 5 лет назад

Really cool explanation, after watching this I have a more clear idea, in my case happened that the tube had some air and messed with the correct function of the shock. One question, should i use hydraulic fluid with more density? Now I'm using shell spirax s1.

TECH TIP: Rebuilding a twin tube shock is a little different than rebuilding a monotube. Here’s a video with Marshall showing you how.

Wonderful explanation brother.I just want to know what kind of oil is used and how to rectify a base valve problem

I disassembled my shock this afternoon because it was leaking again. This is the third time that I would be sending it in to be rebuilt. I wanted to see what was inside it. Mine has an o-ring around the compression tube that is not shown in this video. Where does this go on the tube? It was about centered on the length of the tube. I am giving up on the coil over shocks and going back to coil springs and conventional shocks.

When did Qa1 change from the closed cell foam pad to the gas bag? This morning, I tore down a pair of 50 series twin tube shocks that are over 20 years old that still have the foam.

@danc2014 3 года назад

Was this just a clean and oil replacement? Where was the rebuild part? New valve rings G disk? What part are used for the rebuild?

Hi Mauricio! It would be best to contact our support team and they would be able to help you out. You can reach them at 800-721-7761 or sales@qa1.net. Thanks!

@eniteekpolo5360 7 лет назад

did you introduce compress air as you did on the mono tube?

@QA1TECH 7 лет назад

Hello. The gas bag accommodates for the volume of the piston rod in a twin tube shock, so no compressed air is required. Thanks!

@jebuzqshaze695 2 года назад

Hello, I am writing to you from Santiago de Chile and I have some adjustable gaz shocks and the liquid is lost through the stopcock, could you guide me in opening the stem. for a repair as it makes it difficult for me to send them to the factory. Greetings.

@naderachkar1231 3 года назад

@green1394 5 лет назад

@AndrewLngn Год назад

It is likely qa1 premium shock oil.

@punto755 5 лет назад

What is the gas bag and what is it for ?What if you dont put it ... ?Thanks !

@AndrewLngn Год назад

The gas bag is there to accommodate for the displacement of the shaft as it enters and exits the shock body.

@debeerpaul 4 года назад

@J J Only if you want to reduce the posibility of getting a good squirt of oil shot into your eyes or have baby struts. The steel toe boots are good to wear at all times even when jogging a marathon in the rain.

Iso 46 oil???

@pargatsinghchandi5381 Год назад

How shock oil

@mieamirrol5240 6 лет назад

Is there a measurement for the oil in the shock?? If is, what is the difference if we put more or less oil in the tube?? Tq

@QA1TECH 6 лет назад

No there is no measurement for a twin tube shock. You don't want any air pockets in there as it would create problems with the performance of the shock.

@mieamirrol5240 6 лет назад

QA1 thanks for the answer
