QA1 monotube circle track shocks are racer rebuildable and revalveable. Learn how to rebuild a QA1 monotube shock absorber in just minutes to clean the shock or replace parts. www.qa1.net 800.721.7761
TECH TIP: Many QA1 shocks are designed to be rebuilt and revalved by racers. Check out our video on how to disassemble and reassemble your monotube circle track shocks.
Hello dear, I write from Chile. I want to rebuild my Bilstein PSS10, but can not find the charging valve nitrogen. can you help me to tell me where the valve Thank you so much regards
The gas pressure in the shock depends on the compression valving of the shock. The stiffer the compression valving, the more pressure that’s required. For 26 series shocks, set the pressure regulator on your nitrogen tank to the following pressure: Compression Valving PSI 1 100 2 100 3 100 4 100 5 100 6 100 7 125 8 150 9 175 10 300 11 300 12 300
It depends on the valve fitted to the shock, but we use either a Schrader valve fill tool or a Hyperscrew fill tool. Here's a link with more info: www.qa1.net/suspension/circle-track-shock-accessories/monotube-schrader-valve-fill-tool
Sorry, but I'm not familiar with Tein's construction or if rebuild parts are available. I replied to you on Facebook as well with a link to our authorized rebuilders. You could try reaching out to one of them to see if they can be of further assistance. Also, Feal Suspension might be another resource you could look into. Thanks!
+eezuan othman It depends on the compression valving of the shock. We use 100 psi for up to a 6 valve, 125 for 7, 150 for 8, 175 for 9 and 300 on 10, 11 and 12. You can call our tech line at 952-985-5675 if you have any other questions.
A Hyperscrew is a QA1 Exclusive gas sealing screw. Through the Hypercharging process, nitrogen gas pressure is retained inside the shock by the Hyperscrew. If you have any other questions, feel free to contact us at 800.721.7761.
