I am no mechanic and don't own an extensive range of tools, but I had this fitted in the car in less than an hour. I was a little worried that I had fitted it wrong, so I emailed the guys at www.4H-TECH.com. Within a few hours Patrick got back to me confirming everything was fitted correctly. The product seems very good and the customer service was fantastic. Thanks again Patrick

My short Shifter for my Astra J VXR/OPC arrived yesterday. I fitted it yesterday when it arrived. The difference from standard is night and day. It's an absolute blast to drive with. Thank you so much for a great product! Extremely easy to install, and its most certainly worth the money in purchase.
Thanks once again for your help when I called you about my address number not being entered on the order. Will definitely recommend your company in the future to anyone requiring a short Shifter.

Nah I fitted the 4H-TECH shifter last night, and can I say it took under 5 mins to do, Pulled one linkage arm off, undid 1 15mm nut, and just pulled mine off...... With a little wiggle . That's it!!!
Pushed new one on, did nut up and popped link back on.
And Wow wow wow lol, it's like a new box I kid you not.
Anyone thinking about it DO IT ... You will be amazed..
