Review on Boost Performance with Timbren DVRRT Suspension Enhancement System! by David Bar

I bought this DVRRT kit instead of the air suspension because it has to be 100% reliable, it's a special rubber-like compound that should survive a minivan. The only tricky part of the installation is unscrewing one shock bolt (18mm) from each side of the minivan. The upper shock bolt has a nut that is difficult to access, so I recommend removing the lower shock bolt + nut. The screw is very tight, so be prepared to put in some effort to loosen it. Removing the spring and installing the DVRRT was easy (tip - watch the video on etrailer dot com). Then reassemble everything and be sure to tighten the shock absorber screw, done. It took me about 1 hour per side, taking my time with regular tools, but I bought an 18mm wrench because most metric wrench sets jump from 17mm to 19mm. My socket set had an 18mm socket. Now I can transport cargo from behind or in tow, and I don't have to worry about the van's nose hitting the stars.
