Great info and well delivered. I'm a Mech/EE engr, use to have a Jeep Wrangler and wrench on all my cars based on previous experience and good / accurate info that can be found on the Internet, including You Tube. Now that I'm an owner of a GX platform, I'm finding that there are some not so "good" / and potentially inaccurate info from people wrenching on their Toyota/Lexus platforms. However, as I watched a few of the Metal Tech videos, I'm very appreciative of the accurate and fundamentally sound information you are providing to enable the community to work safely on their rigs to achieve a fundamentally sound mechanical / electrical outcome. Well done fellas, I really appreciate it.
Since the MT4X4 springs come in two rates you have some choices. MT4X4 medium LT springs provide a much softer ride and for lighter builds, yet still give you the full long travel free height. The MT4X4 Heavy LT springs, as well as the ICON springs, are for a heavier build. However the MT4X4 springs are made to have a taller free height for long travel use. ICON springs are a good option for heavy loads if one is not using a long travel set up.
Agree it is easier to "disconnect" the lower shock, yes. However it is very difficult to "install" the sock if the top is already installed. The shock mount angles downward, if the top is attached you have to swing the shock onto the mount that is facing downward. This is especially difficult with a shock with a bushing lower mount vrs. a bearing found on higher end models. This is why we always install the lower mount first, then use the shock body as leverage to twist the bushing/bearing so the top mount can be installed.
