Metal Tech 4×4 GX470/GX460 Rear Long Travel progressive rate coil spring.
This progressive rate spring will give you a total of 27″ of articulation when combined with our custom made FJ Cruiser/4Runner Icon 2.0 VS Series Shocks, FJ Cruiser Rear Extended Brake Lines, and Metal Tech 4×4 3″ Bump Stop Drops Extensions. When we first installed our Total Chaos FJ Cruiser 2″ Long Travel Kit we were so impressed with the increased suspension travel and ability to fly through the whoops at high speed the rear axle couldn’t keep up! One of the biggest disadvantages of the GX470/GX460 is the limited suspension travel.
Since Lexus does not capture the coil spring the suspension travel is limited to the free height of the spring (ie the total length of the spring) before the spring will fall out of the coil buckets. By creating the dual rate spring we have the bottom half the spring do all the suspension work and the top half stays fully collapsed at ride height. When the suspension starts to cycle downwards the top half of the spring starts to open up allowing for greater suspension travel over a standard 2″ lift spring.
Metal tech 4×4 Next Gen dual rate Long Travel rear springs. We have taken the knowledge and performance we have gained over the past several years of our long travel systems and wrapped it into the single best performing Next Gen spring to date.
