Introducing our 3rd Gen 4runner OSR kit!
The problem: If you've ever worked on the rear suspension of a 3rd gen 4Runner, you know how frustrating it can be to remove/install the shocks. Unlike newer 4Runners, the 3rd gen’s rear shock mounts are tucked way up inside the frame. This limits the size of the shock you can fit. It also means that the shocks are mounted at an angle, which reduces shock efficiency and performance. Not ideal!
The solution: The OSR moves the shocks where they should've been in the first place, to the outside of the frame. It also comes with lower shock tabs that replace the stock lower mount. This allows for longer shocks, makes install and removal a breeze, and greatly improves the efficiency and performance of the shock! The cherry on top is that you'll be saving money on your shock purchase, since universal smooth body shocks tend to be much cheaper than "factory replacement" shocks.
The OSR improves on other outboard kits in more ways than one. In addition to the higher strength DOM steel, our kit utilizes frame plates to add load bearing strength at the mounting points, as well as radius’d upper mounts to give more weld surface and strength than your typical outboard hoop. This kit was built to outperform the competition, plain and simple.
Our OSR is designed to be compatible with 10-12" smooth body shocks.
To increase ground clearance or run a longer 14" shock, check out our OSR+ HERE!
For 2.0 shocks, a minimum 3.5” wheel backspacing is recommended for tire clearance. Example: if you have 4.5” BS wheels, you will need 1” spacers to bring it down to 3.5”. 2.5in shocks require minimum 3" backspace. Results may vary.
DISCLAIMER: 2.5x12" diameter "off the shelf" shocks WILL NOT work for this application as they are commonly longer collapsed than an off the shelf 2.0" diameter shock. Frame notching will be required as well.
