The problem: If you've ever worked on the rear suspension of a 3rd gen 4Runner or 1st Gen Tacoma, you know how frustrating it can be to remove/install the shocks. Unlike newer models, the older generations' 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 smoothbody 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, the FGP 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. Also, many outboard kits simply move the shock mounting location without increasing actual suspension travel. On the other hand, the OSR is designed to achieve as much suspension travel as possible within the safe limitations of factory suspension geometry.

The OSR is designed to be compatible with any spring and smoothbody shock with a 10” or 12" stroke, though the ideal OSR setup will be a 12” shock. For 4Runners, tall springs (LC 7 or 8 wraps for lighter trucks, OME 861s for heavy trucks), DuroBumps 5.25” and Opt Offroad rear control arms (uppers are most important in this case). For Tacomas, a taller leafpack (or at least an add-a-leaf), and a set of DuroBumps 4.25". A 10” stroke shock works, but will sacrifice wheel travel and is only recommended for 0-2” lift. A 2.5” diameter shock is best, but will require frame modification and potentially more wheel backspacing. 2.0" diameter shocks do not require frame modifcation. 2.5" shocks also usually have longer extended/collapsed lengths that you will have to contend with (or go with a 10" stroke vs a 12"). If you order 2.5 Radflos from us, we will custom order them with the ideal collapsed and extended lengths for the OSR. Frame notch filler plates are also included with your purchase of 2.5 OSR shocks when you buy them through Opt Offroad!

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”.

What's included:

• Upper shock hoops

• Add reservoir mounts & hardware for $29.
• Add frame notch plates (for clearing 2.5" diameter shocks) for $29*

Current Lead Time:

WIY kits: 3-4 weeks. Preassembled kits: 4-6 weeks. ALL SALES FINAL.

*If you purchase 2.5" shocks with your OSR we will reimburse you $29 for the frame notch plates. If you have already purchased the shocks, or come back to purchase them at a later time, let us know and we will apply the $29 credit to your most recent order!

If you would like to arrange for pickup and/or install at FGP in Montclair, please let us know in the order comments (or contact us afterwards) and we will reimburse shipping or apply it as a credit towards install cost. Thanks!
