Like a standard OSR, but bigger! If you haven't already reviewed the standard OSR page, stop reading now and tap HERE to review the entire OSR page first.
The Extended Outboard Shock Relocation, aka the OSR+ kit, is the same as the standard OSR except that the hoop is 1.5 inches taller, which means that the entire shock body is mounted higher compared to the standard OSR kit. This results in one added requirement and multiple added benefits.
OSR+ Requirements: In order to clear the taller hoop, the OSR+ requires a body lift of 1 inch or more. If you aren't familiar with the concept of body lifts, or just not quite sure how to feel about them, tap HERE to read an article from Eimkeith. There are several benefits of running a body lift on the 3rd Gen 4Runner (aside from OSR+ compatibility), and Keith sums them up very well.
OSR+ Benefits: (pick one or the other, depending on build)
- (a) more ground clearance, due to higher mounting position top & bottom
OR
- (b) install a 14in shock instead of the typical 10 or 12in OSR shock options**
**12 Inch shocks are the safe limitation for stock rear geometry! 14in shocks or longer can only be safely used AFTER you have upgraded your rear geometry (with the FGP 3-Link for example). Upgrading the rear arms does NOT count as upgrading the rear geometry.**
We recommend consulting with Opt Offroad or checking out Opt's extensive OSR compatible shocks by following the link HERE, bypasses for this application also available HERE
DISCLAIMER: 2.5x14" 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.
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.
What's included:
- Upper extended shock hoops
- Upper shock mount tabs
- Frame plates & end caps
- Lower shock mount tabs (4Runner kit)
- Lower shock towers (Tacoma kit)
Options:
- Weld it yourself, or have it shipped pre-assembled for $200.
- Add reservoir mounts & hardware for $29.
- Add frame notch plates (for clearing 2.5" diameter shocks) for $29
Current Estimated Lead Time: 6-12 weeks for welded OSR kits
Lead times are subject to change depending on order volume. We will do our best to estimate and update the site regularly. As this is a "made to order" item, all sales are final.
