Rear Smoothbody Shocks (for OSR)

So you're going with the FGP Outboard Shock Relocation, good choice! But now you have a dilemma: which shocks to go with, and when can you get them? This page clears it up.

The OSR was built to work with a 2.0 or 2.5 smoothbody shock with a 12 inch stroke. "2.0" or "2.5" refers to the diameter of the shock body (in inches), and stroke refers to length of the shaft travel. 10 inch shocks will work for stock height applications. Some 2.5x12 shocks are longer than ideal (the larger diameter bodies are also longer than their 2.0 counterparts) and will require extra work in some cases. However ALL Radflo shocks are built to spec with the ideal lengths and reservoir layouts specifically for the OSR. If you want 2.5 shocks on your OSR, your safest/easiest choice is Radflo.

Prices are PER PAIR, not per shock.

FAQ:

Are these prices for one shock or two? The prices are PER PAIR. You only have to add one quantity or “item” to the cart to receive two shocks. Message or call us if you are in need of a single shock for any reason.

Which shock diameter should I get, 2.0 inch or 2.5 inch? This kit is only recommended for 2.0 shocks for two main reasons. 1: There is very limited clearance between the inside of the tire and the shock body at full stuff (tire into the wheel well), and will potentially require a wheel spacer EVEN WITH A 2.0 SHOCK. 2: There is very limited clearance between the frame rail and the shock body when the the tire is articulated at full droop. Running anything larger than a 2.0 smoothbody shock WILL require notching the frame (cutting and re-welding it further inboard). Note: frame notch filler plates are also included with your purchase of 2.5 OSR shocks when you buy them through Opt Offroad!

Which shock length should I get, 10 inch or 12 inch? The OSR is designed to be compatible with any spring and smoothbody 2.0 shock with a 10” or 12" stroke. The ideal OSR setup will be a 2.0x12” 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 works, but will require frame modification and potentially more wheel backspacing. 2.5" shocks also have longer extended/collapsed lengths that you will have to contend with (or go with a 10" stroke vs a 12"). Just keep in mind that everyone's setup will differ depending on how you set up your lower shock mounts, and you will need to check your pinion angle at full droop to see if limit straps are necessary. (if you are lifted and still running stock rear arms, you should consider upgrading to a set of our adjustable uppers so you can correct that pinion angle!).

Which shaft size should I get, 5/8 or 7/8 inch? What are you going to be doing with your truck? Mostly pavement, light wheeling with occasional rock trails and desert trips? 5/8in shafts should cut it. Anything beyond that and 7/8 is probably the way to go. The amount of weight you carry in the rear of the vehicle is another important factor. Extra tools and parts, steel bumper, spare tire carrier, spare gas tank? Towing with it? 7/8in shafts are definitely a good idea. After all, these shocks are rebuildable, you'll likely have them for a while. Get what you need the first time, so you don't have to swap shocks later.

Which shock brand should I go with? That is mostly personal preference, but there are some factors to consider. Prices are relatively the same across each brand, but they all structure their options a little differently. Those options are really what change your price, far more than the brand themselves. Make sure to check the lead times as well as the "in stock" items, to help you make your decision. The last thing you want is that pretty OSR sitting in your garage for months while you wait for your shocks to show up!

Tip #1: Not all options and/or combinations apply to all shocks. If a certain shock combo is "unavailable" try messing with the options a bit!

Tip #2: Radflo Shocks will build and tune your shocks specifically for your build and driving habits, free of charge. Keep that in mind when comparing prices, and what you're getting for your money! "How does it work?" After your Radflo purchase, we will email out a simple Tuning Questionnaire  for you to fill out. Your answers get attached to your order, and Radflo valves your shocks accordingly, to get you the best performance and ride quality possible. Huge value, and worth the wait!

Tip #3: If you are looking at Fox shocks with compression adjusters, keep in mind that Fox 2.5in shocks come with dual adjusters, and 2.0in shocks come with singles.

Tip #4: King 2.0 and 2.5 shocks come with 7/8in shafts. 5/8in shafts are not available from King.
