Now available with remote reservoir rear option on every length!

Please read: normal shocks can be up to 6-8 week lead time: Remote Res Rear (RRR) orders are subject to an additional lead time

This is not an 'off the shelf' upgrade part; the 4600 series is the top tier stock replacement shock. These shocks are much softer than stock. 

Going beyond just stock replacement we've spec'd out 5100 series that will work on the Montero and other 4wd chassis and we provide a longer than stock travel set to work with your lift kit or modified suspension. if you're running our custom long springs you can use these, if you're running most other aftermarket springs with a spacer, you can use the mid travel, for anyone with OME, dobinsons, etc, run the stock length 5100. We know, we know, you have "x" amount of lift, but it's not about the lift, it's about the suspension geometry, your springs will unseat if you're running anything other than our long springs with the long travel shocks, if you run the long travel shocks you will also need a long travel rear brake line or your stock brake line will now be the limiting factor. Long story short, you cant just buy our long travel shocks and have a long travel suspension. We know people like to tailor their own suspension so we sell these as a set but if you have any questions about your suspension geometry, just reach out to us and we'll get you on the right track. Your rear lower bolt will no longer have a bushing so replacing the nut with a nylon lock nut or using thread locker during install is reccomended. The front lower shock mount can often be bent tighter than the lower bushing so it can require retweaking, but these are the best fitting 5100's available currently.

About the 5100 series:

Softer than the 4600 - softer than you might expect.   Our 5100's are valved primarily for off-road washboard driving, soaking up rocky roads and rugged terrain mile by mile. The kind of environment that involves low tire pressure and speeds up to 50mph most of the time. On the street you'll notice the ride is far more compliant than stock with more body roll and a little more carryover than a street performance shock. We've tested every available brand of shock for stock replacement and went a step further to ensure the smoothest and least jarring ride you can get off-road without the huge price tag. These shocks ride in a manner that will make you very comfortable at low speeds, higher speeds can involve more suspension cycling than OEM replacement shocks, if any of this concerns you, we suggest ordering out 4600 series shocks or checking out our combo breaker kits for fine tuned set-ups with descriptions of use. 

Adventure Driven Designs' Bilstein 5100 Kit will provide increased wheel travel on stock and lifted Monteros of up to 2.5" of lift. The addition of the rear remote reservoir adds sustained dampening as the rear cycles significantly further and more frequently than the front of the vehicle.

Where else can you get a Bilstein 5100 Kit for your Montero?


We’ve custom spec’d 5100 series Bilsteins to make your truck ride like you’ve never experienced before. We kit these in house for the best fitment. You're getting the only Bolt-On 5100 series upgrade currently listed to the public for a Montero, exclusively from Adventure Driven Design.

Rear Shock Options:

These come in three sizes.   Why three?     Your rear coils are held in place by interference fit that's limited by the shock's extended length.   If you put longer shocks on without longer springs, you run the risk of a spring falling out of place - Adventure Driven Design is not responsible for this as you modify your truck at your own risk. Think it through.    

  1. Stock length
    This is the right choice for you if you're running stock coil springs or Old Man Emu springs which aren't built to increase flexibility.   
  2. Mid-travel for increased articulation without going HAM. If you remove your sway bars you may need to adjust your brake hose brackets, get our extended brake line, adjust ABS sensor wires, parking brake cables, etc - in other words this is definitely for advanced installers and you are absolutely responsible for yourself when installing these longer-than-stock shock absorbers.  Great for experienced wheelers who ditch their sways and want to get the most of their suspension flex. OME Springs with a spacer call for this kit.
  3. Long Travel
    They're as long as we could make them without the risk of them bottoming out when fully articulated. You do run the risk of binding with these, it's suggested you run poly bushings in your trailing arms to keep bind at a minimum. ADD is not responsible for any damage done from inexperienced users running these shocks, you may need to adjust your brake hose brackets, get an extended rear soft line from us, adjust cables, etc, do stuff, take precautions... you might even convert the front of your trailing arm from bushing to a joint of some kind, These shocks are intended for off road rock crawling. You can build a very nice and capable daily driven rig, or you can go full trail mode on a budget. Whatever you're doing, you're deep in the modified suspension world so put on your thinking cap and get to work! Or turn your butt around and go back to the stock replacement ones, this isn't for the faint of heart. They will cause accelerated wear on the factory rubber bushings from cycling the suspension off road.
  4. Now with additional rear remote reservoir option! Why only the rear? If you observe the drive-line and suspension geometry of the Dakar winning Montero; you may find that the front has a limited amount of travel with the primary traction force driving from the rear of the vehicle. The rear coil sprung, trailing arm retained and panhard controlled system allows for significant cycling and a long distance of travel when compared to the front. Long story short; the front just doesn't need it as much as the rear. We're all about providing exactly what's needed and nothing more. Keeping off-road expedition-level suspension available to the every-man.

These shocks are always special order. We no longer guarantee they'll be built up, sitting on the shelf in advance. They sell as fast as they're made these days. Please be patient. Due to our website configuration, these have to show as 'in stock' in order for you to be able to add to cart, apologies in advance for any confusion this may create when ordering. Please read this carefully.
