Select Front Struts

IMS front struts have a fully threaded body to set the lift height. Usually set to 213mm letting the coils do the lifting, or set to 226mm and used with 2" coils to get 3" of lift due to taller coil seat height.

Need to Convert from Airbags to Coils?

Dobinsons airbag to coil conversion kit is what you'll need. This kit adds 1/2" to listed coil height

Select Rear Shocks

Only those people looking to do a full long travel rear can order the ***575 shocks. They will cause issues if you don’t have the correct replacement brake lines, bump stops, and sway bar links in place.
KDSS vehicles CANNOT use long travel rear shocks
IMS59-50701 - IMS non-resi monotube light to heavy loads (0-3" lift)
IMS59-50575 - IMS non-resi monotube for LONG TRAVEL only, not for KDSS
MRA59-A701 - 3-Way Adjustable Remote Resi monotube shocks (0-3" lift) - adjust the valving if your load weights vary for trips, towing, etc
MRA59-A575 - 3-Way Adjustable Remote Resi monotube shocks LONG TRAVEL only, not for KDSS - adjust the valving if your load weights vary

Add Front Brake Lines?

Replacement brake lines aren't required for the front of this vehicle, however adding stainless braided brake lines front and rear will increase the pedal feel and braking performance

Add Extended Rear Brake Lines?

If you've chosen the **575 Long Travel rear shocks, new extended rear brake lines are required with these shocks

Add New UCA's?

New Upper Control Arms (UCA's) can greatly increase the quality of the wheel alignment, mainly in the caster setting, improving steering and handling. Should be used for 2.5″ or more of lift. Select one, the click on small box to the right for more full specs

Add a Diff Drop Kit?

Diff drop kit is for 3″+ lift to reduce the CV angles

Add New Strut Mounts and/or Assembly?

Here you can add new strut mounts and hardware, or also have the struts pre-assembled prior to shipping

Assembled Coil Seat Height

If you've chosen to have the struts assembled, select what coil seat height you would like. Standard is 213mm and only the coils do the lifting. Raised adds 1" of lift when set to 226mm, so using a 2" coil with the raised seat height gives 3" of lift, for example

Add Front or Rear Lean Correction Spacer?

If your vehicle already leans to one side, add this to the low side during assembly. KDSS vehicles should use a rear spacer at a minimum if lifting 2" or more. A 1/4" front spacer adds 1/2" of lift. Rear is 15mm (1/2") of lift.

Add Rear Panhard Rod?

For lifts of 3" or more, a heavy duty adjustable panhard rod will allow you to re-center your axle. This can also be used with any height, but for those needing a stronger panhard rod than stock

Add New Front High-Clearance CV Boots?

If your vehicle is older, and you plan to lift 3" or more, new high-clearance CV boots are a great option

Add Front Swaybar Relocation Bracket Kit?

Moves the stock front sway bar mount forward for better clearance to the coilover, ideal when lifting 2" or more

Add Extended Front Swaybar links? (only non-KDSS vehicles)

Factory sway bar links are prone to bending and breaking and can even puncture your CV boots. All-Pro's heavy-duty Toyota front sway bar links replace the weak stock links using top quality Teflon lined 3/4" Heim Joints and hefty .156 wall DOM tubing.

Add Extended Rear Sway Bar Links? (only non-KDSS vehicles)

For 2" or more, the stock sway bar angle is out of alignment and inhibits proper articulation and comfort. Adding longer links corrects this

Add Front Bump Stops?

If you regularly offroad, extending your bump stops helps reduce the harsh impact when the front bottoms out. Click the small box to the right of the product for more information.

Add Rear Bump Stops?

For those who regularly offroad and stand a chance to bottom out more often, or for those running the 575 long travel shocks, new bump stops should be added

Add Rear Trailing Arms?

For heavy offroading, or for true long travel, new upper and lower adjustable trailing arms help correct pinion angle, give better articulation, and are much much stronger than stock

Add Airbags?

If you regularly tow with your vehicle, carry a motorcycle on a hitch mount, or have huge variances between daily weight and loaded trip weight, a set of Firestone helper air springs will be very useful. Inserts inside your rear coil springs to add additional load support, Manually inflate or deflate the air bags to add or remove support or height.
Firestone 4135 is for 0-1.5" of lift
Firestone 4108 is for 2-3" of lift

Upgrade Front Brakes?

This is not required with the suspension, but considering that when adding a lot more weight and rolling mass to the vehicles, the stock brakes aren't doing the job they're supposed to. Adding the Powerbrake D-Line Rotor and Pad kit gives bolt-on excellent performance without needing to replace so many parts. Or go all out with the X-Line Big Brake Kit and add massive front stopping power with new 6-piston calipers, brake lines, pads and rotors (requires 17" wheels)
Sport versions have 13.3" diameter calipers, regular are 12.55". You must verify that size before ordering

Designed, developed and tested in Australia by Dobinsons Spring & Suspension, in-house suspension design engineers, our 4×4 shock absorbers and coil springs are designed and tested to perform in the harshest conditions right across the world. As we export to over 40 countries worldwide from their Australian head office, the importance of quality is at the forefront in the complete design and manufacturing process. This ensures every shock and coil spring can withstand the blistering heat and corrugations of the Australian outback right through to the subzero temperatures of a Russian winter.

Dobinsons IMS monotube shock absorbers are designed for next level performance over twin tube shocks in those hot, harsh, demanding conditions. By utilising the monotube design, Dobinsons IMS shock absorbers are able to resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.
The larger 50 and 60mm high flow pistons reduce internal pressures, reduce the heat generated, transfer heat to the body for faster cooling and offer improved damping performance and vehicle control at higher shaft speeds on rough terrain and during big impacts. Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling. The micropolished, hard chromed and heat treat shock shaft, CNC aluminium high flow race inspired piston, and DOM seamless tubing body provides the ultimate in performance and off-road durability.

Composite piston wear bands, high quality Fuchs oil and a race style 3-stage sealing system offer the lowest levels of friction whilst maintaining durability and longevity without the need for frequent rebuilding or servicing. Dobinsons team of engineers spend hundreds of hours of testing and tuning the shim stacks and damping Characteristics in each IMS shock to ensure a balance of comfort, handling, vehicle control and off-road performance – Enjoy the ride

We proudly manufacture the highest quality replacement coil springs for many different applications, complying to ISO9001:2008 international quality standards from our state of the art manufacturing facility in Central Queensland, Australia.

All Dobinsons™ coil springs are load tested and scragged 100% to eliminate subsequent spring sag. We also perform spring fatigue and hardness testing using in-house state of the art testing equipment.

***2.5″ or more of lift, new UCA’s are recommended***

NOTE: For a dobinsons toyota 4runner ims lift of 3″ in the rear, new extended brake lines and minimum of 2″ bump stop extensions are required to be used with our long travel rear shocks. At full extension, the stock brake lines could get damaged, and with stock bump stops in place, the shocks will bottom out before the bump stop fully engages, which will quickly destroy the shocks.
