Select Front Coils
OE spring rate on a V8 GX460 is 730LB (same as the C59-350, 352,354). Lighter than stock springs shouldn't be use unless you want it softer than stock, which will increase nose diving while braking.
Stock weight = all stock front end | 110 LBS is usually a slim line bumper and winch with synthetic line | 220 LBS is usually a full width steel bumper with a winch and synthetic or steel line | 300+ LBS is usually a full with steel bumper, winch, dual batteries, and skid plates
C59-300 - 1.5" with stock weight (comfort spring rate)
C59-302 - 2.0" with stock weight (comfort spring rate)
C59-314 - 2.5" with stock weight (comfort spring rate)
C59-350 - 2" with stock weight, 1.5" with 110-220lbs weight

Select Front Struts
IMS59-50700 is to be used with any lift height 0-2.5", the coils give the lift. IMS59-50574 is an Extended travel strut, that can add up to 1" to coil spring height to get 2-3.5" of lift, depending on coils used
IMS59-50700 - IMS non-resi monotube, adjustable height (0-2.5")
IMS59-50574 - IMS non-resi monotube Extended travel (2-3.5" lifts), coil seat set higher to add up to 1" extra lift
Select Rear Coils
Discard passenger weight. Weight listed refers to additional product weight such as roof rack, drawers, rear bumper, swing out spare, etc. For most coils, 100lbs of added weight drops the rear by about 1/4"
Vehicles with KDSS lifting 1.5" or more should add a PS59-4025 trim spacer for the passenger side
C59-323 - Stock height up to 1/2" lift
C59-599 - 3/4-1" with stock weight

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
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 3"+ LONG TRAVEL only

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 3"+ 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 3"+ LONG TRAVEL only, not for KDSS - adjust the valving if your load weights vary for trips, towing, etc
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
Add a Diff Drop Kit?
Diff drop kit is for 3″+ lift, or when using 574 long travel struts to avoid CV bind at full droop
Add New Strut Mounts?
If you want to add new front strut top mounts so you don't have to separate the old coilovers and reuse the mounts, add that here
Add Front Strut Assembly?
If you want the front coils, struts and new strut mounts (must be added above) to be assembled prior to shipping, add that here
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. 220mm adds 1/2" of lift. 226mm adds 1" of lift, so using a 2" coil with the 226mm raised seat height gives 3" of lift, for example
Add Front Swaybar Relocation Kit? (only non-KDSS vehicles)
The Dobinsons front swaybar relocation kit repositions the front sway bar (non KDSS models only) for proper clearance and working angle when lifted 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 KDSS Spacers?
When lifting the vehicle 2" or more with KDSS, the KDSS Spacer Kit from Treaty Oak Offroad will need to be added to level out the sway bars front and rear to balance the vehicle (removing lean) and also provide additional wheel travel without the KDSS system limiting the suspension travel.  This spacer kit bolts between the original sway bar mounts, 1 on the front and 2 on the rear.  Some trimming of some skid plates up front may be required if they don't allow enough clearance for the sway bar at full droop with the Treaty Oak Spacer kit installed.
This is a requirement for any 3" rear lift.
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 Panhard Rod?
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 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 Rear Trailing Arm Skids?
Protect the vulnerable rear lower link mounts on your vehicle with a pair of lower link skids from RCI Metalworks
Add Rear Lower Shock Mount Skids?
Protect your rear low hanging shock mounts with RCI heavy duty rear shock mount skid plates
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)

Description

A Lexus GX460 IMS lift kit – Dobinsons offers this complete suspension system for the 2010 to 2023 Lexus GX460 4.6L V8, with various lift height and coil load options to suit whatever accessory weight you have added to your vehicle, and your desired lift height.  Contact Dobinsons directly if you have questions before ordering your Lexus GX460 lift kit.

Most customers when buying a Lexus GX460 IMS lift kit add 3″ of lift to the front and around 2″ to the rear, to help level out the vehicle from front to back.  You have your choice though of how you would like it to be.

A lift of 3″ in the front requires new Upper Control Arms for proper alignment and good ride quality.  These are sold separately.

dobinsons IMS specifications specs sheet

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 micro-polished, hard chromed and heat treated 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 and a race style 3-stage sealing system offer the lowest levels of friction whilst maintaining durability and longevity. 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 offroad 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 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.
Lifting the rear of the vehicle more than 2″ with KDSS, KDSS Rear Spacer Kit from Treaty Oak Offroad will need to be added to level out the sway bars front and rear and also provide additional wheel travel without the KDSS system limiting the suspension travel.  This spacer kit bolts between the original sway bar mounts, 1 on the front and 2 on the rear.  Some trimming of some skid plates up front may be required if they don’t allow enough clearance for the sway bar at full droop with the Treaty Oak Spacer kit installed.
