Why convert your truck to the Offroad Design Rear Coilover System?
Best ride possible
With a leaf spring system your axle moves forward, back, and side to side so driving feel is very mushy. With links your axle as a designated path so everything feels more precise. This will make your truck perform more like a brand new one.
No more spring wrap! With the 4 link rear you will no longer get the wheel hop that comes with springs. All your horsepowers will be getting to the ground.
High quality shocks come standard
When getting into the coilover kit you instantly get a large body remote reservoir shock more than capable of handling anything you throw at it!
Everything in this kit is comprised of very high quality materials that will lower your maintenance. No more replacing spring bushings or checking U bolts! Also having a softer suspension will be easier on the rest of the components of your truck.
With our coilover kits you can do anything from nice on road daily driver to hardcore go fast dunes and everything in-between (rockcrawler, camping rig, overland, tow rig, and weekend cruiser). Weight is not a problem either! Can be anything from all aluminum LS to heavy diesel motored trucks with huge bumpers, the coilover kit will add performance with ease! For tow rigs we recommend using air bags with the daystar cups. That way you have towing capacity when needed and flex for the fun days.
Can I install the coilover kit myself?
Since there are varying skill levels that is a hard one to answer. This kit does require a lot of welding, cutting, and also free form fab. To see if you are up to the task check out our coilover resources page under the tech center
Besides the coilover kit what other items are needed?
You may need other items like longer brake lines, drive shafts, and a lift or links for the Front to match the Rear if you are starting with a stock (not lifted) truck
What vehicles does this kit work with?
1969-1991 Chevy trucks/SUVs
Our kit will work will the 1969-1972 era GM trucks and SUV's as well as the 1973-1991 squarebody GM trucks and SUV's. It will not work with the later GMT400 or GMT800 IFS trucks.
Why 4 link?
What makes Triangulated 4 link the best option
You will get the most articulation/ride without taking up as much space.
The hoops are used when trying to get the most travel possible. The hoops will go through the bed floor and allow the use of a 16" travel shock
Under Bed Shock Mount
This bracket is used to keep the shocks under the bed floor. Use a 8", 10", or at most a 12" travel shock (may need to fabricate lower axle side shock tabs)
What axles does this truss work with?
We have (2) truss options for this kit, the 14 bolt full float and everything else. The other truss is designed for 3" axle tubes so it may need to be modified for your axle since it is a universal truss.
What travel shock should I get?
Shock travel options
The lowest travel shock we can do with this kit is a 8" and the longest travel shock that will work is a 14"
Full Flex rock crawling
16" Travel for through the bed, 12" if under bed
Go fast dunes
16" Travel for through the bed, 12" if under bed
8"-10" Travel and use under bed brackets
8"-10" and use under bed brackets
Mixed use on/off road
16" Travel for through the bed, 10"-12" if under bed
Using tall truck bracket (9"+ lift)
8"-10" Travel and under bed
Spring rates and valving
We use the information you provide with use/info on the vehicle to spec out spring rates and valving for your build if your purchase the shocks through us. If you purchase shocks though another source sorry but we WILL NOT spec valving or spring rates.
King Shock Info
Our standard Fox Performance series coilover is a 2.5" body, remote reservoir, with black/silver anodizing. Fox is an extremely high quality shock company with products used in OEM applications. They do have some add on options like the Dual speed compression adjuster "DSC" (used for changing High and low speed compression).
Fox external bypass shock
The external bypass shocks add even more on the fly tuning. These are great for when you are wanting to use your truck as hard as possible! So if you plan to see air under your tires all the time add some external bypasses!
Fox Bump Stops
The bump stops are used to slow down the bottoming out of the suspension. If you plan on hitting full bump a lot add some of these bump stop. We typically run 2.5x2.5 with most of our rigs
Does this kit require cutting in the engine bay
With this kit you will need to cut your inner fender wells for the shocks/shock mounts to fit. If you have a stock A/C box it can be very difficult fitting shocks/shock hoops around it, we suggest going to an aftermarket one that moves the components under the dash for ease of install.
Can I move my axle forward from stock
You can to a point
Typically you can move your axle forward .75" from stock, some have made 1" forward work. Anything past that you will need to move your steering gearbox which we do have a kit for.
A sway bar can help tame down body roll with your new soft suspension. We do carry coilover sway bar kits. These kits are a heavier bar great for on road. When you want to get your full travel off road we recommend disconnecting it.
