So a couple weeks back i ordered the ISIS adjustable arm package which includes RUCAS, rear toe rods, rear traction rods, and front tension rods. I just now got around to doing the install and thought i could do a write up, so here goes.
Tools needed:
3/4 and 1/2 drive ratchets
17mm wrench and socket
19mm socket
adjustable wrenches for the bolts on all the rods for adjustment purposes
large pair of pliers
hammer
pry bar
Install time about 4hrs give or take your experience and knowledge
here are the new arms
Here are the factory arms you will be replacing.
And the traction rod
Now on to the step by step on the passengers side since I completed the driver’s side first.
remove the 2 bolts that hold the toe rod in place you will need a 19mm socket and wrench for both bolts
compare the rods side by side and adjust the new rod so that all the mounting holes line up with the factory rods holes
install the new rod this is where you may need to use the pry bar to pull the spindle into place to insert the bolt. install the rear bolt first its much easier
now for the rear upper control arm (RUCA) this is a tad bit tricky as the rear bolt is a factory camber adjustment bolt and must be removed by turning the nut only, because of a keyway built into the bolt for the camber washer. simply remove the nut first and then the bolt
remove the nut and bolt up front using the 19mm socket and wrench and then the camber bolt in the rear using a 19mm socket and a 17mm wrench. make sure to turn only the nut so you dont mess up the keyway on the bolt
side by side comparison again use the same method on the RUCAS that you did on the toe.
Note:be sure to place the rear camber bolt in a similar position as you did on the driver side so that your camber will be similar until further adjustment
now for the Traction bar. This bar also has a camber/toe adjustment bolt in the rear as well,just treat it the same as you do the RUCA bolt and all else is the same.
remove the front bolt using the 19mm socket and wrench as you have so far and then remove the rear camber bolt using the 19mm socket and a 17mm wrench. remember to only turn the nut and then remove the bolt
line up the mounting holes as you have done before and install
Install complete
Now for the front tension rods this is by far the easiest part. You will only need a 17mm wrench and socket
This is the rod you will be removing it is bolted to the lower control arm and the power brace.
remove these 2 nuts using the 17mm socket
remove this bolt using the 17mm wrench and socket
side by side comparison, just line up the mounting holes and make sure to adjust both the new tension rods the same way, i had a little bit of difficulty with this because i did the passenger side one way and the driver another and ended up having to go back and redoing both of them after a test drive
reinstall by placing the studs in place first and the spherical bearing last you may have to pull the control arm towards you a lil to slide the bolt into place but its not to difficult
install of the tension arms is now complete
heres what it should look like when completed
After an install of this caliber i would highly recommend an alignment. you can pretty much “eyeball it” so that it is driveable with minimum fuss but an alignment is necessary. The overall install was quite simple and straightforward, the products are well made and of high quality for the price and i would def recommend them to anyone that is on a budget and is wanting as much adjustability from their suspension as possible. The welds are good and solid, the overall design is precise and the adjustability is very beneficial. This arm package is definately on par with all other arms on the market, ISIS has created an Outstanding product and i will def be purchasing more parts from Enjuku Racing which as of now is the Exclusive dealer of all ISIS products.
