There are two different kinds of coilovers that we offer; partially threaded coilovers and fully threaded coilovers. Read on to learn how to adjust each below.
PARTIALLY THREADED COILOVERS
Partially threaded coilovers raise and lower the car by raising or lowering the height of the spring on the coilovers. With partially threaded coilovers like the one shown, to raise the car, you will turn the collars up the shock body and to lower you will turn the collars down the shock body.
To adjust the coilovers, first, unlock collar B by taking your adjustment wrench and turn it clock-wise. Once loose, spin collar B by hand down the length of the coilover. You will then use the adjustment wrench to turn collar A clockwise to lower and counter-clockwise to raise the car. Once you have the perches adjusted to where you want it, spin collar B back up against collar A and use both provided adjustment wrenches to lock the collars against each other. To lock, turn collar B counter-clockwise and collar A clockwise.
FULLY THREADED COILOVERS
Fully threaded coilovers have independent ride height adjustment and spring pre-load adjustment. To adjust the ride height of a fully threaded kit, unlock collar C by using the supplied adjustment wrench by turning the wrench counter-clockwise. Once collar C is loose, spin the lower spindle mount up or down the length of the coilover. To raise the car, you will lengthen the coilover, to lower the car; you will shorten the length of the coilover.
You can also adjust the ride height without having to unbolt the lower spindle mount by turning collar A or B but make sure that before doing so, that collars A and B are tightened against each other. Once collar C is loose, you will turn collar B counter-clockwise to raise the car or you will turn collar A clockwise to lower the car. Once the ride height is right where you want it, you will then tighten collar C against the lower spindle mount.
HOW TO ADJUST CAMBER
For coilovers that offer camber adjustment, you will loosen the four allen head bolts on the top of the coilover then adjust the coilover inwards or outwards. To make the camber more negative, you will adjust the coilover inwards towards the inside of the engine bay. To make the camber more positive, you will move the coilover towards the outside of the vehicle. Keep in mind, the more negative or positive camber that you run may result in increased tire wear.
HOW TO ADJUST DAMPING
For our Primo coilovers, to adjust the damping to be softer, turn the adjusting knob counter clock-wise. To make the damping stiffer, turn the adjusting knob clock-wise.

Is there any way you can sell the coilover spanned wrench separately i lost mines when i purchase my raceland coilover and I’m wonder if there any way i can purchase a pair of the spanner wrench
For sure. Just give us a call and we can give you a price on a replacement set. Our number to call is 801.365.1440.
Can you use these to lift the car beyond stock height? I’m looking for about 35mm of lift, but don’t want to have an overly-compressed spring as a result. Would you recommend this?
For which vehicle?
How to adjust springs in order to have a smoother ride and not a stiff,bouncy ride?

2016 honda accord sport, I’m putting sound system in my car so I will have a food bit of weight in the trunk, I’m changing out my struts to coilovers cause factory struts are bad in front, now from stock hight in from I’m thinking of lowering .5 – 1 inch, now for the back end all the weight is going to squat it down ,,will I be able to raise the back a hair above what I set the front too, should I loosen or tighten on the ride pressure with all the wieght back there?
We don’t offer an option for that model, but with most coilovers, you would have that adjust-ability.
i find my struts are bottoming out over pot holes. i have 2017 honda civic lx-p. it also has way to much bounce over bumps in road. i set the ride at soft hoping to smooth out the ride, but it is still a bad ride. i have all corners set to 25.5 ride height. i wonder should i increase spring height and drop height or do you have an other suggestion.
There could be other issues going on with your suspension. Give us call and we’d be happy to run through some trouble shooting with you. Our number is 801.365.1440.

Hey I was wondering how you adjust the rear coilovers on a 2014 Scion tC
The rear is just inverse from the front so to lower the car, turn the collars counter clock-wise and to raise the car, clock-wise. Let us know if you have any other questions!
I have classic coilovers is there any way to dampen the Springs for a stiffer ride?
We’re sorry but the Classics do not offer adjustable damping so there isn’t a way to make it stiffer.
I’ve seen all of your videos and read everything i can find on your website. But the answer still eludes me. So the question is, how do i set the preload on a partially threaded coilover i got from Raceland? Or does that not apply to partially threaded coilovers?
Because the ride height is determined by the spring pre-load, there isn’t a specific preset.
Thanks for replying to Pao’s question. I was going to ask the same. Let’s see if I understand correctly. For partially threaded coil overs, there really isn’t a certain adjustment to set as a preload. Adjust the spring the spring to the spring to what ever height you want and send it?
I have installed the Ultimos on an 07 Civic Si Sedan, but have not taken the car off jack stands and test driven the car. I would like to make sure that I don’t have the springs too tight or too wound up for when remove the jack stands. Any recommendations?
You are correct, partially threaded coilovers do not have a required load because it is the pre-load that determines the ride height. You are safe in either direction, depending on where you want the ride height set to. Let us know if you have any other questions!
My two coil overs are stiff in the front even though my dampener is set to soft. How do i fix that
Give us a call when you have a moment and we’ll run through a couple things with you. Our number to call is 801.365.1440.
I have a question about my classic partially threaded coilovers for my 2015 civic si. I have the rear maxed about and it still has a decent bit of wheels gap. My fronts aren’t maxed and I’m almost tucking so it confuses me on why my rear isn’t atleast sitting with no wheels gap. I couldn’t differ if it’s because my car is FWD or because the my rear coilovers are a divorced setup. But I have messed with the preload from the strut so my main question is if I can make the rear lower by adjusting that?
We’re sorry for the trouble! Give us a call when you have a moment, and we’ll run through some trouble shooting with you. Our number to call is 801.365.1440.
Can you adjust the height on partially threaded coilovers while they’re already installed on the vehicle ?
Yeah. You can adjust them while on the vehicle, no issues.
I have the raceland primos on my 2010 wrx hatchback and set to as low as they can go on rears. They did not fiil in all the wheel gap on the right rear side of the car. will spring preload mess with ride hight if they are both not set perfectly? I just installled them yesterday. I know they take time to break in but everthing should be sitting even like the front.

I have a 2005 Subaru WRX and ordered a set of Primo coilovers. I am wondering how many inches of preload is recommended on them? Both front and rears.
We recommend a max of 5mm.
