240 Coilovers with Koni Sport Dampers
This product gives a package option for coilovers to ease ordering.
These come available in stock length housing or shortened housings.
This package includes:
- Koni sport dampers front and rear
- Front coilovers and rear adjustable spring perches
- Eibach XT springs in the front and Eibach 5" OD springs in the back
- Koni front bump stops
- Refundable Coilover Core ($300)
This package is ideal for people who are looking for a budget Coilover option that is a complete bolt-on and ready to install.
These are a good option for daily drivers at any ride height.
For the Front:
We modify and refurbish Volvo strut housings by removing the factory stamped spring perch, shorten and thread the housing (if required), welding on a stop ring, sandblasting the assembly, and then powder coating.
The new setup receives all American-made Coilover hardware with American-made materials.
We use American-Made Eibach XT spec springs in the front, these springs are a premium product that uses a barrel geometry to improve stability, load capacity, and travel. It also provides the necessary clearance to keep the springs from rubbing the Coilover hardware, a straight geometry spring can often rub and will over time cause noise and will wear the threads off of the adjusters.
There are two front struts available in this package. Both have similar valving and stroke but are different lengths. This allows us to maintain good ride quality at whatever ride height is desired. The valving is well matched to medium stiffness long travel springs. If a very firm ride is desired, we recommend running our race dampers.
If the car will be lowered 2 inches or more, we recommend adding the shortened housing service, this allows for good ride quality at low ride heights.
For the rear:
We offer a variety of dampers, 1 sport option, and 2 "Race" options.
The standard rear shock is a 240 Koni Sport Yellow.
These dampers have a long travel, and if you are running shortened housings in the front, it is likely that your rear springs will become unseated the car is in the air. Our spring perches have built-in holes to secure the spring to the perch which keeps the spring seated in this occurrence.
We recommend installing the adjustable spring perch on the upper frame rail and moving the stock upper spring perch to the trailing arm. The geometry of the rear suspension will allow the spring to naturally re-align itself if the spring is attached to the upper spring perch. If you anchor the spring to the trailing arm, it will not seat itself as smoothly.
This can be avoided by opting for our rear race shock upgrade. The race dampers feature a shorter droop length to keep the springs engaged at lower ride heights.
Rear Shock Upgrade: What is it and why would I want it?
The standard rear 240 Koni sport is a very stiff damper and is intended to control the car with very soft springs. These can lead to an overly harsh ride when increasing the stiffness of the springs. The "Race" dampers offer lower compression and rebound valving than the standard Koni sports, if you balance this with an increase in spring rate, you get a more stable and more comfortable ride. The Race dampers are also built on a larger damper body, these have bigger valving and can operate at a low gas pressure which helps with ride quality.
The Race Shocks are available in various lengths, if you plan on lowering the car significantly we can supply a shorter stroke damper to keep a shorter spring from becoming unseated then the dampers are at full extension.
We often get asked what the "Core" is, hopefully, this will help clarify. In this kit we are modifying a factory spindle strut housing assembly. In order to help you save money on these parts we offer the option for you to supply us with these parts instead of just forcing everyone to buy a set of strut housings from us.
We only use the later 1982+ Cores for strut tubes. Those cores have thicker and stronger tubes that are more resistant to bending. They also have an improved spindle design which has stronger wheel bearings. Early spindles are available upon request but are not recommended.
The current cost of spindle cores is $300. If you wish to avoid paying for a set of spindle cores you can supply a set of cores for us to modify for you before you place your order and avoid any core charge.
This product includes a $300 core charge which is already included in the price listed above. If you return your original strut cores at a later date and we will refund your core charge. If you are sending us a set of cores back they must be in good serviceable condition. Good serviceable condition is defined as the following:
- no significant rust or corrosion,
- no damage or excessive wear to the bearing surfaces,
- is generally straight.
- Not cut or modified including the brake line brackets
If you have a set that is questionable please email us and we can confirm if they will be accepted or not.
You can supply a set of cores for us to modify for you and we will reduce the price of the Front or Front & Rear Coilovers by $300.
This is what the core looks like (ABS 240 Unit Pictured). When sending us the core please remove the springs, wheel hubs, backing plates, brake components, and strut inserts. It is also a good idea to tape or protect the wheel bearing area as it is easily damaged in transit.
