Understanding the Gen 4 Dual Mass conversion
Posted: Mon Nov 27, 2017 5:10 pm
Subaru clutches are fairly new to me so am hoping to learn more about them
The thrust bearing has gone (chirping) so my Liberty's clutch is getting replaced. Mechanic was unsure if I have a Dual Mass or Single mass and has quoted for both situations. He explained that a conversion is a common practice for these models and looking through the forums and online, it appears there is virtually no difference in performance.
Has anyone who has had the conversion got any thoughts they'd like to share? If I have a dual mass I will be going ahead with the conversion as I want to keep the car for a while and past the next clutch change.
Below are the quotes, they sound fairly reasonable to me. He said it may be +$100 for machining, fluids etc
Option 1 - Dual mass to single mass conversion
- 5hrs = $550
- ACS Single mass clutch conversion kit $817
- Total: $1367
Option 2 - Single mass Flat*
- 5hrs = $550
- ACS clutch flat kit $363
- Total: $913
Option 3 - Single mass w step*
- 5hrs = $550
- ACS clutch step kit $586
- Total: $1136
*apparently there are two types of single mass flywheels, one thats completely flat and one that has a step.
My exact model is the standard 2.5L 2004 Liberty Wagon 5sp
