Lifting post coil conversion.
Posted: Thu May 23, 2013 2:45 pm
So, my classic rangie has been converted from air suspension to coils long ago by the previous owner. The components look like they're Bilstein based on them being blue and yellow but I really don't know for sure. Not that it matters. I tried to order a 2 inch Terrafirma lift online and after some exchange with the sales rep VIA email, he says I need to buy heavy duty upper shock towers, rear dislocation cones and some heavy duty spring retainers. I feel stupid but I had NO idea that they would be different. I was under the assumption that a coil spring conversion kit would make your RRC mechanically the same as one of the earlier models that came stock with regular coils/shocks.
Now.. I ask.. is there any valid or serious reason the shock absorbers will not work in the stock mounting location (where they are currently) or is he just blowing smoke at me trying to sell more parts? They're mounted just outside the coil springs where as normally on a coil sprung Rover they would apparently be mounted inside the springs. So the mounting location is slightly different on a previously-air-sprung vehicle like mine but the action will be the same and I doubt the length of operation is really much different, either. So why do I have to buy these (likely expensive) new shock towers when I already have what appears to be a perfectly fine mounting location for them?
Also, why do I need rear dislocation cones for these new springs when I haven't needed them for my current springs? Aside from the physical length of the spring and probably spring rate, they will be the same. Mounted the same way, etc. If anything, wouldn't the longer springs be LESS likely to become dislocated than the current shorter, worn out ones? Which leads me to the spring retainers... Would I not already HAVE spring retainers? I off road mine pretty heavily and I'm sure if the springs weren't already being retained by something, they'd have fallen out long ago.
I'm a bit confused... Suspension work isn't my forte so perhaps one of you Rover veterans can explain this to me a little better than the representative could. I'm not sure English was his first language, the emails weren't well written. I want to make sure my suspension is put together properly for obvious reasons but I also don't want to be throwing away money when I don't need to. This truck was cheap and I'm trying to keep it that way, at least as cheap as a Rover can be.
Thanks much.
