Lesjofors HD rear coil springs? 700/900

Greetings,

Searching hasn't helped me much and I need new springs in the back of my 745. So...

Has anyone used the Lesjofors HD rear coil springs on their 700/900 car? If so, what do you think of them?

I ask because I would like to know if they are similar or equivalent to the iPD overload springs. Also if they hold up well, raise the rear a bit, etc.

Thanks for any info

JY 245 springs?

I was wondering the same thing with those lesjofors,as a alternative to the ipd?s.i didn?t realize 245 springs were an option.

iirc 13mm is OE for 245 rear, & 14mm is HD

I ordered & installed 14mm for a 245(Swedish car parts - Sweden ?) from FCP, a bit stiff but great for heavy loads

My 88 765 has had the Kilen heavy duty rear springs installed for at least 13 years. Kilen is a subsidiary of Lesjofors. My car is always loaded with parts and tools and the shocks have never bottomed out. KYB Gas-A-Just rear shocks installed at same time. My 88 765 originally had Nivomat rear shocks. It had the rear springs and shocks upgraded sometime just before I got the car.
