Other than OEM what’s a good cheaper strut/coil spring replacement to purchase for a sport suspension optioned 2004 LS430. Thank you.

 

The oem struts aren't too expensive, you have to get the sport springs though, which are a little more expensive. 48510-59355 Genuine Lexus ABSORBER Assembly, Shock (lexuspartsnow.com)
48131-50130 Genuine Lexus Spring, Coil, Front (lexuspartsnow.com)

 

KYB is your only option. Your best bet though is OEM and wait until Bell Lexus has a sale...

 

I went KYB struts on my ‘04 Sport and then Lesfojors rear springs ( All from Rock Auto). I then had to source front springs from Europe off EBay UK & EBay Germany. They were KYB. There are multiple spring manufacturers for the front since non-US cars got the Sports springs.
Cross reference the Lesfojors front part number and you should find them. Lesfojors isn’t selling the front springs anymore but it sure looked like the KYB & Lesfojors fronts were produced in the same factory.

I'm not a fan of Lexus springs due to the steel manufacturing. The ovate wire technology is so much better. It rides like a new ‘04 Sport and settled to the factory ride height. If you can find the front springs the Lesfojors rears are just over $100 for a pair on Rock. All four springs were just over $250 with shipping.

if you don’t want to search, get the KYB struts, Lesfojors rear springs and Lexus front springs. You’ll save a couple hundred dollars and unless you drive it another 140k or so the Lexus front springs won’t sag. All four of my original springs were sagged and struts alone can’t solve the ride when the springs were distorted . Good luck.

 

What happened to the Monroe Quick Struts? I thought that they would work well with the LS 430. They don't seem to be available anymore.

Rock Auto seems to be promoting a different strut and spring assembly.

 

I'm getting ready to replace my struts all around. So the sport strut should fit the 2006 non-sport model, right?

Anybody have the rear sport part number?

And yes, it should fit without any issue. Your ride height will be the same also, other than how your car has settled on the stock springs over the years.
