Default 2013 GS350 restoring to original shocks

I love my 2013 Lexus but.... when I bought it, it had been lowered by the previous owner. I want to restore it to it's original height - almost 58 after all - and don't know how I would do this. My mechanic said it would be very costly and hard to find shocks?struts? combo for this model. Is this true? whats entailed in restoring the original shocks and what do I have to buy? Any recommended parts dealers online or in Toronto aside from wreckers maybe? I might have to go to wreckers after all. Not sure. Help please. thanks

Used springs are out there and cheap, new shocks/struts are cheap (around 100 a corner) new from rockauto. Buy the KYB ones, they are the OEM brand.

AWD or RWD?

I have a set of stock 2013 AWD springs that I will happily send you for cost of shipping plus a little extra.

Do you know if the shocks are stock? I only changed my springs. That may have been done for yours as well.

good question - is there a way to tell if its both and how aside from hoisting it up to see? It might have only been springs - not sure.

If the stock springs were riding at a lowered height for years, there's a good chance they'll need replacing. If they're even at stock height after all those years, it's a good idea to replace them too. The labor and cost for alignment is the same whether you reinstall new shocks or use your old ones. All around best to just replace them. People underestimate how relevant to safety/traction dampers are. If you hit a bump mid-corner and your shocks don't rebound/react like they should, there goes your loss of control and possibly your life if you hit a tree or something around a bend. Definitely replace!!! The best tires in the world won't mean a thing if your dampers are performing sub-par or not performing at all.

so replace shocks/springs/ and ? Good places to buy these online in Toronto and save some $ at least. My mechanic said very expensive and hard to find. True?

I have the 2013 springs, and Newly purchased AVS Struts on my 2013 GS350. I want to sell them to get lowering springs and the 2017-2020 Stock Struts. The new Struts I have only have 850 Documented miles, and my car only has 41k miles. I dont know if the springs and struts are the same on the RWD as the AWD?

Any idea how I find out if they are just the springs? I wouldn't mind taking those springs from you though. LMK

If you are trying to restore the factory ride height and quality, I highly recommend you purchase new OEM springs and shocks (you may want to contact your local Lexus dealer to determine the correct parts per your VIN). The lowering springs will likely have increased the wear on your shock absorbers, so even if you do put factory height shocks back on the car, the handling and ride quality may still be degraded.

Unfortunately, RWD and AWD use the same rear roll bars, but different front roll bars as well as different springs and shock absorbers.

The shock absorbers below are for Luxury and F Sport, and all for 200t/300/350/450h drivelines.

That's an awesome resource. Why did Lexus revise the springs in 2019?

A number of people thought the 2016-18 springs were too soft, so that could be why they made 2019-20 springs firmer, but still softer than the springs used in the original 2013-15's; an intermediate balance between the two.

Below is a photo of the 2015 vs the 2019-20 pair of OEM front coils for the GS350.
Wearing the 2019-20 coil springs, the GS does NOT ride any higher off the ground than the 2015 coil springs - despite the longer uncompressed coil axial height below.





Below is the 2013 vs the 2015 OEM front coils.
The right is the 2013-15 OEM rear coil.
The coil axial height of the 2013 and 2015 OEM front coils are about the same.
The 2015 front coil has greater linear coil length [with a greater number of turns/axial height], with the coil being flattened at one end; the flattened end is actually the upper end, such that these coils have been photographed upside down.

Although the spring design and part number is different, I could hardly tell the difference between the 2013 vs the 2015 coil springs.
However the 2019-20 coils are definitely softer and better riding, while the 2016-18 coils have the nicest ride.
