Spring Rate recommended
Posted: Wed, 23 Feb 2022 6:48 +0000
Hey guys!
I have a 2018 Hilux SR 2.8 (don't know exactly the complete version). And I just bought an Ironman Foam Cell Suspension Kit.
I use my truck mostly on paved roads in the city, but at least once in a month I go on some bad dirt roads in the mountains (here in central Chile, roads are pretty rough, rocky and with lots of this little "ripples"). Also I have no front load, and just some ocasional small loads in the backs like baggage, climbing and camping stuff, etc. No heavy constant load
The thing is I feel the new suspencion stiffer than I thought, even in regular paved roads. I noticed they sold me with the kit the TOY065A coil spring, which is 18mm diameter and it has a spring rate of 720 lb/in. Cheking on internet I think is too much for my use.
I know letter A in Ironman springs means the lighter or more confort version, but TOY055 models also suits Hilux, and the TOY055B is 17 mm and 669 lb/in, and TOY055A 16.5mm and 606 lb/in
Which one do you recommend? is it 720 lb/in too much?
Thanks!
