what i want to know is will the spring rubbers effect the ride height along with making the spring stiffer. i put some drop spindles on my rod and would like to raise it up a smig. was going to try the spring rubbers and maybe those knuckle things that twist into the coil springs thanks
Well I've used the twist in knuckle things and they seemed to work fine. I would recommend maybe new springs or maybe those spring pads that go between the spring tower and the coil it self.
I have used the donut style rubbers on a mustang ll front end to adjust the ride height. i could see no appreciable difference in ride quality.
Had an old Volvo wagon that had saggy rear coils. Bought a couple of the NAscar style deals. They did a pretty good job and stayed in even running dirt roads in road rallys. I put two on the drivers side on onthe p*** side. Forget where I ofud them but they were 15 bucks a pair or so. I think they put a lot less stress on the coils than the twist in metal ones as the weight is spread out on a larger portion of the spring.
Yes, the twist in things look like **** but work. Rubber isolators are the next best thing to new/better springs. Just remember if you add 1/4in. worth of rubber, it will multiply to (about) 1/2in. at the wheel. Likewise if you cut 1" off coils it will likely drop the car about 2"... This applies to the front. Rear is usually directly over the rearend and what you add/take out is 1/1.
I've used the rubber donuts after "slightly miscalculating" the amount of drop I wanted in a couple of my cars. They work fine, add about 1/2-3/4 in to front end height. I don't like those twist in jobs, though, They can fall out, and they put stress on the springs in places they shouldn't. Probably cause the springs to fail prematurely.
Sounds like everyone's had mixed results. The one's I used popped out within a week and flew off into the ditch, they were the metal ones. Exactly how much is a "smig"? Perhaps just replacing your old worn out springs with new, quality replacement ones, that aren't 50 years old will put you back where you want to be? Just a thought...
on my truck 51 chebby,it sat a little to low, a-frames bottomed out,i found the rubbers and bought them to put in. then i found a set of the old twist in thingys laying around the shop and thought what the hey. put em in the day before i went to bowling green. shoot, raised it up jus a little,rode like a caddy. try the twist in jobs first.jmo
It's been years, but I tried all three: The metal twist-in risers are the quickest to install, but beware crossing rail-road tracks. The hard rubber donuts have a fairly deep channel that the spring fits into, so if the space between each coil is tight, you're going to need a rubber mallet and WD-40 to get the donut wrapped into a spring that is still in the car. If you remove the springs to put spacers/risers in, price either a new set of coils or get a pair of adjustable coil-over shocks like Bilstein. My 2¢
The twist in ones make great projectiles for oncoming traffic and the guy in the slow lane next to you...it's like having little unpredictable aluminum cannon balls! How cool is that?
here are some racing app. looks like diferent colors indicate different resistance rates, Speedway motors show them ad the plain block (road car ones) in their catalog.
agree with all on the twist in they go away always, the rubbers work if the lift isn't to high and the springs aren't ruined by the heat cutting them
