Front 4” lowering coil springs

Anyone use western Chassis front 4” drop springs? My 1965 Chevy truck has a front 1975 c10 stock suspension. My truck was a c20 and I had originally put gmc Paul’s 3/6 kit on specifically made for c20 but I ended up putting a 71-72 c10 rear and I did keep the 6” springs in. I was told 63-72 springs won’t fit 73-87 . I rather go a lil lower in front 4 and keep my 6 rear is just a nice touch. Not really wanting drop spindles. Anyways performance online isn’t far from me and I could buy them there.

Re: Front 4” lowering coil springs

I have a 1972 C10 with 4" drop springs from the previous owner.

This is just my experience but I have a lot handling issues with the front end. It hits the bump stops and also gives a lot of bump steer issues.

I'm currently swapping the 4" springs for 2.5" drop spindles and 1.5" drop springs hoping to fix the front end issues.

Re: Front 4” lowering coil springs

never rode in 4" drop springs but from years of wrenching no way would i do this for many reasons .

split it up with drop spindles and coils . help each share the work load and make alignments much more easy to set .

Re: Front 4” lowering coil springs

I don’t know why they sell them that low at performance online. I don’t see any reviews on them. I will most likely just get some 3” lowering springs.

Re: Front 4” lowering coil springs

The springs probably arent the issue with the handling. Sounds like the front end needs to be rebuilt.
On one of my trucks I run 4" springs and 2.5" spindles and it rides fantastic. This is without a sway bar so far.

Re: Front 4” lowering coil springs

4 inch springs make getting a good alignment on the front hard to do and introduce a bunch of bump steer into the system. I would use a combination of springs and spindles. I like 2" or 2 1/2" spindles and what ever spring gets you to the 4 inches you are looking for. Then while you have it apart do the caster mod to the lower control arms (1/2" will get you all you need). You will be able to get 4 to 5 degrees of caster camber will be easy to set with out the extreme angle of the upper control arm that the 4 inch spring gives you and the tie rod angles will be pretty flat keeping the bump steer under control. The springs for the 73-87 are the same as 63 and up.

From what I was told 63-66 front springs will not fit in a 73-87 front suspension. But if you’re correct I do have 3” lowering springs when I had a c20 suspension But recently made my truck a c10 with front suspension out of a 73-87 Chevy c10. I had bought them from gmc Paul’s and they are supposedly made for c20. I just want to keep it simple.

Re: Front 4” lowering coil springs

Well They will fit from 63 to 87. The C20 springs may be a bit stiffer than the C10. On my 66 I have the 66 cross member, all the control arms, power steering, drag link, tie rods from a 78 and 73 to 87 drop spindles with 6 lug rotors. All this stuff will swap over including the complete cross member. If you go the the 60 to 66 FAQ section there is a lot of info as to what swaps over and how to do it. So all I'll tell you is i and many others have done it and they will go. Here is a link for front springs shows they fit 63 to 87.

Re: Front 4” lowering coil springs

Yea I don’t mind my ride being stiff. Before I did the 73-87 c10 front swap I removed my 8 lug 4.56 gears and installed 71-72 c10 5 lug 3.73....I re installed my c20 6” drop coils and it handled nicely. Yea I’ll give my front coils a try instead of spending more money.
