Parallel Leaf vs. 4-link
I am about to start the chassis build on a '37 Chevy coupe.
I have not used a 4- link suspension before and am needing the pros/cons between the parallel leaf and the 4-link.
This will be a street rod with a 383/700R4 combo.
Any info will help - Thanks

Do you mean a 4 link with coilovers??? IMO a triangulated 4 link with coilovers and polyurethen rod ends (not heim joints) is probably the best rear suspension on the market for a street rod. The triangulated 4 link by it's design does not require a Watt's Linkage or Panhard bar and doesn't have the tendancy to bind as does a parallel (even or uneven bar) 4 link. A leaf spring set up is the easiest suspension to set up, and also the least tuneable of any...Yesterday is history, tomorrow is a mystery, Live for Today!

This ride will be 90% cruising and 10% playing agianst friends in a little 1/4mile joust. This won't be a race car, but I would like the best performance that my shallow pockets can afford.
I was thinking the triangulated 4-link with coil-over shocks. I do not want to deal with pumps,lines and compressors that come with bags.
It sounds like the 4-link might be the way to go over leaf springs.....

Thank you all for the info, found a site that deals in polyurethen rod ends and am going to lean in that direction.

Besides working better It also "looks" better,compared to boring old leaf springs IMO.
Well I've sure gotten old too so don't worry about it! I've had two bypass surgeries, new knees, fought prostate, cancer and diabetes. I'm half blind, can't hear anything quieter than a jet engine,...
