Howdy,
Seeing clutch springs advertised in classified section brings a question to mind. What is the compression rate (lbs) in one inch?
Thank you

Re: Clutch springs
@ 2" should be 90#.
Any spring with less I pitch.
The new repops are 100-120#

Re: Clutch springs
Does the added pounds affect operation of transmission? Improve performance or hinder operation?

Re: Clutch springs
The new springs will lessen possible slippage in direct drive.

Re: Clutch springs
Improves lock up. Less clutch slippage, which is adjustable to a point. @ diminished tension slippage may not be adjustable by increasing the tension with the 3 finger screws.
Real critical with TH400 clutches. Any slip wears the disks quickly. Eventually wearing away so much of the disks you have to replace them.

Re: Clutch springs
Is there a clutch spring rated more than the 110lbs suitable for use in a racing T engine? Or is it sufficient to use the 110 pound spring?

Re: Clutch springs
Racing spring? Not aware. Got info on them. Details?
The 110#(advertised) is the way to go for stock or th400 disks. (plenty)
I have the same spring with th400's behind a RAJO. Locks well enough to burn a little rubber In a full weight touring.

Re: Clutch springs
I always use the new ones in transmissions builds, especially if the customer requests a turbo or other modern lining clutch. They are not that expensive and good insurance.
