Leaf spring traction bars

Definitely use the leaf clamps first, start with one on each side in front of the wheels. Add as necessary. If you buy the Mr.Gasket set, make sure you have a grinding wheel to shorten them - they indeed hit the frame rail upon launch. Also, the Mr.Gasket set has bolts with too long of a shoulder, and therefore you will need to purchase shorter bolts or at least bolts without a shoulder. With this much work it may be better to follow Rob's advice and make a set.

They definitely work, I raised my launch RPM from a 1000rpm idle launch to approx. 2000prm launch with no wheel hop and minimal tire spin.

During the SS&DI magazine test back in 1969, Ed Hedrick used 3 clamps per side on the Yenko Camaro demo car. Car got into the 11's.

BTW, Ed is an engineer, who helped Grumpy with much of his chassis/driveline problems. At the SCR Ed spoke about the time Grump watched as Ed launched Grump's car several times "inside" the shop.

Thanks. I will make some clamps this weekend. They look almost too easy to make.

A little off the main topic, but I also found it interesting when Ed was talking about the natural frequency (vibration) of the driveshaft and what engine rpm it happens at...

Thanks Tony. Yours look almost identical to what I made. You have a PM...Tony
