Whats the deal wit the trailing arms? Why do people extend them?
Do they extend the upper ones, lowers ones or both?
and why do some people instead of welding the power balls to the rear axle they weld them to the arms?
Extending front uppers = taking the stress of the balljoint when locking up/hopping.
Extending rear uppers = making the pinion angle better when locking up so the driveshaft don't bind up.
Powerballs on trailing arms = Impalas.
Powerballs on rear axle = G-Bodys / Caddys.
If you extend your rear uppers, you'll need to get a slip yoke driveshaft and a carrier bearing, just shortening the driveshaft is not clean, cuz it won't allow the car to sit real low safely, there's a good chance that your driveshaft will fall out the tranny when doing so. I run a slip shaft on anything juiced.
