Man, I am going back and forth on which to get. Adjstble upper or solid uppers. I called UPR they said the pinion angle on the solids are -3 to -4*. I always thought that good pinion angle is 4 to 6*. Most people Ive talked to says go solid. Would going with the -3 to-4 angle make that big a difference? I sold a bunch of stuff on ebay, so I am ready to buy.

I run solid upr control arms, but I never plan on going 9's so thats why I didnt buy adjustables

So the adjstables are mainly for super fast drag cars? I dont ever plan on running 9s either. I am leaning toward the solids. But I would hate to regret my descision.

Anyone else help me make my descisoin?

I haven't looked into the prices between the two but if the price is not much more I would get the adjustable ones in order to have that flexibility in the future.

Don't have to go 9's to have adjustables. The correct pinion angle will help your 60' times.

u/l solid kit $199.99. Solid lower129.99 adj upper $159.99. so about $90 higher going adj upper.

if it were me, I would go for the adjustability. better to have it, then not. It is easier to buy it one time instead of twice, and end up kicking yourself in the **** later on down the road. jmo

Get THESE. I know a few ppl running them and like them.

So is it true, perfect pinion angle is 4-6*? Is there a good spot on the rear end housing to put the angle finder gauge and get it dead on?
