I got the tubular ones, and they are cheaper.

 

I've got the tubular with rod ends...they are awesome...You can't go wrong with either...Call Steve Spohn and talk to him about them...

The tubular's are great. I've seen the Spohn tubulars help push a 3,450# 30th SS convertible to 8.60@160+ MPH, with a 1.30 60-ft time. Definitely strong enough, and less weight then the box-section arms.

 

Aftermarket overbuilds everything. If tubular are strong enough for 1.3 60' times, then why make boxed ones? It's just so they can get more money for something you don't really need. Unless of course your car is speedygonzales and can pull off .8 60' times

 

Actually, it is probably the other way around. Aftermarket doesn't really have liability concerns since they sell their products as "off-road" parts with no guarantees implied. However OEM parts have to be very safe and last a fairly decent amount of time without problems. One great example of how under-engineered aftermarket parts can be is K-members. Some people have broken one under normal driving conditions.

As for the original question, go with tubular ones with rod/poly ends.

 

I know, but in this case with LCA's, if tubulars can sustain 1.3 60' times then why make an even stronger boxed one? Make it just so you can say the car can handle .5 60' times? Even though the car cannot even get close?

But I do understand that some aftermarket parts break easily.
