Adjustable strut rods - durability for street use

I ran the QA1 style adjustable strut rods on my Challenger for over 70k street miles using the car as my daily driver year round. Car saw dirt roads, mud, snow, etc. The heims were not booted and I didn’t do anything special to care for them. They’re the only part of that suspension to go the entire 70k miles, and there’s nothing wrong with them now. The same car ate the heims on the Hotchkis UCA’s I was running in 7k miles, and the second set has obvious wear after another 7k.

I also have a set of adjustable strut rods on my Duster, they were made by Dillenger chassis. They’ve got 30k + miles on them with no issues or visible wear. And no boots on them either. Both my Challenger and my Duster have 1.12” torsion bars. The Challenger ran 275/40/17’s up front for most of those miles, the Duster has 275/35/18’s. And 11.75” rotors on the Challenger, 13” rotors on the Duster. So lots of tire and braking loads on both those cars.

I wouldn’t run heims on the UCA’s of these cars again, but at the strut rods it’s not an issue at all. They’ll outlast any of the stock strut rod bushings hands down.
