2013 Ranger Trailer single axle trailing arm bolt torque

[ram41569]

Single axle has a 6 lug rotor which has a larger 7/8" pinch bolt. I bought a set of grade 8 bolts. What would be the torque rating to tighten these bolts. I know the smaller grade 8 bolts on a tadam trailer is 150lbs so what would the larger 7/8" bolt be torqued to. Thanks

Here is one chart, I assume you are using stainless bolt.

Ok so I see where on a 5/8 bolt tandem trailer on boltdepots chart is at 150ft lbs but with a single axle 7/8 bolt there showing 450ft lbs. That's doesn't sound correct. That would be too much torque on the aluminum trailing arm?

You do realize the chart is in reference to bolt diameter nut nut size or wrench size.! A 7/8” bolt is a beast.!

The 5.2k -7k torsion arm uses a 7/8” diameter bolt not the 5/8” used on the 3.7k torsion arms. I would hate to try and torque that bolt.
