The High Lift axles, the big rig axles, and the TLT-1 axles, share much of the same parts, including the gears. So yes, the pinion to spur gear ratios are matching. Meaning you can a TLT-1 axle or a High Lift axle for a powered steering axle on a big rig. The TLT-1 axle is slightly better looking, and a slightly more narrow as well, however both can be used. It's simply a matter of fitting a set of rims to the axles which have the poper offset to keep the wheels tucked inside the fenders. I believe most guys use the inner dual rims off the rear axles, to achieve the proper offset. The drive hexes match right up to the axles.
