ive have the few varations of allpro's marlins trail gears skys and OTT ( another great product) So far Sky is the only one that actually has the proper cone taper on the arms, Have decent lift and arent long making you have to push the steering box as far forward as most.
Just a little background i worked in a shop for close to 7 years where we damn near just did toyota SAS'... couldnt count the times ive done hysteer/crossover conversions... i could probably move a steering box blind folded >.>
