I have tried Moog. Tries Proforged. Both are of the same casting and do not sit on the splines of the sector shaft like a standard bipod arm. This is unacceptable as it will throw off the handlebar alignment/truing and can lead to alignment issues and even worse steering issues, especially if you have oversized tires. This solved the problem. It's a bit thinner/less bulky than the Moog and Proforged which is why I bought them in the first place, but they hold up great.
