Our all new front control arm design is a fixed 25mm extended and features a fully boxed arm made from only 4 welded components: the Spherical mount, two main beam halves and the lower ball joint nose section. By keeping components to a minimum and maximizing formed metal, we've reduced welding, increased strength and can deliver an extremely strong arm without the higher cost that comes from lot of welding.
All lot of manufacturers tout "TIG" welding as the only way to fabricate, but we find they usually have poor engineering with welds on every corner. You can use the "Best" process, but it doesn't compensate for bad designs. By moving the welds away from the high stress corners, we increase strength and dramatically increase the arms ability to take impacts with no worry if a corner weld splitting. Fabricating our way also significantly reduces heat in the material from extensive welding which causes it's own material stress and distortion. If you fold a cardboard box and tape the top and bottom shut right down the middle, it's quite a strong box, now cut the sides off and tape those back together. Which box do you want, the one with the formed sides or the one with taped sides?
We've used a replaceable Teflon lined spherical bearing for the chassis mounting point instead of a bushing. This is intended to keep deflection down and allow for good articulation of Caster. Typically when you pull arms forward to increase Caster, the inner rubber or Poly bushing will pinch on the corners and cause premature wear and possible failure. We've also used Stainless Steel spacers on the spherical to pass the main bolt through. This is not the place to use softer aluminum that can deform over time from the impacts front wheels can see. The stainless also ensures that any water and grime won't rust up the spacers around the bolt, making it hard to service.
The outer ball joint is a factory type unit. They have greater articulation angles than heims and are sealed and greased. If you've ever had a factory car go 100K+ miles on a stock ball joint, you'll understand the benefits of using them, not to mention they're readily available at any auto parts store.
The 25mm extended length has become a commonly known standard. While we had made arms with the ability for more width, we found that we always came back to 25mm and wished we just has simple solid arm with long life components, so that's what we've made.
The arms can use any tension rod that mounts up to the factory lower control arm mounting points, such as our single rod OEM style adjustable tension rods. You can get plenty of Caster adjustment while maintaining an ultra simple design that has extremely low component wear and failure rate.
The arms are offered in either powder coat Emerald Metallic or powder coat Chrome. We also have matching tension rods.
