What Does Rack Correction System Mean?

ReadyLIFT RCS Explained

If you have ever wondered what we mean when we mention that our big lift kits include RCS, well we are here to give you the 411 on what it is all about and how your truck will greatly benefit from it. RCS stands for Rack Correction System. In essence we have “corrected” the steering rack and tie rod angles so they maintain the factory geometry in a drop bracket lift kit situation. I’m sure you are wondering, “how does this benefit me or my lift kit?” It actually helps in a variety of ways.

Traditional drop bracket style lift kits do not drop the rack and pinion and requires a new knuckle to be made to accommodate the extended distance between the upper pivot point (upper control arm) and the lower pivot point (lower control arm). Additionally, by not dropping the rack and pinion and changing the outer pivot points, the stock tie rods are too long and must be cut or shortened. And then after all of this, the new larger knuckle design required to accommodate the non-dropped tie rod has the tie rod pivot mount much farther outside of the factory wheel circumference. That means that you can only run aftermarket 20″ wheels or larger with this kind of set up and the front track width is increased. This results in the front wheels sticking out farther in front compared to the rear.

By now you may be thinking this seems very complex. Well to be honest it really is. Dropping the rack and pinion steering assembly is very important if you want to retain your factory turning radius, retain OEM alignment specifications, retain your factory front track width and finally, if you ever want to bolt your factory wheels or spare wheel and tire onto your truck.

At ReadyLIFT we feel that all of the above are critically important for many lifted truck owners. With ReadyLIFT RCS you can feel comfortable that in the event that you need to use your factory wheel or spare, you can. If you don’t want to run aftermarket fender flares to cover the wider front track width of a non-RCS style suspension, you don’t have to. If for some reason you have to replace a tie rod assembly, the technician doing the work will not know that your original tie rods were cut. So you will not be able to align the truck unless the replacement tie rods are cut exactly how your original ones were.

I know this sounds like a lot to digest but RCS really is a difference maker! When you lift your new truck you would really like for it to handle like it did stock as well as be able to make a u-turn without having to make a three-point turn. For most ReadyLIFT customers this one aspect of RCS has been a huge benefit for them. And there is something to be said for having your truck look “right” by having the front and rear track width be the same. If you are a stickler for these kind of details, then the ReadyLIFT Rack Correction System was designed for YOU.
