CT Race Worx Polaris RZR Pro R Toe Link Rods
The factory Pro R toe links have 2 major issues. The first issue is the adjuster assembly, which is made of up an eccentric bolt, constantly comes loose and throws the car out of alignment causing handling issues. The second issue is the material of the toe link is thin and it can't control the force that the tire is seeing through rough terrain, this is allowing the toe link to deflect inside the trailing arm which isn't allowing the rear suspension to hold a consistent toe. It creates unusual feedback and odd handling characteristics. So CT Race Worx set out to correct those issues.
CT Race Worx started the design process to address the alignment issue in the factory adjuster. At first CT Race Worx thought about doing a traditional link with a right hand thread on one side and a left hand thread on the other with jam nuts. It would have been simple but accessing the spindle side in the trailing arm would have been tough, especially with aftermarket trailing arms. The biggest fear was the jam nuts coming loose due to massive force that the link sees, if you can't get in to the jam nut to get proper torque you're going to have problems and if you drag the frame side over a rock and break the jam nut loose you're not better off than the factory design because the potential for a problem hasn't been eliminated. So CT Race Worx went a different route altogether. CT Race Worx created a clevis on the spindle side out of 1/4" Grade 50 steel with an internal gusset to eliminate deflection, CT Race Worx also threw the idea of the eccentric bolt and a slot in the clevis in the trash and went with a conventional round hole. On the frame side of the toe link CT Race Worx went with the proprietary single point adjuster that doesn't use any jam nuts. This adjuster is made up of a 3/4" LH JMX12T rod end, and 2 pieces that CT Race Worx machine here in house. The adjuster collar is made from a piece of 17-4 stainless steel that CT Race Worx heat treat for extra strength, this piece has a 1" OD right hand thread and also a 3/4" ID left hand thread and has multiple slots through the thread. The body that houses the adjuster has the 1" ID thread and has a slot through the body, to tighten it CT Race Worx have (2) 5/16" grade 9 bolts. To adjust the link, you loosen the (2) 5/16" bolts and use an 1-1/4" wrench to turn the adjuster collar. The adjuster collar and joint thread and unthread at the same rate making adjustments as easy as they could possibly be while giving 3/4" of total adjustment in overall length which is double what the factory allowed for. To tighten everything and secure it in place you torque the (2) 5/16" bolts to 25 ft lbs and you're done.
To address the deflection of the rod, the first thought was to go to a piece of 1.25" .125" 4130 chromoly. CT Race Worx built the first test set out of this but noticed how much deflection that diameter tubing had over the distance of the link. Since there are constraints to the overall design that don't allow us to increase the diameter of the tube, CT Race Worx could only increase the wall thickness. This toe link is made from 1.25" .1875" wall 4130 chromoly. CT Race Worx went this heavy for 2 reasons, to eliminate the deflection, but also to give piece of mind if the front portion of the toe link was to get smashed on a rock.
These parts have been ran and are proven at KOH. This item has the lifetime warranty.
Note
If you plan on ordering this part bare and are going to powder coat it, you can NOT let the threads on the inside of the adjuster assembly get sand blasted or powder coated. These parts get machined to an extremely tight tolerance and CT Race Worx test every piece after it is made, if that does happen, you won't get the adjuster back together and it likely will not tighten. If this happens CT Race Worx will NOT warranty the item if it does not function properly.
