Cal Trac Traction Bar Kit

The combination of these components change the pushing point on the car by redirecting the turning action (spring wrap-up) of the rear axle through the #2 Force Transfer Link into the #1 Front Pivot. (See detailed image below). The Front Pivot Spring Stop resists this turning motion and also controls the bending of the leaf spring at it's thinnest section. The push into the Front Pivot helps the cars weight shift towards the rear of the car, because of new directed angle of force toward the front of the vehicle. (The 'Instant Center' moves further forward). This is where the system emulates a Four link system. The pinion angle is also maintained.

Would not work in my jeep
Color: Textured
This seems like a decent holder, however it is not universal as it would not fit in my jeep. Check to make sure you have the right kind of air vents for it. I could not get it to work for my vehicle as the vents are too wide.

Works great!
Color: Black, Color: Black
This is a very simple, lightweight phone mount. It works well, I’m surprised how securely it fits on the car vent. I’ve tried others and couldn’t get them to fit right. My phone slides into the top and fits nicely. It was easy to install.

No drilling required
Size: Large
I installed this on my 2021 4Runner with the adhesive provided and no drilling. It has been a few months and it’s still solid. I live in Hawaii and the temps in the car have reached over 100* F pretty consistently and the adhesive has held up very well. There are a lot of attachment points for whatever you want to use it for. I only wish they sold the magnetic mount that it comes with so everything can match up. I use it for my phone and baby monitor. I would purchase this again.

Love this ram mount kit
Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121, Size: Fit for Silverado 2020-2025 GMC Sierra 2019-2121
All i can say is wow. This is an amazing ram mount kit for my 22 Silverado custom. All the hardware is top notch. The metal is all powder coated black with a nice grey American flag. There are so places to be able to mount addition arms. The phone holder it comes with is solid aluminum with a nice tight spring. I rate this 10/10 and for the price you can not beat it or find another better. I didn’t use the adhesive on the bottom so i can’t speak on that but i can only imagine it is really good as well. Hands down is just as good as the super expensive bulletpoint mount you see advertised. Don’t hesitate to buy.
