React Trailing Arm Crossmember - 63-72 C10

This trailing arm crossmember is a direct replacement for all 63-72 C10's with factory trailing arm suspension. Using 3/16" steel, it's made in the USA and provides a more aesthetically pleasing crossmember, while adding adjustability. The React Suspension crossmember can be positioned back 1", and when paired with React's trailing arms, it offers even more adjustability. 

Has provision for carrier bearing mount, but will have to be made by customer for each application. Mounts provided for easy adaptability. The crossmember installs as shown in the photo; the large "dip" will be to the top.

This crossmember includes adjustable trailing arm pivot mounts that allow you to fine tune your pinion angle. The React Suspension crossmember will accept stock  or aftermarket trailing arms such as React P/N 6772-001. 

Bracket can be added to allow an inline carrier bearing to be utilized, when you have  2-piece drive shaft. 

Will allow 3" exhaust to pass through.

    Super fast shipping and great price!

    Bought these during the Black Friday deals and got my React pieces the same week! They look great and the price was too good to pass. Can't wait to throw them on my 1967 C10!

    Well designed crossmember

    I was having issues with drive shaft rubbing and pinion angle until I came across this crossmember. Everything you need all in one unit is engineered to perfection. Fitment was on point. Kudos to a Great product!
