BMS OFF ROAD announces a new product to our growing line-up of upper control arm kits. We have just developed and tested a new kit for the HD 2wd and 4wd Chevy and GMC trucks. This kit offers a replacement upper arm that features a 1” outer uniball with a heat treated 4340 pin. The uniball cup angle has been modified from stock in order to allow for more downward movement. This is important when cranking the torsions or adding torsion keys.

Along with the stronger outer pivot, the plate construction features interlocking plates that can be found on our other full-race style components and chassis. When you put all of these features together, you should expect increased offroad reliability and performance. The KING bolt-in shock provides a smoother ride, and compliments the arm with 29% more travel.

We are also offering the Steering Upgrade kits for $550 with FREE shipping!



Here is the link to the GB for these.

We have added another compliment to the boxed upper arms, a 7075 Aluminum heim steering kit. This kit utilizes 7/8” and 3/4" heims on each end with a 17-4 stainless steel clevis and 4340 heat treated pin.

thanks,
Jason

Does this make it like the cognito arms fixes the angle so your not ridding on bump stop.

The forth pic doesn't look good not enuff clearnce :imo
There is more then enough. That heim/ spacer combo articulates more then the stock tie rod, so where the stock unit maxes out the heim will not. using that size heim and bolt there no no possible way to increase the amount of articulation without the kit getting very expensive. This is the best way to fix the issue of the stock units.

good stuff from BMS.

Jason....little off topic, but on the 1500 arms you made for Sam Carroll and a few others the arm was angled to correct bumpstop clearance when used with a strut spacer....what are the wheel requirements for this arm...like maximum backspace etc?
