Oct 29 - We are getting pretty close on last inventory for this year for a few products, (2) Ford & GM Core kits done your way. We have just (2) 4 link kits left in HD only, and a handful of trackbar kits. Once these are gone there will be no further production until next year, so plan accordingly. We are taking some time here at the end of the year to work on the site, product development, and video editing. Thanks for stopping by!

Description:

These are adjustable upper control arms for the Chevy Express and GMC Savana Van 2500/3500/4500 series vans from 2003-current. Our control arms are a permanent solution with rebuildable poly bushings, easily serviceable bolt-in ball joints, and in-vehicle adjustability that will give the alignment guys a ton of room to get the camber/caster split perfect. 

Application & Design:

These adjustable arms were primarily designed for our hi-lift conversions which use a knuckle that sits about 3 degrees in from the regular van knuckle and adjustable ball joints simply do not hold up. 

They will work for conventional vans without issue, Quigley vans, or lifted 2WD vans in most cases. The slots in the van frame are only good for about a degree in either direction and with these arms, we can achieve several degrees in and out with the adjusters. 

We went through many iterations of this design and this one works the best. It has in-vehicle adjustability and uses standard prothane Energy Suspension bushings which are much quieter than Heims and hold up well. The ball joint is bolt-in and a super common unit available in many brands for Silverado pickups which have the same taper as the van knuckle. 

Fitment Designed for: 

Van Side - 2003-2024 Chevrolet Express / GMC Savana 2500/3500/4500 series vans 

Tools Required:

Installation can be done with hand tools once you've made it to the point of installation, a set of brake caliper piston spreaders is very helpful. 

Included:

Left & Right control arms, complete with pre-installed Kryptonite or OE GM Ball joints, Teflon-impregnated prothane poly bushings, and appropriate washers.

Construction Notes:

1/4" Wall DOM tubing, powder coat finish, welded inserts, fully assembled. 

Tips / Skill Level:

1-10 (10 being most difficult) Level 3
