Product Description

Estimated lead time is 1-2 weeks.

Sky's new Chevy SAS ( Solid Axle Swap ) kit for installing 99-04 Ford Dana 50-60 solid axles. 

Kit will fit newer Chevy trucks, 98-up with a inner frame rail at shackle mount point dimension of 38.5 inch

Super Duty Ford Axle spring perch width of 37.5". 

Kit is designed around 47" Chevy 73-87 front leaf springs with a width at the bushing of 3.625. We have had some customers who have successfully fit 99-04 Super duty springs by moving the SAS hangers forward and aft on the frame. 

Kit is weld on, will require drilling the frame for the tube needed going through to hang shackles. This will require basic geometry skills to square the hanger to the frame and shackles. 

Kit will add 6" of lift to the springs use. A stock spring will give you 6" of lift, and so on.

Ford super duty axle will require either swapping the rear 10.5 Sterling axle in place of existing axle or changing bolt pattern on the front axle from metric pattern to 8x6.5.

Laser cut and CNC formed PnO steel, made in the USA!

 Front leaf hanger is 3/16th steel with a 3/16th skeleton brace, making it effectively 1/2" plate strength. Shackles are 3/8ths plate. Frame tube is 2.25x.250 wall DOM.  Kit uses a machined UHMW bushing and 3/4" bolt for the frame tube for long life, and less bushing sway.

This is a DIY kit, the simple way to install it is to bolt the kit, to the leaf springs, to the axle. Make sure you have them fairly square, then set axle under the truck. Determine where you want the tire to sit in the fender well and tack front hanger is place. Next set frame tubes directly under the frame with shackle vertical. The frame tube should be positioned through the frame at this vertical point, with 1"-1 1/2" of space from bottom of frame to the bottom of the tube. Tack tubes in place and set weight on the axle to double check position. Shackle should sit slightly rear ward, 15* and axle should be where it is desired. If change need made to position, now is the time.
