Sierra Spring over kit
Want more height and clearance without going to articulation robbing stiffer springs?
BBM's Spring over kit makes it happen.

Kit Contents
4 Spring perches - ready to weld on, relocating your springs to the top of the differential housing. Presicion cut, cad plated.
Complete cast high steer knuckle -quality cast replacement for the standard knuckle- has a new arm cast into it to mount the drag link( solves the old "link can't go through the spring pack" problem. )
Engineers we've dealt with prefer this setup to any other - bent steering arms aren't legal and bumpsteer everywhere. Attaching steering arms of wrecked vehicles to the caliper bolts is deadset dodgy. The high steer arms that just mount to the king pin bolts will rip the bolts out of the casting.
Drag Link - New drag link, heavy duty cad plated with new tie rod ends fitted. Adjustable both ends( so you can adjust it on the car)
Braided stainless steel brakelines -High quality ADR aproved stainless steel braided flexi lines. These are longer than standard to account for the extra height and flex your spring over conversion will provide.
Two tailshaft spacers - When the car goes up the tailshafts have to get longer. Tailshaft spacers provide an easy way to do this.
Complete Detailed Instructions - detailed , easy to follow instructions are provided with the kit.

You'll need basic handtools, axle stands, a decent jack (or forklift / engine lifter / hoist ) , brakefluid and someone with welding ability.
