Why the Bilstein B8 Upper Control Arms
Leveled or lifted half-ton trucks that need corrected caster and ball joint angle after a 6112 or 5100 ride height increase. The Bilstein B8 upper control arms for your 2019-2026 Chevy Silverado 1500 / GMC Sierra 1500 2WD/4WD are a pair of fabricated front upper control arms with corrected geometry for lifted ride heights. They restore caster and ball joint angle so the truck tracks straight and the upper ball joint is not living at the edge of its travel.

Questions
When do I need these?
Any time the front ride height goes up more than about 2 in on a coilover-style half-ton. Corrected geometry brings caster back into spec and keeps the ball joint from binding at full droop.
Do they work with other brands of lift?
Yes. They correct geometry for the lift height, not a specific shock, so they pair with Bilstein 5100 RHA, 6112 or another brand of leveling kit.
How long does installation take?
One to two hours for the pair, plus an alignment.
What is the warranty?
Limited lifetime warranty (Bilstein North America). Bilstein warranties are non-transferable and processed through the original place of purchase, so keep your Hannah Suspension order confirmation.
