SPC Performance 86470 fixed-offset front upper control arms bring front camber and caster back into specification on GM 1500 trucks and SUVs. Lifting or lowering these vehicles loses caster, and the OE adjusters do not provide enough change on their own. The 86470 arms add 2 degrees of caster change, and the factory cams are then used to dial in the final alignment and restore drivability. Each arm uses fully forged construction, booted and greasable ball joints, and SPC xAxis sealed flex joints that pivot freely through droop. Sold in pairs.

FAQ
What do the 86470 control arms do?
They add 2 degrees of caster change so lifted or lowered GM 1500 trucks and SUVs can be brought back into alignment specification.
Why do I need more caster after a lift?
Lifting or lowering the truck changes suspension geometry and loses caster, and the OE adjusters alone often cannot recover it. The offset arms restore the needed range.
Are the ball joints serviceable?
Yes. The arms use booted and greasable ball joints and SPC xAxis sealed flex joints.
Are they sold individually or in pairs?
The 86470 arms are sold in pairs.
