370z SPL Front Adjustable Upper Control Arms

The time saved on the alignment rack can be spent in the drivers seat! The fully encapsulated spherical bearing that mounts to the upright provides superior strength and negates the worry of rod end bending commonly found in other designs. The wide adjustment range provides camber gain for racers wanting to maximize grip on the track and camber correction for lowered street vehicles needing optimal tire wear.

Using FEA (Finite Element Analysis) our CNC milled 6061 billet aluminum arms are designed to exceed factory strength and durability. Our exclusive hex cap double adjuster is comprised of electroless nickel plated 4130 chromoly along with 6061 aluminum clamps to reduce weight and prohibit corrosion while offering quick and easy adjustment. Ovesized USA made FK spherical bearings feature a teflon liner to provide quiet operation, lower friction, smoother articulation and eliminates bushing deflection under load. The liner is also self-lubricating and self-cleaning, offering robust reliability for street and track use.

Adjustment ranges:

On a 2009 Nismo test car we reached -4.8 degrees of camber at 5 degrees of caster. At -4 degrees of negative camber, we achieved 6.5 degrees of caster and at -3.5 degrees of camber we could get to 7.7 degrees of caster. Camber correction was measured at 0 degrees of camber.
