SPL Front Upper Control Arms (370Z / G37)

Brand: SPL

Product Description

SPL front upper arms are designed with dual chassis mount adjusters providing camber and caster adjustment while remaining fully attached to the car.  The revolutionary slotted arm design does away with the need for bulky and hard to reach jam nuts.  Simply turn the hex cap double adjusters to set the arms to their desired length and then lock your alignment settings in place with an allen wrench. 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) SPL 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.

SPL Front Camber Arms Features:

  • Lightweight aluminum, stainless steel, and chromoly construction
  • Electroless nickel plated 4130 hybrid adjuster for quick adjustment
  • Computer Aided Design with the aid of Finite Element Analysis
  • Low friction 3/4" 3-piece Teflon lined FK rod ends and sphericals
  • Offset chassis spacers to maximize caster adjustment
  • Black anodizing for a durable finish
  • Made in the USA

Adjustment ranges:  On a 2009 Nismo test car SPL 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.

This thing is built like a tank and now my front end feels rock solid also, it took me about 2 hours to put both sides then took it to get aligned for negative 2 and plus 7 caster it feels completely different to drive it just wants to be thrown into corners, it should have come from the factory with this
