SPL's Titanium Series of thrust arms allow you to adjust caster to maintain proper suspension geometry. Having versatility in your alignment specs is optimal in achieving the most precise alignment for your vehicle's purpose - giving you the best turn in response possible while also compensating for variances in left and right caster. SPL uses ultra low friction, smooth articulating FK spherical bearings to give your vehicle an extremely responsive steering feel compared to the stock soft rubber  bushings.

Manufactured using precision CNC'd & gun-drilled billet aluminum 2024 hex rods to reduce unsprung weight while retaining high strength and stiffness. SPL's 360 degree rotating clamp design gives you easy access to altering your alignment. 3-Piece FK Bearings: These rod ends are manufactured in Connecticut. JMX is a hardened rod end used to provide increased strength. These utilize a teflon liner that eliminates bushing deflection under load, while also offering quiet operation, low friction, and smooth articulation. The oliner has a high load carrying capacity and has heightened dynamic wear characteristics - supports operating temperatures between -65 to 325 degrees Fahrenheit.
