{"product_id":"billet-aluminum-front-upper-control-arms-1","title":"Billet Aluminum Front Upper Control Arms","description":"By providing more precise control over the rear suspension geometry, these arms contribute to tighter, more predictable handling characteristics, benefiting both street and track use. The arms are manufactured from CNC milled 6061-T6 billet aluminum, utilizing Finite Element Analysis (FEA) in their design to ensure they surpass factory strength and durability standards.\n\nSPL Parts' exclusive Double Adjuster system is a key feature, comprising electroless nickel-plated 4130 Chromoly and 6061-T6 aluminum rotating clamps. This combination not only reduces weight but also effectively combats corrosion while allowing for quick and simple alignment adjustments. The use of blue anodized titanium hardware further minimizes unsprung weight without sacrificing strength, enhancing overall performance. Complementing the arms are FK Spherical Bearings and Rod Ends, which feature a Teflon liner. This design promotes quiet operation, reduces friction, allows for smooth articulation, and prevents bushing deflection under load. The liner is self-lubricating and self-cleaning, ensuring robust reliability across a wide operating temperature range of -65º to 325ºF.\n\nThese Rear Upper Arms are sold as a pair and are proudly Made in the USA. They are compatible with a range of Nissan models including the 1989-1994 240SX (S13), 1995-1998 240SX (S14), 1990-1996 300ZX (Z32), 1989-1994 Skyline (R32), 1994-1998 Skyline (R33), and 1999-2002 Skyline (R34).","brand":"SPL Parts","offers":[{"title":"Default Title","offer_id":52866387083576,"sku":"SPL RUCA Z32","price":494.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687687405.webp?v=1787906989","url":"https:\/\/store.motormia.co\/products\/billet-aluminum-front-upper-control-arms-1","provider":"MOTORMIA","version":"1.0","type":"link"}
