High Lifter Apexx Front Forward Upper & Lower Control Arms Polaris RZR Pro XP This set of heavy-duty control arms offers superior reinforcement compared to OEM counterparts. Constructed with 1.5 DOM and .188 wall tubing, it showcases a growth of 50 in size and an upsurge of 70 in steel density for enhanced resilience and sturdiness. The lower arms also host an adjustability element in the bushing collars aimed at averting premature wear, which often results from implementing lift kits, portals, or larger tires. With the bushing collars set to factory position, they provide 3/8 of adjustability camber in both directions. Heat-treated and plated adjustable bushing collars convey confidence in the strength imbued into the vehicle. The kit arrives pre-adjusted to the factory position and fits best using factory bushings and caps for installation. The strategic incorporation of double and triple bends into the design of the lower control arm elevates ground clearance by an extra 1.75. These unique bends retain the factory geometry, minimizing wear on components like axles and tie rods. These forward arms accommodate larger tires (up to 34.5 depending on application) in the absence of a suspension lift. An alteration in the location of the sway bar tab on the upper control arm reduces extreme angles on the sway bar links and mitigates wear. Features reinforced ball joint brackets, which extend the ball joint mounting area by over 130, aiding the prevention of bracket breakdown or egging. Features: Optional pre-installed ball joints Adjustable heat-treated collars for camber adjustability with a 1 thread Raked forward 1.5 Over 3 degrees of camber adjustment in each direction Heavy duty ball joint brackets to eliminate deformation issues, Keller ball joint compatible Ladder bar compatible with the 1.5 ID clamps Extreme duty 1.5 x .120 DOM steel construction Up to 2 of added ground clearance compared to OEM lower arm Mounting accommodations for OEM brake lines using OEM tabs instead of P-clamps Optimized sway bar linkage angles Powder Coated
