All of our championship-winning X-Line and R-Line race calipers are machined from high-grade aerospace aluminum billets, and we’ve chosen to manufacture the X-Line 4x4 range from the same material. Machining from billet is admittedly an expensive way to manufacture calipers but it results in a finished product that exhibits exceptional levels of strength and rigidity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Surface Finish:\u003c\/strong\u003e Either a Red anodize (type-2) or a Dark Grey hard anodize (type-3). The anodize dyes used for our Red finish have been carefully selected to offer the maximum UV and temperature resistance to ensure long-term color retention. The Dark Grey hard anodize is our most durable finish and is the finish that we use on all of our R-Line off-road race calipers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Logos:\u003c\/strong\u003e Advanced laser etching technology\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Cross-Bolts:\u003c\/strong\u003e Silver zinc flake coating through bolts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Pistons:\u003c\/strong\u003e 6-pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Fluid Crossovers:\u003c\/strong\u003e Hidden bleed screws for protection against damage from stone impacts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Maximum Temperature Recording (MTR) System:\u003c\/strong\u003e All Powerbrake X-Line 4x4 calipers feature our MTR system.
