Since BC grinds the world's fastest X3 solid lifter camshafts, makes sense that we deliver the world's lightest solid bucket conversion kit. Features stock O.D. cam buckets that have been DLC coated from Arrow Precision, the best, most reliable bucket available on the market...not some repurposed OEM stock part. Also includes a beehive spring wound by PAC Racing exclusively for BC. This is the same spring that we use in our proven hydraulic kits that has seen in excess of 10,000 rpm. The lightweight titanium retainer features a large shim capture design to keep those 7.48mm lash adjusters from getting loose and ruining your engine. Also includes BC spring seat and valve seal combo as well as stock replacement keepers. Use in conjunction with BC custom ground solid lifter camshafts and you'll be setting records and lowering ET's in no time!
