07-13 GM 1500 Mid Travel Arm Kit 2wd/4wd Kit
This is a "true" Mid Travel kit and it is designed to give you the most the most bang for your buck and ease of installation on your two and four wheel drive GM truck. The 2wd version can be used with or without Mazzulla's fabricated spindle, but for maximum ground clearance, strength and the ability to run a 37" tire the spindles are a must. In addition this kit can use the factory Coilover shocks or Mazzulla's custom 2wd - MZ/King 2.5" Coilover shocks for 14" of real suspension travel. The 4wd version uses the factory spindles and it comes with a pair of 300m heat treated axles. This kit must use Mazzulla's custom 4wd - MZ/King 2.5" Coilover shocks for a total of 11" of real suspension travel and maximum of 35" tires. Wheels must be 17” x 8” with no more than a 4.625” backspacing.
The inner pivot cups are made of thick 1/4" tubing and fit precisely over machined Delrin bushings along with a grease Zerk for added lubrication to eliminate wear and noise. They use 3/16" formed sheet metal plate and MIG weld the entire part in two different fixtures to ensure perfect fitment on your GM chassis. The outer pivot is a machined 4130 Chromoly Uniball cup that houses an Aurora 1" Uniball bearing for ultimate strength. Lastly they have included a 17-4 heat treated stainless tapered adapter pin that connects the upper control arm to the spindle using a 1/2" 12 point aircraft bolt.
