LSK is proud to introduce the GM 2500HD/1500HD 2wd/4wd Race Kit. This race kit uses a set of custom upper & lower control arms, fully fabricated spindle, extended heim tie rod w/ weld on centerlink clevis adapter plates and plate shock towers to vastly improve the on & off road ride quality. This kit is best suited for those who use their vehicle as a dedicated off road rig or one that sees occasional street use.

Important Notes:

  • Welding is required - this is not a bolt on system and will require proficient knowledge in fabrication to perform the installation

  • This particular kit uses a 8" 2.5" coilover and an 8" 3.0" or 2.5" 3-Tube bypass, a larger bypass can be run but would require a custom tube layout

  • Coilovers require a specific fitting layout - if using your own coilovers please contact our sales team to make sure the configuration you have will work with this kit

  • Shock hoop is  listed as an option because most installers wish to add an engine cage but may want to run their own layout - choose this option if you would like to use our supplied shock hoop by itself or as a base for your installer to build an engine cage off of. Optional Shock Hoops are constructed out of 1 1/2" .120 wall DOM tubing

  • Kits are normally in stock, however, a lead time of 3-4 weeks for a finished batch is typical on this kit when sold out. Please contact our sales team to verify if product is in stock (While it displays "In Stock" on the website, inventory levels are constantly changing and is not updated in real time)

  • Extended axle shafts are configured to use OEM inner and outer CV joints - RCV HD joints can be added for an additional cost, please contact our sales team to have this option added to your order

  • Coilover/Bypass lead time depends solely on King Shock Technologies. Typical lead time can be anywhere from 8-10 weeks on standard King blue finishes.
