Let Iron Pig install your ARB locker right - buy any ARB Air Locker at regular price, and get the installation into your diff for FREE! (All applications apply, call for those not listed). Special applies to loose differentials at the IPOR shop - not local? Send us your diff, we will professionally install the locker and return it to you ready to bolt in to your housing (plus shipping). If you have a Dana style axle the vehicle will need to be here at the shop to qualify, if that isnt possible we will be happy to provide a discount on the part itself. We also have ARB compressors in stock along with the tire inflation kits. We guarantee the lowest prices - shop around and call us last with your best price - we will beat any competitor that is an authorized dealer!
