Made from durable 9310 steel, it replaces stock gears to deliver reliable 100% lockup traction while maintaining smooth turning and easy installation with its innovative spring and pin design. ## Description The Spartan Locker, by USA Standard Gear, provides reliable traction at a low cost. The Spartan locker's design does not use the thrust washers and has a revolutionary spring and pin design that makes installation a snap!This automatic locker replaces the stock side and pinion gears while utilizing the factory open differential case. A new and stronger center pin fits in oval slots between two inner drivers. Under load the center pin forces the inner drivers outward to engage the outer axle couplers on each side of the case. This provides locked power to both drive wheels, providing greater traction. When turning, one driver is unloaded and the teeth can ratchet across each other creating differential action to reduce tire wear and make turning the vehicle easier. This is one of the most economical lockers on the market today. ## Features - Fits Dana Spicer 30 with 27 spline axles.Material:steel - Made from 9310 steel for added strength - Replaces the spiders in a standard carrier case - Mechanical locker delivers reliable 100% lockup ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007N3P9DA | | Best Sellers Rank | #80,800 in Automotive ( See Top 100 in Automotive ) #10 in Automotive Replacement Differential Assembly Kits | | Date First Available | February 13, 2012 | | Item Weight | 4.64 pounds | | Item model number | SL D30-27 | | Manufacturer | USA Standard Gear | ## Product Details - **Brand:** USA Standard Gear - **Color:** Black - **Material:** steel - **Recommended Uses For Product:** Automotive - **Special Feature:** Lockable ## Images ![USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Image 1](https://m.media-amazon.com/images/I/412V2lWfsWL.jpg) ![USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Image 2](https://m.media-amazon.com/images/I/51kcKbeJDOL.jpg) ![USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Image 3](https://m.media-amazon.com/images/I/51yk+MSPWSL.jpg) ![USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Image 4](https://m.media-amazon.com/images/I/519v9zDNG2L.jpg) ![USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Image 5](https://m.media-amazon.com/images/I/51BPyyfu05L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will these fit my 1995 jeep wrangler yj? should i put them on the front, back, or both?** A: Yes this will work very well in your front High pinion Dana 30. You would need a different locker for the rear Dana 35 in your YJ but i would personally not put an auto locker in it. You will break the dana35 easily. if you really want a locker for the rear - consider swapping the axle for a ford 8.8 or even a dana 44 out of a waggoneer **Q: will this work on my 87 xj?** A: Yes, this locker will work GREAT as long as you have the Dana 44 Rearend.Let me know if you have any other questions.Thanks,BRYDON641-751-8060staticz2229@gmail.com **Q: Will this fit my 2007 Jeep Unlimited with Dana 44 rear axle with no additional shims or parts?** A: Yes this should fit in your 44 using the same shims you already have in there. This will pop considerably on pavement in your rear diff. I have it in my front and it behaves like an open diff when in 2wd. It locks up in 4wd and becomes stiffer to steer but climbs rocks much better. I have the D-30 front. **Q: Does this locker make noise on tight turns?** A: Yes, all lunch box type lockers make a clicking noise on turns. On slow tight turns you may occasionally hear and feel a loud banging. I have this locker in my front D30 and while turning into a parking space I turn slowly and don't accelerate while doing this type of turning. As others have said, it's normal. ## Frequently Bought Together - USA Standard Gear Spartan Locker for Dana 30 Differential 27 Spline (SL D30-27) - Dana 30 Differential Cover Gasket D030 - MG21103 Dana 30/44 Front Axle Tube Seal Pair For Jeep Wrangler JK JKU 2007-2018, YJ 1987-1995, TJ 1997-2006, LJ 2004-2006, Cherokee (XJ) 1984-2001, Grand Cherokee (ZJ) 1993-2001 (2PCS Red) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/16347465-usa-standard-gear-spartan-locker-for-dana-30-differential-27](https://www.desertcart.tn/products/16347465-usa-standard-gear-spartan-locker-for-dana-30-differential-27) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-27*
