Bolt right up, looks great, functional, helps COG, and a great price! There’s heavier ones from other places, but ultimately the cost of these were better IMO. I’ll buy these every time from now on!Do it! ### ⭐⭐⭐⭐⭐ Good value for TRX4 *by on Reviewed in the United States 2 May 2024* Bolted right on my 79 bronco. Adds good weight, and it looks great! The steering arm linkage hits the diff at full lock, I don’t think it’s a problem but I will probably replace the linkage with a bent one to give more room around the diff. ### ⭐⭐⭐⭐ Tight fit but great otherwise *by on Reviewed in the United States 3 July 2024* These work as they should and look great but one of them was a super snug fit. It took a lot of wriggling and jiggling to get it on the axel, the second went on like butter. I'm only running it on the front so the second is just spare/backup.All in all I'd say these are a good value, not great but good. ## Frequently Bought Together - AMK TRX4 Brass Diff Cover 2PCS Front and Rear Axle Diff Cover TRX4 Portal Axle Housing for 1/10 RC Crawler TRX6 TRX4 Upgrade Parts - HobbyPark 4pcs Heavy Duty Brass Steering Knuckle Weight Outer Portal Drive Housing Cover Counterweight Block for Traxxas TRX-4 1/10 RC Crawler Car - 1/10 RC Chassis Armor Set for TRX-4 Car, Stainless Steel Skid Plate for TRAXXAS TRX4 Sport Body (Podwer Spray), Link Shock Axle Protector for Bronco K5 Blazer Defender 92076-4 82046-4 --- ## 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.pe/products/514024714-trx4-brass-diff-cover-2pcs-front-and-rear-axle-diff](https://www.desertcart.pe/products/514024714-trx4-brass-diff-cover-2pcs-front-and-rear-axle-diff) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-10-12*
