It's time. Since 2006, Rugged Rocks Off Road has been dedicated to providing top-quality Nissan 4x4 parts and accessories, supporting the nissan off-road community with passion and commitment. Your support has been instrumental in my journey, and I have been honored to be a part of your adventures. ​After much consideration, I have decided to close the sale of Nissan parts at Rugged Rocks Off Road to focus on developing advanced mapping products through Rugged Routes at ruggedroutes.com. This direction aims to enhance your off-road experiences with innovative off-road mapping solutions for wide varietey of motorsport vehicles. A few products on the Rugged Rocks homepage will remain temporarily available during this transition and exisiting orders will be filled.

It has truely been a great journey as an integral part of my adult life for nearly 20 years, has shaped me as an individual, and introduced me many new friends. Moving on has been a heavy and emotional decision that should have probably been made years ago to support a healthier lifestyle. Thanks again for all the suport over the years, it's been a ride.
See you on the trail,

  • Air Locker Differential Spreader by ARB

ARB’s Air Locker Differential Spreader is a professional automotive tool that no differential installer should be without. Most common Salisbury style axle assemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve the required carrier bearing pre-load during set-up. Stretching the housing casting (or ‘pumpkin’) open by sufficient enough force as to allow extra shim to be added to create the pre-load is the method that the OEM manufacture’s endorse, and most manufacture’s have included special ‘spreader sockets’ in the housing for exactly this purpose.

Insufficient pre-load can result in bearing failure, or ring and pinion failure on any differential, and possible oil/air leakage issues in an Air Locker Differential. As a part of ARB’s Air Locker Tools range of differential service/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.

Features:

- Designed by ARB to quickly and easily install onto most shim adjusted automotive differentials

- Allows the housing to be stretched in a safe and controllable way which reduces the risk of causing permanent damage to the housing (i.e., from overspreading the housing)

- Pre-drilled with a hole pattern that suits most of the commonly available axle types.

- Also suited to pre-loading shim adjusted Banjo style axle assemblies (e.g., Isuzu 26 spline).

- Comes in a durable carry case with a dedicated powder coated parts tray for easy storage and transport

- Economically priced at roughly the labor & materials cost of having to re-preload one axle (i.e., a differential that was set-up without a spreader that is now showing symptoms of under pre-loading)
