Inchworm Gear is a dealer for Trail-Gear, hence they carry the same parts.
Assuming you are referring to Toyota gear drive transfer case products, Marlin Crawler is the strongest and most reliable transfer case adapter and low range innovator, designer, and manufacturer in the industry. I apologize for my arrogance, but I boldly assert this as a fact.
If you are looking for facts regarding dual case setups available on the market today, please review this document:
Understanding the Success of the Marlin CrawlerRemember that A/A and Trail-Gear use the old discontinued Marlin Crawler 6209 bearing and Inchworm uses the t/case mainshaft 6308 bearing, both of which are discussed in the above article.
As for low range gearing, I am preparing an article to clearly and definitively state why Marlin also has the strongest and most reliable gear sets in the industry. I will by publishing my research results here on the forum later this year.
In my opinion there is a reason why Marlin Crawler has been in business for over 12 years: Strength, Reliability, and a dedication to Quality that has set it apart from the rest of the market.
