SVS ATB Helical Front Limited Slip Differential Fits Nissan R32/R33/R34 Skyline GTR & C34 Stagea 260RSGTR32340

Made in England

Announcing the 'SVS' (Special Vehicle Services Limited) Nissan GTR Front Differential range now available for the Nissan Skyline GTR BNR32/BCNR33/BNR34, Nissan C34 Stagea 260RS, and the Nissan R35 GTR platforms!

We here at Special Vehicle Services Limited were the pioneers in the torque biasing differential to suit the Nissan Skyline GTR R32, R33, and R34 GT-R chassis.
We started sales of these back in 2003, having discovered that a clutch plate or ratchet style differential mounted in the front axle produced a very adverse street driving experience (slow speed manouvres and parking became a literal nightmare). The torque biasing design, when installed, still feels like the stock 'open' unit. Improvements are quite noticeable when comparing track times and especially in wet conditions.

Our first GTR front torque biasing diff customer was an Australian endurance racing team competing in long, gruelling events in Tasmania, along with other circuit use. With our differential, not only did they fail to break them, but they completed the series as overall class winners and continue to use them to this day. This is what initially launched us into GTR torque biasing differential supply for the Nissan R32/R33/R34 GTR & as of recently, the Nissan R35 GTR models. 

At the time, we had also been helping the well-known Japanese tuning giant Trust Co. Ltd (GReddy) with the development of 6-speed gear kits for the GTR since 1992, and later developed a full sequential replacement unit, using our own car as a template for testing. Our supplier regrettably changed the design of that transmission, and the replacement no longer would fit the car without cutting the floorpan, not something we support in the business of supplying direct-fit products. This event signified the beginning of the end of our relationship with them.

From 2020 onwards, we have been seeking a viable alternative. The 3J driveline was the source for our SVS differentials, which had previously been delivered as 'LM' units for the R35 GTR via Litchfield Motors and 'JHH Racing' units for the R32, R33 & R34 GTR differentials. With our 3J driveline supply, we finally decided to brand them as our own. Something we clearly should have done back in 2003.

Our differential is a British-made torque biasing design, manufactured by 3J Driveline and marketed under their 'UL-Trac' branding in their merger with the Longford Gear Co.
3J had previously created this differential for one of our competitors, who then switched brands. We saw this opportunity to continue our 33-year history in torque biasing differential sales and development. 
Together with our founder and 3J Driveline, we bring over 60 years of combined differential manufacture and supply experience to the market.

We are hoping to announce a rear torque biasing unit for the R32/R33/R34 models in the forthcoming months. Currently, there are no plans for the rear of the Nissan R35 GTR, as we found the overall improvements were minimal when previously made and tested against the R35 GTR OE unit.
