Menu servicing has also been introduced to ensure that costs of ownership remain competitive.
The move comes as part of a review by Koelliker UK, SsangYong distributor since January this year.
SsangYong said the review has also improved parts availability with dealers now holding a bigger parts stock.
Doug Lincoln, Koelliker UK aftersales managing director, said: "This is about customer satisfaction and reducing the costs of ownership at a time when fuel prices are going the other way."
He added: "For example, the cost of servicing a Rexton over 30,000 miles is now over £100 cheaper, making it less expensive than a Kia Sorento."
A Kyron oil filter has dropped in price from over £30 to £12.68, while Rodius front brake pads are now £39.89 – down from £68.40.
