We understand that professional engine buyers require clear product identification, accurate fitment information, transparent component configuration and reliable export coordination.
Our B2B cooperation process can be arranged around your purchasing requirements:
Application matching: Provide the VIN, original engine code and OE reference for fitment review.
Product specification: Confirm the engine condition, included accessories and inspection scope before order confirmation.
Wholesale quotation: Pricing can be evaluated according to order quantity, engine configuration, product condition and destination.
Export coordination: Packaging, shipping method, delivery schedule and export documents can be agreed upon before dispatch.
After-sales communication: Technical questions and agreed warranty terms can be documented in the order confirmation.
Stock availability, minimum order quantity, warranty coverage, lead time and production capacity must be confirmed for the actual order rather than assumed from a general product listing.
Engine assemblies require suitable packaging to protect machined surfaces and sensitive components during international transportation.
Before shipment, the buyer and supplier should confirm:
Packaging method and crate dimensions
Gross weight and net weight
Protection against moisture and corrosion
Loading and unloading requirements
Shipping method and destination
Commercial invoice and packing list
Applicable export documentation
Incoterms, insurance and delivery responsibilities
Freight charges and delivery times depend on the shipment dimensions, destination, shipping method and agreed trade terms.
Q1: Is the Land Rover 508PS a supercharged engine?
Yes. The 508PS is associated with the AJ133 5.0L V8 supercharged petrol engine. The naturally aspirated 508PN is a different version and should not be assumed to be interchangeable.
Q2: Will this engine fit every Range Rover 5.0L V8?
No. Compatibility depends on the original engine code, production year, vehicle specification and applicable OE number. VIN verification is recommended.
Q3: Does the engine assembly include the supercharger and all accessories?
Not necessarily. The supplied configuration depends on the actual product. Please request a written list of included components and current product photographs.
Q4: Can you provide wholesale pricing for distributors?
A B2B quotation can be prepared based on quantity, engine condition, component configuration, destination and shipping terms. Please provide your purchasing requirements for evaluation.
Q5: Can you supply technical or inspection documents?
Available documentation depends on the specific engine. Please specify the required technical data, inspection records and export documents when requesting a quotation.
Q6: What information is required for fitment confirmation?
Please provide the VIN, vehicle model, production year, original engine code and original OE number. Engine label photographs are helpful when available.
