Warranty & Returns
SPOOL Crankshafts and Connecting Rods come with a full workmanship & quality warranty.
Due to the nature of high performance engines & Motorsports applications we have no control with any of the variables involved in the assembly, tuning or operation of the engine. Variables that we cannot control include but not limited to: the tolerances used on assembly, qualifications of the assembler, tuning parameters used, boost levels, application of the part being suitable and RPM levels reached. In summary we have no control over the assembly or customer modification of our parts in your engine therefore we cannot give a warranty once installed.
All manufacturers of our aftermarket parts offer limited warranties and we will not be responsible for the on goings from there warranties.
"Motorsports" for the purposes of warranty is classified as any automobile activity that takes place off of a public highway, or on a public highway in a competitive environment. ALL Motorsports parts & services sold through Spool Imports are sold "AS IS" without any warranty whatsoever once installed. No claim is made as to merchantability or fitness for particular purpose. The entire risk as to the quality and performance of such parts is with the buyer. Once parts are installed following their purchase, the buyer and not the manufacturer, distributor or retailer assumes the entire cost of all necessary servicing or repair.
MOTORSPORTS PARTS ARE DESIGNED FOR OFF-HIGHWAY OR RACING USE ONLY.
SPOOL Short Motors come with a full workmanship, quality, start-up and run-in warranty. Warranty applies to any workmanship related issues concerning the short motor during the run in procedure as long as the run in procedure is adhered to. Workmanship warranty only applies if bolt on accessories i.e. cylinder head, manifolds, plenums, oil pump, balancer, timing components, sumps etc are installed by a qualified mechanic and installed correctly. The warranty does not apply once the engine is run in.
Oil control is imperative in any competition engine. Oil starvation will cause severe damage to this engine. Make sure oil control systems are installed on this engine that will sustain oil pressure and supply for the intended use such as an aftermarket high volume/pressure oil pump, large capacity sump with internal baffles / trap doors, cylinder head oil drain kit. The correct volume of oil for intended use is also crucial. Incorrect or inadequate oil control systems will cancel any applicable warranty issue.
Due to varying volumes between engine combustion chambers, head gasket volumes, cylinder block heights, compression heights, etc. All piston manufacturers listed / advertised compression ratios should be used as a guide only.
Actual calculated compression ratios may differ from listed / advertised compression ratios for the above reasons and variations.
To obtain an exact compression ratio, all specific measured specifications and volumes for the particular engine are required and custom pistons manufactured to suit.
All Spool products have been specifically designed for off road ie; race track, drag strip and non-highway/street application only. As the installation of this part may affect or impair your OEM (Original Engine Manufacturer) vehicle’s emission control performance and may not meet the emissions standards of the local Government regulations.

STD Bore Pistons
Spool Imports does not generally keep any STD bore pistons in stock, we can order shelf stock and custom pistons in std bore if requested.
Std bore size pistons are not recommended in a used bore for any performance engine unless re-sleeving the block back to std bore size or using a new block.
All piston manufacturers have a specific piston to bore clearance that they recommend. When using a used std bore there is already wear in the bore, hence the manufacturers piston to bore clearance cannot generally be met due to the existing wear in the used bore, especially after honing the used bore. Excessive piston to bore clearance tends to cause early and excessive blow by issues.
Most piston manufactures recommend going to the first oversize and having the cylinder block bored to suit the new pistons with the recommended piston to bore clearance.
If STD bore pistons are requested and there is a piston to bore clearance issue we will not exchange or refund, due to the reasons given above.
